Re: [Elecraft] Noise from KAT500?

[Dave B via Elecraft]

To me, it sounds like that when the ATU is inline (& I presume you let 
it tune to that antenna at some point.  Yes/No?)
The antenna is better matched to the transmission line, so more of the 
on-air "ambient" noise is delivered to the RX.


I get the same here, where 60m is quite noisy anyway.  At times over 
some 10dB difference!  Even more noticeable on 80m and 160m.  Where the 
"bare" antenna (random wire sloper) is naturally even more inefficient.


Do you have a passive/manual ATU you could compare with, using the same 
RX and Antenna?


If it was SMPS noise, I'd expect (in your case) a 60 or 120Hz based buzz 
to be part of that "noise".  But I don't hear that.

Re: [Elecraft] - K3 INTERFACE WITH LDG Z100A

[Dave B via Elecraft]

Hi Dan.

As I suspected, been done already!   Using a PIC microcontroller in this 
case.


I have one of the early LDG / Icom specific tuners (well, matching 
units) in my 4x4 that works well with the IC-706Mk2G, well, that's what 
it was designed for of course.


I have played with an Arduino between my shack radio (TS-870s) and a 
Yaesu FC1000, it sort of works, but I still need to "finesse" the timing 
between radio and tuner controller.   (Someone one time suggested 
talking direct to the outside tuner itself, but hey ho.)


I could not see anything in the AH-4 "Manual" where it can be configured 
for Yaesu/Icom or Kenwood, so I presume different firmware is needed for 
the PIC for each radio.   Elecraft rigs of course largely emulate the 
generic Kenwood remote control protocol, so it should be possible with 
that interface to do what's needed. (There is no such thing as a 
"Standard" universal rig control protocol, sadly...)


However, I think (from a quick skim through the document) that it can 
key a radio, and produce an audio tone that would in turn generate a 
"carrier" (dial +- tone frequency) from a SSB radio to do the job.  
Neat!  Just a bit more wiring to mix in an audio tone into the mic 
input, or in the case of some Kenwoods, just plumb the thing into the 
AUX/Accessory port, where as well as PTT you can feed TX Audio in too.


If the "Tuner" used can provide an ALC voltage back into the rig, to 
control/limit the TX power to what it needs, even better.


The firmware is quite well documented PIC source code, so could be 
adapted/altered as needed by anyone.


An interesting kit.

Its been a bit since I’ve owned an LDG tuner, but, to my recollection, 
the interface was similar to what Icom uses on their AH-4. The LDG

simple cable. And, there were, at one point, a couple sites online for 
“universal” interfaces to use with an AH-4 - here’s one:


https://www.hamoperator.com/Hamoperator/AH-4_Universal_Interface.html

http://www.hamoperator.com/Hamoperator/AH-4_Universal_Interface_files/ah4-manual-5.pdf

Near the end of that PDF is a description of how the interface works, 
including what signals are needed to do the tuning.


Again, to my recollection, the LDG tuner’s I’ve owned also have an 
auto-tune mode, where, if they see a mis-match while you’re 
transmitting, will automatically go through their cycle to find a 
better match.


The LDG group previously mentioned has Manuals available online as zip 
files.


Apologies if this is a bit vague, I sold my LDG, and just use the 
built in tuner on my K3 these days. I will say I think it would be 
nice if there was an easy drop in product or method for using a non 
Elecraft external or an at-the-antenna tuner with the Elecraft, such 
as the LDG or Icom’s, but I’ll leave that to the savvy entrepreneurs 
to bring to market.

Great info, Dave.

    Thanks...


Might be a little technical for some users.
    Well, this is a "technical" hobby, and such technicalities are not 
going to go away anytime soon I suspect.  Especially in regards to the 
use of computers in the shack.


The #1 problem most hams have is they plug their USB-To-Serial 
adapters into different USB ports, and the COM port number changes.
    That is well known, and can be managed, especially with devices 
that have a unique "identifying feature" in their USB descriptor that 
the OS sees.   (FTDI rule the roost in that matter!)
Not only that, Windows leaves the old port number reserved much of the 
time.

    Yep, but again, that can be managed, using USBDview if nothing else.


I have an in-depth blog post which talks about this in layman's terms 
on my blog.  See 
https://blog.remote.radio/2020/11/automation-in-amateur-radio-rs-232-for.html
    Good info, but many of the hardware solutions (that do work well) 
edgeport etc are beyond the purchasing ability of many Hams. Plus, they 
rarely show up surplus or at ham-flea markets (here in the UK at least...)


    Lantronix are more well known for their LANPort devices.  Very 
good, but needs a certain level of knowledge to use, plus application 
software needs to be able to use TCP/IP connections to other devices.   
(Or tunnel a VCP over a network link.)


As explained in that blog article, there is a way to solve this 
problem.   Digi, a company who has been in the business for many 
decades, has a series of USB-to-Serial adapters
called Edgeport, from 1 to 16 ports.   The great thing about Edgeport 
devices is they have a driver and utility.  If you use that, the COM 
port number is associated with

the BOX, not where it is plugged in.

Edgeport devices are quite expensive when new, but can often be found 
on the surplus market (ebay, etc).  They have been used to do baudot 
by hams for decades.  I use them all over the place.
I have 4,8, and 16-port USB-to-serials that are surplus to my needs if 
anyone is interested.


They solve the RS-232 port issue every time!


    The simplest solution, is to (sorry) learn and understand the 
issue, then use stable and easy to uniquely enumerate devices, (FTDI is 
the only vendor that shows unique serial numbers AFIK.)


    As before, Ham Radio is a Technical Hobby by it's nature, it 
worries me sometimes when even highly respected Hams who can and have 
worked the world (i.e. are Superb operators with worked all continents 
on many bands and modes etc) seem to know very little about the 
technical aspects of the kit they own and use.

Windows has the means to "Fix" that.  (Known to work up to Win10, that I 
have personally tested it on.)
Find those details here:- 
https://sourceforge.net/p/fldigi/wiki/windows_com_howto/
I wrote much of that after hours of "fun" some years ago...   As above, 
it works well with Win-10.



For Linux users, look up and explore the world of "udev rules". But...
They are only really easy to setup, if a USB device has a unique 
"something" in it's USB descriptor, that the OS uses to identify it.  
Such as a Serial Number.   FTDI devices have unique sn's, but Prolific, 
SiLabs and others sadly do not.  So, it gets funky if you have several 
of the same type of device that all "look the same" to the OS.


(Newer genuine FTDI devices also have the ability to have that serial 
number (and some other settings) re-programmed!   Fakes seem to take the 
reprogramming, but the new data does not "stick".  Don't ask how I found 
that out!)


However, you can use the "connection path" between the OS and the 
Device, as a deciding factor, but then you are forced into hooking 
everything up "EXACTLY" the same each time.  (Hub's and all...) But it 
does work.


Using them, you create "symbolic links" to the actual port used, so for 
example my VHF radio appears as /dev/ttyFT736  Regardless of which hole 
I connect it's associated FTDI serial adapter to on the PC (or via any 
hubs!)  Or what /dev/ttyUSB* the OS re-assigns it to if things are 
re-enumerated for whatever reason.)


For example, this is the rule for my ancient FT-736

#FT-736r
SUBSYSTEM=="tty", ATTRS{serial}=="A50285BI", SYMLINK+="ttyFT736"

Flrig and most other software both accept symlinks and work well.

(For the odd software title that insists on using the full /dev/ttyUSBx 
for example, they often store their settings in a file that can often be 
edited with a text editor, where you can in effect force-feed it the 
symlink.   The fun part is finding where that is stored!)


The exact details of how to use udev rules are way to much for this 
list, but as usual, there are many websites that can furnish such info, 
plus some examples.   Has to be said though, different "flavors" of 
Linux, often store such rules in subtly different places to others.



I have zero experience of Apple Mac's.  But they use a custom version of 
BSD as their OS, that is more like Unix than Linux.  So it is likely 
some if not all of the above could work on them too. If Apple let you 
dig that deep and meddle...



Hope some of the above helps, and or gives people some ideas how to tame 
things.

[Elecraft] PS: Elecraft Digest, Vol 219, Issue 2

[Dave B via Elecraft]

PS:

As another respondent said.  The "Best" way to get remote access to 
anything (regardless of OS) is a proper VPN.   But, do not underestimate 
the learning needed to "do it right" especially for systems that have an 
embedded OS.


(We are not talking about the "consumer" VN's that hide your internet 
traffic from your ISP, or other websites.  In this case were talking 
about a dedicated point to point VPN.  A totally different beast, though 
behind the facade, the background processes are similar.)


If you use an intermediate Router, between your K4 (and other shack 
stuff) and your home router, then it is the intermediate router that 
needs to have a VPN endpoint running.   Or, have a PC with multiple LAN 
cards, that itself can work as a router/VPN end point.


But, then you also need a VPN on your remote client PC/device to work 
with it, and you need to religiously keep that PC up to date. A 
Raspberry Pi could do the task for example, at both ends.


Yes, it is the "way to go", but as above, do not underestimate what you 
need to learn, so as to do it correctly, else it could be as bad as a 
wide open system.


Look up Wireguard for example (the new shiny easy to deploy custom 
(free*) VPN.   Or, OpenVPN (also free*) but though that is time-served 
and proven, but it is not trivial to configure correctly.


(* Free, as in no $ cost, just time to learn and configure.   There are 
some scripts that can do most of the work for you, but again, you need 
to trust the author of such scripts to have done things correctly, 
including not including any cracks or back-doors!)


Firstly, decide what you want to do now, and perhaps in the future, and 
plan things.

Hi.

At the very least, see if the embedded Linux it uses (what version of 
what distro, anyone know?  I've not seen anything re that mentioned...) 
has a firewall facility you can invoke and setup. Even if it is only 
possible from the command line.   They can have full network

can be setup for what you "Want" to do, and still protect against what 
you don't want to happen.  (Remote file access etc.)


If you setup for remote access via SSH, then read up how to use 
Certificates for authentication, and not rely on passphrases.



A semi instant solution, would be to "hide" the K4 behind a reconfigured 
wired router.  That way, it can reach out for any authorised updates, 
but nothing can "see" it from the rest of your LAN.  (Unless you "need" 
it, in which case, that extra router can be configured to do so.  
Effectively much like a hardware firewall. But make sure that routers 
own OS is all up to date too!)


You could put other Shack connected stuff on the same protected LAN as 
well, if needed.   Else, see if your existing router can create and 
manage an isolated VLAN for the K4.  Preferably on a separate physical 
cable run.


Linux as a whole is less troublesome than "some other" OS re malware, 
but it does exist, also so do vulnerabilities.  It is just that most 
Linux users would spot a behavioural change and go searching for stuff 
to kill off.
(If you think Windows updates too often, you aint' seen nothing yet, 
security updates are issued as needed, not waiting for one batch a 
month!  But with most Linux's, updating, even a kernel update is only a 
few minutes of your time, not hours like that "other" OS)


Because of that, it is less targeted by the usual bad guys, but sadly 
that is beginning to change. :-(  Thankfully though, Linux generally has 
the tools to do manage that and protect itself without needing to 
download other stuff.  But it does need time and learning how to do so.


If you are really concerned, do not connect your K4 to your LAN, except 
when needed (official updates etc.)   Or if you "Need to" (Remote Shack 
working etc) then plan it, and install the needed protective devices 
(dedicated firewall router for example) to hide it behind.


The first thing to find out, is just which embedded Linux is used in the 
K4, and what protective tools are provided as standard.  If there is not

to why such was left out.

Ladies and gentlemen,

Perhaps this is old news to some however I thought it worth asking before my 
radio arrives.  Given the K4 now has direct Ethernet connectivity, how 
vulnerable is it to malware, bugs, worms and bad internet stuff in general?

What is recommended for the radio itself besides protecting the associated 
computer?  For example, should a VPN be used or is the risk considered low 
enough to disregard?

Thanks in advance

Re: [Elecraft] K4 Remote Software?

[Dave B via Elecraft]

I heard that one of the major competitors is working on TSFoldDX mode.

They fold space and time so that you can just talk to the DX face to
face and hand the QSL card over in person.  Sadly, that was put on hold
due to Covid concerns.

They had it working briefly about 10 years ago, but the development of
the pocket Nuclear power pack is a bit of an issue since the Fukushima
problem.  Caused incidentally by another unexpected aspect of folding
time and space from a planet based point of view!  (But you didn't hear
that from me!...)

Seasons Greetings, Happy New Year etc, and GD DX to All.  (Though we
might be swiped by another solar event today, wrecking the ionosphere
for some, but causing some nice lights in the sky for others perhaps.)

PS:    As I believe the K4 uses a Linux based embedded computer.  The
options for remote control are many and vast.  Some even will work with
a Windows based client.

I've not even seen a K4 let alone got hands on one, but if not already
present (I could not see reference of such in the preliminary user or
remote software control manuals) it should not be beyond possible to
have a small web server built into it's system with proper security
features (certificate based authentication and encryption) that you
could connect to with any existing web browser to gain a full and secure
virtual front panel remotely.

Or, a "K4Remote" tool, written in Java (or other cross platform
environment) that would run on Windows, Mac or other Linux machines, to
connect to your K4, and provide a full remote front panel and audio etc.

The difficulty with all of them is not the remote control, or front
panel updates, but passing audio and other time critical data (CW key
etc) with minimum latency.

Also, if at all possible, do not connect directly to the Negative side
of the battery without a fuse.

In the event of a (not uncommon) fault with the batteries own ground
strap, your radio etc will try to conduct a large proportion of the
engine cranking current, that doesn't end well.  (I have seen CB sets
explode under such conditions!)

Sketch out the starting circuit, then include your radio's power wiring
and you'll see the problem.  (Include the antenna ground connection!)

With some modern vehicles, such a connection can also affect the battery
charging system behaviour, as a bulk current sensor could be bypassed by
your wiring resulting in overcharging the battery under some conditions.

Some vehicles also use the alternator to provide extra engine breaking,
resulting in large charging currents and voltage changes for short
periods (seconds) while overall the battery is never "fully" charged, to
accommodate such short term usage without damage.

For Safety, it is best to connect the radio -ve direct to the vehicle
chassis ground, not the battery negative.

If you do have to connect directly to the vehicle battery negative (for
a temporary install, during an EMCOM event for example) then check the
condition of the vehicles battery ground strap first, AND use a Fuse in
the radio -ve lead.  (If you ever find that fuse has failed for no
"apparent" reason, you need to check the health of vehicle battery
cabling in detail.)

Always check the vehicle handbook for advice about such things too.

Having suffered a vehicle electrical fire* while driving, I can tell
you, you do not want that experience.

(* Unrelated to any amateur radio matters, it was due to a "money saving
feature" by the vehicle maker, that over time eventually caused a short
to ground of a lighting circuit, that was also not fused!)

Take care.

Re: [Elecraft] Old DOS computers

[Dave B via Elecraft]

If anyone thinks a "New" PC out of the box, is "secure"?

Think again, they are far from secure, unless you spend several hours 
disabling a lot of "phone home" & auto update facilities in all the 
pre-installed (and usually unwanted) crap-ware (sometimes including 
parts of the OS itself) that are often nigh on impossible to un-install.


If you want "security" never connect it to any network, certainly never 
the internet!


If you do use the internet, then at the very least disable UPnP in your 
gateway/router device.   And keep said gateway/router device firmware 
up-to-date (and ensure that UPnP is OFF after such updates!)


And as for efficency...   Have you measured the power consumed by a 
modern PC when watching streamed video for example?


Much of the older technology was built for reliability too, not the 
cheap mass produced lead free tin whisker prone stuff of modern times.   
Dont either fall into the trap that SSD's last forever.  They wear out 
too, but in different ways.


Best to use a SSD to boot from (largely read only) but keep the swap 
file and user working data on a rotating-rust drive. Archives can go on 
the SSD (as well as an off site store...)


I wonder if the Linux based OS in the K4 is locked down, firewall on and 
configured to drop incoming requests by default, with certificate only 
based remote access for example where needed, and full (different 
certificate) authentication when/if it phones home to Elecraft, to help 
mitigate MITM spoofing issues.   (Man In The Middle.)


If you can "see" it (or any other PC/device) on your network, it(they) 
is(are) not secure.


You wouldn't want your shack to be compromised by malware in the radio, 
or lightbulb!  (Yes, there is malware/ransomware for Linux, not common 
yet, but nasty.)

Re: [Elecraft] Gurus

[Dave B via Elecraft]

Should be easy to gauge...

How "clean" (or otherwise) is his signal on your RX, with no antenna 
connected, and all the RX attenuation switched in.


Perhaps also fit a well screened dummy load to the rig's antenna port(s)

Also disconnecting just about everything else except the power (and put 
some ferrite on that!)


All that should greatly reduce the level of his signal that your radio 
"see's" to manageable proportions.


Even turn the RF gain down too if needed.

If he's not splattering as much or at all, then it is likley your RX is 
being overloaded.


If it sounds just as bad, and splattering just as wide, then likely it's 
his end.


Regards to All.

90'C is too hot for the heatsink.

One wonders what the actual device junction temperatures (the critical
value) might be for that, but that can't be measured directly.  You need
knowledge of the actual power being dissipated, and the various thermal
resistances between junction and heat sink, where you can measure
temperature.

Plus the difference between what the heatsink sensor records, vs the
temperature at the device, varies as well.

Solid-state power devices (DC and RF) do not like heat, the hotter they
are, the less likely they are to last a long and trouble free life.  
Plus, all the thermal cycling (heat/cool) can stress soldered joints to
them that will eventually fracture and cause a fault.

Yes, keeping a stable (even hot) temperature will reduce thermal cycling
stress, but the overall MTBF of the devices will still be very much
shorter at elevated temperatures than if they were kept cooler.

Plus, RF device production life-cycles are notoriously short as the
development pace is fast, especially with LDMOS devices.  Also, often
the new "better" devices, are different enough to /not/ be drop in
replacements.  Electrically or physically.

As for cleaning.  As often as needed, every site/shack is different.  If
you see dust accumulating on the outside, it's inside too!

Many commercial amps have air inlet filters.  But they need to be kept
clean, as a clogged filter is just as bad for cooling, as an inadequate
heatsink/fan combination and no filters.

Regards.

Re: [Elecraft] How to download firmware into K4

[Dave B via Elecraft]

For a fraction of the price of one of those Amazon things ($60 US, of
unknown repute and support.)

You could buy one of the old Lynksys Blue/Grey WRT54G routers (Well
known with lots of free expertise "out there") and re-configure it to
work as a WiFi/Wired LAN Bridge.

Generally rock solid hardware, and as a bonus, they work well from a 12V
DC supply.  Plus with far better antennas than that Amazon thing, and
more wired ports too (5 usually in total, all usable for other purposes
as needed.)

Reuse, Repurpose (& last resort) Recycle.

[Elecraft] KX3 firmware issue?

[Dave B via Elecraft]

Hi.

I'm seeing strangeness between the command values used to set the AF
Gain, and what is returned when you query it, even using the KX3 utility
software (v1.2.12.21)

The front panel control range is 0 to 60.  The values returned when
querying the radio follow that just fine as you query it while twiddling
that knob.

But... Sending the command AG060; does not result in maximum AF Gain. 
For that, it needs AG100; sent to the radio.

If you send AG060; (or AG60;) then the "volume" is about 50% of maximum
(by ear.)  Poll the radio with AG; and it returns AG060;

But, if you gently turn the AF Gain control counter-clockwise, the front
panel volume setting shows AF 59, but the volume (by ear) goes UP. 
Turning the control clockwise, will also bring the volume up, but the
value stays at 60.

If you send AG100; to get maximum volume, and then send (for example)
AG070; to reduce it, it does reduce.  But, if you query the radio with
AG;  It returns AG060;

As before, all of the above is when using the KX3utility, to send and
receive commands and parameters between PC and radio.

PC's OS is LinuxMint 19.3 64 bit all up-to-date.  Also using a genuine
KXUSB cable, FTDI chipset version.

My KX3 MCU firmware is Rev 02.95 and DSP firmware is 01.52

MCU or DSP Firmware issues?

I Initially found this, when investigating to "adjust" Flrig to work
correctly with the KX3, using the radio's native parameter values. 
Currently it seems to use K3 remote command values for most things.

As anyone who has messed with the remote control of these radios will
know, a KX3 is very different in detail, to the K3 in many command
parameters.

Seasons Greetings etc.

[Elecraft] KX3util error on Linux Mint 19.3 64 bit.

[Dave B via Elecraft]

Hi.

Decided to update the KX3.  (Having also just updated the XG3Util
software, and found that device was up-to-date.)

Downloaded the current kx3util software (Linux x86 version) from the
Elecraft site, and got that "installed" such as it is.

Comm's established with the radio via genuine Elecraft lead, firmware
duly identified, new (current) versions of MCU and DSP pulled down from
Elecraft OK, and programmed into the radio, all OK.

As I have had some minor transmit issues in the past, I then backed up
it's existing configuration, and proceeded to the Transmit calibration tab.

Clicking on "next", nothing, nada, zilch.  No error messages in the
underlying terminal screen I launched it from either.

Clicked on "Help" and ...

"The GtkHTML library required by the HTML Help Viewer is not installed."
is shown.

When OK is clicked, back to the calibration dialog display.

Tried the Help button, nothing, except in the underlying Terminal session:-

Could not load libWebKit
Could not load libGtkHTML

is shown.  ( Hmmm... WebKit, isn't that some proprietary Apple thing? )

Anyway, the only button there that does anything is the "Cancel" button.

So, where to next!

I have presently mislaid the user manual by-the-way, and I had odd
errors attempting to pull a version from Elecraft with FireFox.

Any suggestions welcome.  Oh, anyone who tells me to update to Mint 20,
will be shot!  That isn't going to happen yet a while.

73.

Dave G8KBV.

Re: [Elecraft] Smoke detectors

[Dave B via Elecraft]

Well, RF (AKA "Radio Waves") can falsely trigger all sorts of equipment
that was not "designed" to work with, or be influenced by them.

That is the classic EMC Susceptibility or Immunity problem.  Basically,
poor design and/or implementation of the affected (or sometimes bad
installation of an otherwise good) device.

To do it right, costs money, so you can guess the rest.


Not just smoke detectors either.

Re: [Elecraft] Why predistortion ?

[Dave B via Elecraft]

Pre-distortion is often used in modern cellular base-station 
transmiters, and perhaps digital broadcast systems where they have to 
handle multiple carriers simultaneously, "at power".


It dramatically reduces transmitted intermodulation to very low levels, 
allowing such multi carrier systems to co-exist very close to each 
other, improving the reception of the base station by the mobile/handset 
device.  (Lower Bit Error Rate numbers.)  Without spending mega bucks 
for a PA system grossly over rated and inefficient, just to stay in it's 
very linear region, well below the 1dB compression point!  (As was 
common not that long ago.)


As mobile phones these days are also almost all SDR in nature, even they 
may apply pre-distortion to their TX signal, for the same reason.  
Smaller lower cost and lower power consumption PA, but keeping it clean.


"Docherty Amplifier" systems are also often used in other cases, where a 
clean low power class A amp in effect "corrects" the output of a much 
more powerful, more efficient but not as linear (class B) amplifier by 
means of a combiner, dynamically adding or subtracting "signal" as 
needed in analogue real-time.  (Crude over simplification!)


The techniques are as yet not common in Amateur circles, but are 
becoming widely used in several commercial scenarios, so it is only a 
matter of time...  As more and more mainstream radio transceivers adopt 
SDR principles in both RX and TX paths, the cost savings at the high 
power stages become significant, once the software is developed and 
fully engineered.

Re: [Elecraft] KX3 power out

[Dave B via Elecraft]

Hi.

I would not trust a Bird 43 or similar meter for any "Measurements"
whatsoever.

Especially if you cannot prove that the slugs and meter body were
calibrated together.

They are notoriously inaccurate, but are good for quick "power presence"
indications, and "ball bark" VSWR checks.

I honestly do not know why Bird 43's etc, are so coveted by the ham
community, they are awful things for making measurements..

Note that the difference between 8W and 15W, is a bit less than 3dB.
(2.73dB, or less than half an 'S' point!)

And for 3 and 2.5W it's 0.79dB  (Less than 1dB is not bad.)

Also, how good is the MFJ load at VHF, VSWR wise.  The spec says 1.5:1
above 30MHz.  What did the radio say about that?

Re: [Elecraft] Balanced Mic to Unbalanced Connection Follow Up, Question

[Dave B via Elecraft]

Both would work.

Sketch out the equivalent circuit and you'll see why.

As to using a TRS or TS 1/8th (3.5mm) plug, you'll have to consult the
radio's manual to see exactly what's connected to the tip and ring, and
if the sleeve is actually connected directly to the chassis, not via a
convoluted PCB ground trace.

Twisted pair's help cancel out hum and interference pickup, /only/ if
the input to the amp, mixer, or in this case the radio, is itself very
well balanced around "ground/chassis" etc.   As soon as you use it like
an unbalanced system, such advantages are lost.

But yes re the XLR Pin 1, that is a shield that should be connected to
the radio's chassis in either case.  Irrespective of what you do with
pin's 2 and 3...

Re: [Elecraft] Two instances of WSJT on K3s with SubRX?

[Dave B via Elecraft]

A question best asked on the WSJTx support list, where the developers
hang out..

    https://wsjtx.groups.io/g/main

There are plenty of people there using K3's etc.

In any case, it may be more of a Hamlib issue, than WSJTx, and there is
"lots" of work going on at the moment with Hamlib.

[Elecraft] [OT] Birds and DX

[Dave B via Elecraft]

Try a plastic Owl, Hawk, or other dummy predator mounted on the near the
antenna, but in full view..

It too, may detune things a bit if mounted on it, but at least it'll be
there all the time!...

Re: [Elecraft] S6 noise floor?

[Dave B via Elecraft]

Hi Jerry.

The first thing to check, is if the "noise" is from your own stuff, or
outside you immediate control.

You can do that easily, by running the rig from batteries (internal or
external) and turning the house off at the main incoming switch.

If the noise level drop's significantly, then you're in with a fighting
chance of tracking down the source(s).   Go arround unplugging/turning
off "Everything" you can find.

Note the noise level, then turn one at a time back on, and see what is
the main source.

Don't forget anything that is not on a plug-lead.

If there is no change when you turn your house off, then it's something
outside.  A screened room won't help, as of course your antennas need to
be out in the open.

You might want to take a radio and antenna /P to wherever you are
thinking of building a new house, and do a background RFI survey, before
you commit yourself..

Re: [Elecraft] K3S relay noise when using Rx ANT IN port

[Dave B via Elecraft]

I'm somewhat surprised Elecraft don't just flip that relay into the
"protect" position whenever the radio Transmits.

Or at least have a menu option for that relay's behaviour, that defaults
to the "Safe" situation (RX made "Safe" during TX.)  But if you really
do need to, able to be set so the RX automatically protects itself when
it thinks it is needed, as at present.

[Elecraft] CORRECTION! Re: KX3 with KX3 Companion application

[Dave B via Elecraft]

Sorry, just noticed from the KX3 companion website, that I/Q input is
not needed, just the audio output (via an attenuator into the tablet's
mic input) the waterfall it shows is just the recovered AF bandwidth,
not like other tools.   But that will need a 1:2 audio
splitter/attenuator, so you can have phones and tablet connected at the
same time.  (Not difficult to make.)

Quite frankly, a tablet PC, with Fldigi would be my choice to do all
that.  Waterfall, logging, decent decoding, and the ability to run many
different modes, plus fire up WSJTx and the like as an alternative
option to Fldigi.  (But then the fun starts with to-the-second timing...)

73 again.

Re: [Elecraft] Elecraft Digest, Vol 187, Issue 3

[Dave B via Elecraft]

Any persistent lubrication.

"Copper slip" graphite grease, whatever.  Stainless is not ideal in an
outside situation where dirt can over time get into the threads, that
then result in the metal "galling" (partial seizing/self welding) when
you try to move it.

Regular BZP or Galvanised types would be stronger and last longer with
less chance of seizing up, but I'd also use "Copper Slip" or a smear of
graphite loaded grease on them too.   Even plain un-plated steel types
will last OK with such pre-treatment and annual maintenance treatment.

Hi.

The KX3 Utility Rev 1.18.7.3 (the Linux version* at least) does have a

Perhaps there is a later rev utility for your system OS, than you have
at the moment?

Re: [Elecraft] KX4 Features ??

[Dave B via Elecraft]

Speculation mode engaged.

For one thing, if a USB Hub functionality was also built in, you then
only need one physical USB connection between radio and computer, and
you could have full Rig Control, + USB Audio I/O, a well as the usual
KX3 utility functionality (firmware updates etc.)

Ideally, a galvanically isolated USB link to/from the outside world,
preventing ground loops.  Such devices are available, such as (but not
only) :- https://www.analog.com/en/products/ltm2884.html  (Not the
smallest of implementations, just referenced as an example of available
functionality, available now.)

No noisy micro SMPS needed either, as the rig already has it's own
internal power for the internal side, and the PC would power (via the
cable) the "external" side.

From what I recall of the KX3 schematic, the Audio codec chip has plenty
of unused spare audio I/O lines, so at the very least, analogue Audio
I/O could (in principle) be possible with minimal changes to the
physical design (but not firmware I suspect.)  Easy for me to say that,
I don't have to do it.  But that alone would make an excellent rig even
better.

Re: [Elecraft] Windows Update and the K3 USB Audio

[Dave B via Elecraft]

Hi.

You can "fix" regular USB<>Serial devices, to always show up at the same
COM port, when the system (re)starts, or you (re)plug something.   
Plenty of instructions on the interweb, including this which I had a
part in, that seems to work with Windows 10 & earlier.

http://www.w1hkj.com/doku/doku.php?id=howto:taming_the_wild_comport_in_windows

For Linux users, you can use "udev rules" to do the same (and more.)

I have no idea re MAC's, but you could ask about the issue on any of the
*BSD mailing lists.

Re: [Elecraft] Windows Update and the K3 USB Audio

[Dave B via Elecraft]

Re:-

If your radio computers must be connected to the internet, as mine are for DX 
clusters, Club Log, firmware updates, etc., etc., then this may not be a good 
idea, since older systems are targets for malware. When MS stops supplying 
security patches, the situation will become even worse.

Victor 4X6GP 



ALL systems are targets for malware, and crypto currency mining, be
aware of that.

As for security, well, Windows 7 is OK "Now", but after Feb' next year,
as has happened within days of Win2k and XP being cast adrift, some
"new" (previously known to hackers, but unreported to MS) vulnerability
will be leveraged against Win7.   Win 10 (& perhaps 8.x) will be
patched, but 7, ?

Depends on what % of the web is still populated by W7 I guess, MS have
pushed out one or two updates to XP long after they otherwise cast it,
purely due to the severity of the issue, and the damage even a small %
of such population could cause.   The recent RDP issue I think being one
of them.

So long as your border gateway device is secure, and correctly
configured (UPnP disabled) updated and so on, you could survive running
Windows 9x, so long as you never "went anywhere bad" on the 'net, and
that's the problem.

You have in practice, little control where your browser goes.  OK, you
my point it at an otherwise trustworthy site (QRZ, QSL, clublog and so
on.)  But they have adverts on there that are served up by external sites.

Worse, many are animated to catch your eye, and also respond to the
mouse cursor moving across them.  ANYTHING that moves on screen is
running code, and THAT IS where the issue is.  That code can do anything
it wants, as well as what you see it doing.  Someone will probably know
you moved (even unconsciously) your mouse pointer over their add.

Some third party tools ("Ublock Origin" etc) can block many, but not all
of such things.  But many genuine sites that rely on the ad's to provide
revenue to cover running costs, may then block your access to the site
you want.

~ ~ ~

Re your border gateway devices...   Be prepared for some firmware
updates in the near future.  One of the popular embedded OS's used
"VxWorks" has been found to have (at least) 11 critical vulnerabilities,
and this stuff runs in billions of devices world wide, designed to be
interconnected via the web too.

See:- https://www.grc.com/sn/sn-725-notes.pdf  Then scroll down to page
9 or 10 (depending on your reader)

Note too:  New problems for exposed NAS devices, that many people are
unknowingly showing to the world!

[Elecraft] Subject: The ability to send screen shots

[Dave B via Elecraft]

This is a text mode list, so it would I think need more than a casual
change to accommodate images or attachments.

However...  There is nothing to stop you from posting images to your
favourite photo sharing site (such as, but not only photobucket) then
(most importantly) making it publicly accessible, then sharing the link
to that image or page.

That keeps the list traffic down, and still allows people to see what is
being talked about.

Re: [Elecraft] Silent power supply for a K3s

[Dave B via Elecraft]

Easy way out of this mess, if a little expensive...

A big PSU dedicated to the rig(s), implementing "Remote Sensing" so at a
distribution point close to the radio(s) the DC voltage is held
constant, irrespective of the cable length from the PSU.

This power supply should have a proper overload (and over voltage)
protection scheme too, not only to protect itself, but the radio(s)
also.  And safety resistors between + and +s, also between - and -s
terminals.  (Prevents expensive embarrassment, if a sense line fails!)

Then use a smaller PSU for the low power accessories, with suitable fusing.

Any QRO power amp, needing really high current, should have it's own
independent dedicated PSU, again with remote sensing to keep the voltage
at the PA as near constant as it can be, and the resulting high DC
currents, purely between the PA and it's PSU.

Just my way of doing things, to keep the high DC currents out of the RF
cabling.

Google "power supply remote sensing" for more info.

Re: [Elecraft] K4 and Linux Infrastructure

[Dave B via Elecraft]

Hi.

The problem these days, is not only if something is exposed to the www,
but even if it can only be "seen" by other nodes on the same LAN.   Such
as the main shack PC, that probably can reach out to the WWW.  Once
"something" gets into that PC (or your IoT lightbulbs!)  It can at it's
leisure scan your shack (and/or home) LAN, looking for other
nodes/devices to poke at later, after "phoning home" with the details of
what it found.

You all have got your dumb IoT devices (including TV's and PVR's) on a
segregated VLAN haven't you?  No!  You have work to do then!

Also, irrespective of the OS used, one way to reduce the chance of user
induced mayhem, is to boot from a (protected) read only medium, copy the
OS to RAM (for speed) and use another SD card as persistent storage,
with an option during the initial boot (if for example) some combination
of keys are held down, to load the default settings into the "user"
area, as an easy "Factory Reset" feature.

Then, whatever the user does, when (not if) they muck it up, there is an
easy get out of jail free card.

As to the network security issue, the only "secure" network device, is
disconnected, powered off and in a sealed & screened box!  Period.  What
may be regarded as secure "now", in six weeks time could be hacked to
hell and back by script kiddies all over the world.  In truth,
currently, the bad types have the upper hand.

Sadly (as with any OS) a continual surveillance of the ecostructure is
needed, and the inevitable updates.  There are many ways to do that of
course, some easier, and some more "secure" than others.  Security and
convenience are mutually exclusive, sadly.  (In the case of a RO boot
medium, a switch would need to be flipped to allow a (once verified)
image to be flashed onto it, one time, said switch auto resetting once
programmed.)  Or another card shipped in by post, and that's not as
secure as you might think either!

Regarding legitimate use of a LAN/WAN connection.  One would hope(?)
that at the bare minimum:-

The radio control firmware is not run as root.

Incoming ssh requests are ignored/blocked.

In the case ssh connections are allowed, root login by ssh is blocked,
and only pre authorised (by certificate) user(s) are allowed in
(Elecraft themselves for example.)

The use of su and sudo are blocked if anyone does get to a command line
as "a user".  Also browsing the OS software/settings folders is blocked,
should the firmware die, leaving the user at a command line.

Have the radio "reach out" to Elecraft central when needed using OpenVPN
(for example, using the current state of the art security model) to
check for updates (user initiated) or for Elecraft to remote admin,
after telling the user how to initiate that feature..

Any such automatic updates are "staged" within the rig, until they can
be verified as complete, uncorrupted and genuine, before being applied.

Any custom daemon software intended for legitimate remote
control/interface use, should be written in such a way, that any corrupt
or unknown commands (and/or parameters) are ignored, not even returning
any error code to the initiator.  Greatly reducing the ability of it to
be "fuzzed" for vulnerabilities.

Also, . 

Similarly, any code created to allow the radio to control accessories
via the LAN port (PA's ATU's etc) should be created with security in
mind.  Such command & communication links should be encrypted, so only
the intended endpoints can see/use the data.  ESPECIALLY, in the case
that such links traverse the public internet...  (A licence requirement
here in the UK by the way!)

Any built in Digimode software (PSK, RTTY, CW, JT modes etc) should also
be run in a VM, within the radio.  Hopefully preventing any possible
remote takeover issues via that route!  (None that I know of at this
time, but ...)

Trouble with all the above it, it takes */a lot of time and effort/* by
the equipment makers to do, and do right, plus the testing of it all, or
contracting in some qualified penetration-testing types to test it all
for you.  And that cost money.   That, and capable hardware to do all
that, is also not exactly low cost (but is getting lower in cost.)

Also, all the above is not unique to Linux, */all OS's/* have their
issues, just that some are better(or worse) than others.

Effective Security is difficult to make user proof.  Educate the users
first.  If nothing else, listen to the "Security Now" podcasts by your
countrymen.  https://twit.tv/sn  (Another episode later today.) 
Entertaining, and you might get an appreciation of just how much mayhem
is going on out there right now.

Happy Days!

Oh dear Elecraft..

You should not be shipping US power corded equipment to Europe (or I
suspect anywhere else outside the USA!)

If it was purchased through a local dealer, "they" should have removed
the US spec' cord, and replaced it with a EU (or other local) spec'
power cord, and also possibly PAT tested it.  (Electrical safety test,
relating to insulation and safety ground integrity for all exposed
metalwork and connectors.)

Do they also comply with the EU "Low Voltage Directive" in regards to
Power Factor (Line current distortion) vs the power drawn from the
supply I wonder?   If thy just have a transformer/rectifier/capacitor
type supply, the answer will be no.

If using a bought in SMPS, then maybe, but the SMPS makers data will
need to be examined.

Transformer Rectifier Capacitor type PSU's for "non industrial" use are
largely outlawed over here for such high power applications these days.

Regards.

[Elecraft] Subject: Re: Hub4Com

[Dave B via Elecraft]

If it's just a need for one bit of software, to send the same command to
two devices at the same time.  Just parallel wire some connectors together.

One Serial OUTPUT, will usually drive two INPUT's without issue.   All
you need is the TXD wired to two RXD's, and the corresponding
ground/common wire of course.  (And the same baud rate, start/stop bit
and parity settings etc.)

Now, if you want to get data /back/ from BOTH device's, then that's an
entirely different can of worms!

From one, easy.  From both /reliably/, not so, unless you can
/guarantee/ that only one device will respond at any one time and /only/
when you ask it to.

Even then, you'll need at the bare minimum two diodes and a resistor. 
(Note!  That may be troublesome at high baud rates with such a simple
scheme.)

Have Fun. ;-)

Re: [Elecraft] KX3util & XG3util on 64 bit Linux? FIXED

[Dave B via Elecraft]

Right..

Not exactly the usual done thing, answering ones own question, but here
goes...

~ ~ ~

I had previously performed:-

    $ sudo apt-add-architecture i386

as recommended elsewhere.  However that was not enough.

I found I also needed:-

    $ sudo apt install ia32-libs-multiarch

That pulls in a huge number of 32 bit compatibility libraries, and
enables "multi architecture support".

Now, the Elecraft XG3 and KX3 utilities run as advertised on this 64 bit
Linux Mint 19 system.
(Based on Ubuntu 18.04 I believe.)

Well, they work OK, but there is a warning shown when launched from a
command line.

(xg3util:1328): Gtk-WARNING **: 10:56:10.065: Unable to locate theme
engine in module_path: "adwaita",

That's one for the developer to figure out I suspect.  This system uses
the "Cinnamon" desktop.

Note!  The leading $ in the above command line examples, just signifies
that the command was entered into a terminal command line.  "sudo" is
needed to temporarily elevate oneself to "Root" privileges, as what is
needed, needs to be placed deep within the system, where ordinary users
cannot (usually) write to.  (The password it asks for, is your usual
login password.)

Hope the above helps someone else.

FYI:

Using the file command, will show you what sort of executable the
program is.

$ file ./xg3util
./xg3util: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.6.0,
stripped

Using the ldd command:-

$ ldd ./xg3util
    linux-gate.so.1 (0xf7f35000)
    libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xf7f05000)
    libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xf7ee6000)
    libstdc++.so.6 => /usr/lib/i386-linux-gnu/libstdc++.so.6 (0xf7d6)
    libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0xf7c5e000)
    libgcc_s.so.1 => /lib/i386-linux-gnu/libgcc_s.so.1 (0xf7c4)
    libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xf7a64000)
    /lib/ld-linux.so.2 (0xf7f37000)

You can now see the linkages (for example) between libc.so.6 as
requested by the program, it now points at the same name library in the
/lib/i386/i386-linux-gnu/ location.

In both the above examples, those commands were run from a terminal
session, while located in the folder where the xg3util program resides,
hence the preceding ./ before the filename.

Hi.

On Linux Mint 19, 64 bit.

Have the 32 bit compatibility tools installed, but neither the XG3 or
KX3 Utilities will launch, both complaining about

dave@dave-HP-Compaq-8200-Elite-USDT-PC:~/Elecraft/xg3util_1_13_6_4$

To me, it looks like the path's are wrong.

It's late here and the grey cell is fading.   What's the fix?

Thanks.

Re: [Elecraft] WSJT-X Disabling TX INHIBIT on K3S

[Dave B via Elecraft]

I've not checked in detail what PTT inhibit the KX3 has, but I have
tripped it up on one occasion in the past, but I forget how how I
un-tripped it!

Certainly in some circumstances an external "interlock loop" could be
useful to have, or a key switch on the front!

On my TS870s, Menu 27 set to ON, utterly disables the front panel TX and
Tune buttons, and both the Mic PTT, Aux TX line, VOX and the CAT TX command!

It's state is remembered when powered Off too, so is useful if you have
kids (or cats) in the house and when developing custom software that
will use the radio.

(The Aux port TX line needs to be used, so as to route digi-mode audio
from that port to air, and mute the Mic.)

Many Kenwoods also have a "feature" that if the Mic PTT is active when
they are powered up, they will not TX, but locks out the transmit
ability.  Many have been caught out by a faulty Mic that way!

I don't know, but maybe Elecraft have implemented that last one, I've
not tried that on the KX3.  If I remember, I'll try later.

I do know that if you momentarily feed the KX3's Mic jack's PTT line a
+ve voltage (I forget exactly, but somewhere greater than +3V) it will
power up the radio from the OFF state!  Very useful for a QRP remote.  
Once "awake" the PTT line works as normal.   A CAT command is used to
power down the rig when you're done.

[Elecraft] Timekeeping (was Re: CODEC)

[Dave B via Elecraft]

You might as well say, why use an OS that was originally designed to run
on 16 bit hardware.

Like Windows (and I'm /not/ a MS fan)  Meinberg (and others including
NTP/NTPD itself) have moved on along with the times.

It's the NTP protocol handling that's important, not the GUI you see.  
But by all means use a recent implementation as there have been security
(DDoS) issues with some implementations of NTP in the not too distant
past.   But that's only an issue if you plan to make "Your" time,
available to others on the Internet.

There is nothing stopping you from building your own local shack GPS
driven NTP server either.  Use a R'Pi etc.

https://satsignal.eu/ntp/Raspberry-Pi-NTP.html

or

https://robrobinette.com/pi_GPS_PPS_Time_Server.htm

for example.   You can then sync all your shack PC's to the same time,
not needing any external internet, though it's useful for when a GPS RX
fails, or it's power supply...

[Elecraft] Timekeeping (was Re: CODEC)

[Dave B via Elecraft]

In that case, just change the default time server that Windows is trying
to use, to   pool.ntp.org   (works anywhere in the world you have
reliable* internet.)

Or..   north-america.pool.ntp.org   If you're in the USA.

See  https://www.pool.ntp.org/zone/north-america   and  
https://www.ntppool.org/en/use.html

Unless you have a really flaky CPU clock, or some other CPU hogging
issue, Windows own timekeeping service is more than good enough for the
JT modes where you only need to be +/- 1 second or better, so long as
you do not use the highly congested default  time.windows.com (or
whatever) server they set it for by default.

(* Reliable and stable, not necessarily fast, and avoid mobile internet,
the latency is too variable.)

Re: [Elecraft] CODEC

[Dave B via Elecraft]

You could always create something in Python, to have the computer read
and save the current rig settings you will alter, then invoke whatever
digimode software you use, then restore those radio settings to "normal"
after you've done.

There's lots of info out there regarding how to use serial ports etc
from within Python.  For rigs with a LAN port, it's even easier!  That,
and the excellent Elecraft user/programming manual are all you need,
other than time.

Python is an easy language to learn, OK, so not as simple as "Basic",
but simple enough for first timers, and capable enough for more
experienced types.

Works in Windows and Linux (including the Pi of course) and probably on
Mac's too.   There are a host of developer tools out there, but a good
cross platform editor that is Python (and other language) syntax aware
editor, is "Geany".   Very good.

[Elecraft] Subject: Re: KPA1500 - Static IPv4 address

[Dave B via Elecraft]

A better way, perhaps...

Leave DHCP enabled in the PA and any other equipment, but make a written
note of the PA's LAN port MAC address.  (And that of any other LAN
connected device you have.)

In your router (or other DHCP providing gadget) look in it's setup for
"address reservation" or similar menu item (or RTFM to find it)

In there you can usually identify all currently connected devices, if
not by name (if the device reports that) but by MAC address, and you can
then tell the router (or whatever) to always assign the same IP address
to that MAC address.

(If the device is not connected, then that IP address is not assigned to
anything else, as it is reserved for that MAC address alone.)

In your PC (whatever type) you can also edit the "hosts file" to assign
a known IP address to a "name", making things even easier.   Lot's on
the interweb about that.  (On Windows, you will need Admin rights to
write to/save that file, on Mac/Linux you'll need Root privileges, so
take care.   Make a pre-edit backup, just in case!)

Job done.

I (and many others) do this, for such items as NAS servers, dedicated
special purpose PC's, printers, other servers, Raspbery Pi's (used as
VPN endpoints) IoT and and LAN to Serial port devices.   It all "just
works" seamlessly.

But, do keep written notes as to what you did, as you will need that
sometime in the future.

Hint!  If you don't want to mess with your ISP's supplied router, there
is nothing whatsoever preventing you from using something like the old
Linksys routers as dedicated "Shack" routers, that you have 100% full
control of.  If at some point your ISP changes, nothing in the shack
needs to change, as that box is just another device on the new router's
LAN side.

Many pre-used domestic routers can be used for this sort of thing, and
just about all commercial SoHo routers too.  Especially those that can
take the WAN side by a network port, not just cable or xDSL.

Lastly, I don't know what Elecraft use for their LAN ports, but if they
are the common Lantronix embedded devices, then Lantronix have a "device
installer" program, that will reach out find and identify the IP address
of all such devices on your LAN.  You'll still need to know the device's
MAC address though.  Find it on their website. (Google will tell you where.)

That's a Windows tool, there are other (somewhat advanced) ways of doing
the same from Linux, I have no knowledge of if that can be done with a Mac.

Re: [Elecraft] loss of RX sensitivity

[Dave B via Elecraft]

No, BNC's and N's do not inter-mate, not without damage.

Yes, you can push a N plug into a BNC socket, but the BNC socket will be
permanently damaged if you push hard enough for it not to fall out
unexpectedly.  Plus the mismatch will be bad.  But in an emergency?

Yes, the dimensions of the actual RF connector interface are similar,
but there is a major difference in the dielectric arrangements.

N's are "weather resistant" (some more so than others) but not "water
proof".  BNC's of course are neither.  (And neither are SO239/PL259's!)

Re: [Elecraft] loss of RX sensitivity

[Dave B via Elecraft]

Hi Jim.

Mostly, N connectors, BNC's, TNC's, SC and 7-16's.  And for the big
stuff, EIA flange connectors.  Plus some other weird stuff.  (3 lug
BNC's and such, to prevent the "wrong connection".)    The odd
appearance of the C connector on some US kit too.   Some "Spinner" 'BN'
series connectors to, also often seen in the European Broadcast industry
and some military.

A lot of US equipment also still use the various unique to the US
connectors, often seen on big Bird loads etc.  Not so common over hear.

That based on what I've seen on kit "being tested" at customers sites
over the last 28 years.

The only UHF series connector commercially used, that I've personally
seen in that time frame is on a very old design of screened room weld
crack detector, and it's a nightmare to use as it's always working loose.

To Charlie.

The threads have no part to play in the RF path on a UHF connector, it's
all down to the two outer mating faces being pressed together.  The
older (so called) MIL spec types, that had all the castelations at that
point were *MUCH* better because of it, as they sort of interlocked and
made a much better contact due to the metal to metal force
multiplication that results..   They also tended not to rotate relative
to each other so the retaining ring stayed tight.  Basic mechanical
design feature, missing on the modern versions, where the two parts can
rotate, even when the ring is (allegedly) tight.

The modern stuff with the 4 slots on the socket, and two bumps on the
plug, are just utter crap.  (Built down to a cost.)

I'm amazed that no maker has innovated gone back to the original design,
and fitted a crinkle spring washer behind the locking ring, so that
contact pressure can be maintained, and also helping to keep the threads
from working loose when subject to vibration...

But even then, they'd still only be of any practical use below 100MHz
due to the impedance mismatch issue.   (Originally for use below 30MHz.)

https://en.wikipedia.org/wiki/UHF_connector

Stick with BNC's, N's and if you have too, 7-16's.  They are all easy to
fit to cable with practice, no special tools needed unless you insist on
the crimp types, and then you *MUST* have the correct tooling for that
particular make of connector.

The pressure gland fitting types, are also easy to remove, clean up and
re-fit if a cable becomes damaged.

All it takes is some practice.  Buy some surplus ex-military patch
leads, and practice removing and refitting them.  After a few of each it
becomes very easy.

73.

Re: [Elecraft] loss of RX sensitivity

[Dave B via Elecraft]

Wunder, I'll second you on that!

Of all the 1000's of RF connectors I've assembled and used over the
years for my own hobby and at work.  The venerable "UHF" series have
always proved to be the nastiest most unreliable types ever.  Period.

All my own personal radio kit, either get's them replaced (Sadly, not
always an easy job) with a N or BNC (in one case, a TNC.)  Or a BNC (or
N) adapter is securely fitted as a permanent fixture (including LocTite
on the threads, in mobile/portable situations!)

I also use BNC's at HF, as we do at work.   They can happily carry well
over 150W at up to 220MHz even in the presence of some very bad VSWR's
(6:1 or higher.)  Assemble them correctly and look after them
physically, and they will last a lifetime.

The UHF series are just plain unreliable.  It is no surprise that the
military (NATO) don't use them any more.

Re: [Elecraft] Decoding the Serial Output from a KX3

[Dave B via Elecraft]

Top marks Sir.

It's the extra understanding of how things work, you get when doing
projects like that.   Most important for the times when suddenly things
stop working, one has then the knowledge and skill to diagnose, debug
and repair.

A refreshing change to the "I use this device from that company" one so
often sees these days.

Plus, the Elecraft rigs using a Kenwood like protocol, it'd be easy to
massage the code to accommodate other Kenwood like rigs, etc too.

Well done.   This is what Amateur Radio is all about.  Learning stuff!

I have used an arduino to decode the serial output from a KX3 and 
develop the band signals used to switch a KPA500 linear. The interface 
has been working for many weeks. The interface may have utility with 
other linear amplifiers as well.
If anyone is interested in details, let me know.

Re: [Elecraft] Elecraft SW (and wsjt-x) on Ubuntu 18.04 anyone?

[Dave B via Elecraft]

The KX3util, you'll need to get/install curl, else it wont be able to
get updates etc.  (It doesn’t check when you launch it, it just fails to
communicate with Elecraft's server when it tries.)

The utility itself, you just extract the executable to a folder of your
choice, there is no "install" as such.  Well, the last time I looked!

Re WSJT-X.  Should be easy, just pull the appropriate (32/64 bit) .deb
from:-

    http://physics.princeton.edu/pulsar/K1JT/wsjtx.html       (Scroll down)

And install it that way, the system will/should pull any needed
dependencies (Qt5 etc) you may not yet have.

Unless you want to build from source, then follow the usual links to
source forge, but expect to have to also install several lib
dependencies, even then you'll probably need to sign up to the
developers mail list to get it to build correctly on your system. 
(Devil in the detail etc.)

I'm running the Elecraft tools on Mint 17 and 18, and WSJT-X on Mint
18.  (All 32 bit) Ubuntu derivatives of course.

The latest WSJTX tools wont run on Mint 17, as QT5 does not support
Ubuntu 14.04, that Mint 17 is based on.

~ ~ ~

You can also find the official 32 bit Windows version there too, if
anyone needs.

Re: [Elecraft] Elecraft Digest, Vol 171, Issue 2

[Dave B via Elecraft]

Hi.

Personally, I think what might be needed is some co-ordination on the
lower VHF bands, to initiate something like the HF IBP system, where one
frequency is used in turn by a collection of beacons.  (Multiple
frequencies could still be used, but accommodating multiple beacons per
frequency.)

Using a Next Generation Beacon mode, you get not only human readable CW,
but machine readable modes so you can leave a PC monitoring to build an
appreciation of propagation to/from your location.

See:      http://www.ncdxf.org/pages/beacons.html
     http://www.ncdxf.org/beacon/beaconschedule.html

Also, for other idea's:
            http://www.rudius.net/oz2m/ngnb/index.htm
and:     http://www.gb3vhf.co.uk/GB3VHFReceiving.html

for some examples.

No affiliation, just idea's, to perhaps avoid many beacons all QRM'ing
each other.

Re: [Elecraft] KX3 Utility Linux version

[Dave B via Elecraft]

Don't let a few idiots put you off Linux.

Look into the linux...@groups.io mailing list (the home of Fldigi etc)
Lots of GOOD help on there, by many who remember our initial frustration
with it all.  (Some Elecraft users there too.)

As to one OS vs another.  Linux is different, that is all.

Do any of you remember when you first started using Windows or Mac*?
I'll bet that was just as frustrating and confusing then, as if you
expect to "just jump in, and survive" with Linux (or BSD, or MacOS)
these days.

(* Has to be said, that back in the Steve Jobs days, the UI was truly a
work of art, you didn't need instructions.  Since his sad demise, it's
all gone a bit Pete Tong.)

As others have said, it is possible to have a PC that will boot it's
original OS (Windows or Mac) or one or more versions of Linux (or any
other OS) so you can choose at boot time what you want.

Yes, there are several well known Ham Radio programs that have no
"Direct equivalent" Linux version, but there is other equaly good
software native to Linux that will do the same job.  Mostly.

There are also some that have no equivalent, or even anything close
(sadly.)   Some of them will run under WINE, some wont.

But, unless you use them all the time every day, you won't need them
most of the time.  (Thinking here of Motorola DMR programming software
as an example.)  In such cases, just boot into Windows, get that job
done, then if needed reboot back into Linux (or whatever) and carry on.

If you want to just get your toes wet, without risk of corrupting or
bricking your main PC, get another, or even a Raspberry Pi, to
experiment on.  The Pi's are good, as the whole OS etc fits on one SD
card.  If you mess it up, it's trivial to wipe and start over.

The latest Pi's are really good and powerful machines too, much more
than you'd expect from something of it's size, and at the price, can't
be beat.

Dont give up.  Keep moving.  Explore the pre-built packages first,
before trying to learn how to compile stuf from source.

But when ready, get onto the Fldigi wiki, and follow the build
instructions there, to build and install the latest Fldigi etc.
http://www.w1hkj.com/doku/doku.php?id=start

If needed, ask on linuxham.io for assistance, and it will be given.

73.

Dave G0WBX.

The 32bit code on 64bit system problem varies by OS.  Windows(64)
generally has good support for 32 bit applications.  (Most of the more
esoteric background system tools are 32 bit code anyway, some are still
virtually the same as those developed for Windows 2000, or even NT!)

But these days MS has no support for 16 bit software, such as Windows
3.xx code etc (not exactly surprising, but the old Win3x "Terminal"
program is still quick and easy to use, for example, on an old XP box.)
  Windows 32 bit systems, XP and earlier, fully support the old Win3x
software, and many DOS programs too.   (Vista and later dropped 16 bit
support, even on the command line.)

In the Linux world, it's utterly different.  From my personal
experience, a pure 64 bit system will not run any 32 bit code "as is",
unless you hunt down and load a sort of compatibility layer.   Much as
in the later days of Windows 3.xx, you'd use a 32 bit compatibility
tool, to run some 32 bit code on a 16 bit system!   Some systems come
with that already, but it needs enabling.

So, if you go to a 64 bit Linux, unless all the programs you want are
freely available in that OS's 64 bit flavours, you'll have to compile
them yourself.  And that too, can be troublesome for some older (and not
so old) Ham software, where the original author has "handed off" support
to the "community."   Also, some of the compilation tools that a lot of
the older (but still very good) code needs so you can build it, have not
yet been updated to "64 bitness" themselves.

Plus, as before, though "64 bit" CPU's have been around for a long time
now, many of the class of machine that most of us would "recycle" (Ex
Vista era or later laptops etc) and put Linux on, other than the
internals of the CPU, are in truth 32 bit machines, and as such will
have memory addressing issues above 4Gig.

Even ex XP machines, running 32 bit versions of Lubuntu, LinuxLite, or
Puppy Linux, can have very useful roles in a ham shack, for (other than
time) next to zero cost.

If however, you want to edit/mix real-time HD video and audio on a PC. 
Then, a fast 64 bit system will probably be needed.   The other "maybe"
need, is if you run a pure SDR based station, and need to run various
digimodes all on the same PC, with multiple screens and I/O systems.  
But I know of other people already doing all that on 32 bit Linux
systems just fine anyway.  (Once they find out how to make it all work
and play nice.)

Plus as before, the K3/KX3 utility, only communicates to the radio over
an 8 bit link, & that is not in the MBPS range.

I have no experience of Apple products, other than on odd occasions
having to reconfigure the XYL's iPad WiFi settings.

73.

Dave G0WBX/G8KBV (Who does use Windows 7 Pro 64 bit at work, but I'm 95%
Linux at home now.)

PS:
The fix for this, is to release the K3/KX3 utility sources into the
public domain.   Then if you want, you can compile it on a 32, 64 bit
(or other) system where a compatible compiler exists.   Any Elecraft
"secret sauce" could probably be reverse engineered from the existing
tool today, by recording and examining the data passing between the rig
and utility, for known tasks.  (I'm thinking of the firmware update
procedure etc, all the other stuff is documented in the manuals.)

Speak for yourself Sir.

There are 100's of 1000's of us out here with older hardware, happily
running current 32 bit os's such as Mint 18.x 32 bit, and all works fine.

Why follow the MS/Apple flock of sheep, just because they are moving to
64 bit systems?

There is no advantage for 99.9% of users, to move to a 64 bit OS,
whatever the flavor.

The hardware wont support the oft quoted 10's of GB of RAM (even if the
CPU might.)   Plus, for the ram we've got, with the system maxed out (be
that 4, 8, 12 or more GB) any given app takes twice the space compared
to 32 bit code, same with the storage.

It's marketing BS foisted on us by the likes of MS and that Fruit company.

Plus you then have to load 32 bit compatibility tools in some OS's, to
carry on running the software you have!

So why bother...

As to the K3/KX3 utility, well, the transfer to the radio is over an 8
bit wide path.  Need I say more.

Google's automated translation system does a very good job with that site.

Just copy that link in the left side box at :-  https://translate.google.com

Let it autodetect the source language (it seems to detect German) and
leave the default "English" set above the right side box, then click on
the link in the RIGHT side box, where upon, you'll go to a translated

Even the menu links on the right side of the pages are translated, as
are the contents of said pages.

Re: [Elecraft] wsjtx-x drops receive signal and stops txing, randomly

[Dave B via Elecraft]

Bet that's a Mac being used!  They do seem to be more prone to this sort
of thing, than other "lower class" of computing devices.

It's sadly all too common an issue, and no one yet I think has found the
definitive answer as to why it happens, or how!

Unless you suddenly find that there is no RX immediately after a
successful TX, in which case I'd suspect RFI getting into the
PC/Sound-card interface.

Check your cables are secure, and there are no "pin-1" problems
anywhere.   Keep the "area" of any ground loops to a minimum too.

Check on the JT mode forum's etc.   But you'll need to detail the
make/model of PC, sound-card (if external) Radio.  Also the OS and
version used, plus exact version of the software and perhaps sound-card
drivers, for anyone to even begin to tie this down.

Re: [Elecraft] Operation of K Line Over LAN (Tom Richardson)

[Dave B via Elecraft]

That'll be to the PTT line to power up the KX3, not the Mic input! 
(Care needed.)

Ser2Net (and similar Linux tools) are very good I find.

It's also possible to use Grig to control a remote radio, via Hamlib on
the PC (or Pi) at the radio.   Assuming of course, that the
implementation for your radio in Hamlib is complete and (relatively) bug
free.   I have controlled my TS870 that way from one side of the shack
to the other.   There does seem to be quite a lot of LAN chatter though
doing that, making it a less than pleasant experience if doing that over
the interweb.

For audio over LAN on Linux, I've settled on a very lightweight tool
"Seren".

    http://holdenc.altervista.org/seren/

Just take note of what you need to do, to run it on a Pi.

It works *Very* well, can provide excellent audio quality, and is true
point to point, unlike the behemoth bloat of Skype.

(I keep meaning to investigate Seren's text messaging facility, to use
as a simple rig control path too.  It's all open source, but I have too
many "Round Tuits" to shuffle as it is.)

Easy when done correctly, & NOT by using a SO239 socket on the output!

That thing should have a 7-16 connector at least on the output.

I don't see any mention of any automatic protection against high VSWR or
other woes that'd damage the tube and/or tuning networks.

Re: [Elecraft] 48 volt PS

[Dave B via Elecraft]

Ted.

Best to box the PSU and silence the fan with sound deadening material
without affecting airflow.  In effect, creating a "silencer" for the air
inlet, and maybe outlet.

For that sort of power level 500W and above, and the small size of those
PSU's, the cooling is critical for a long life.  So, the gutsy but noisy
fan is there for a reason.   Replace it with a quieter one if you must,
but don't compromise the airflow.

As to RFI.  All SMPS's create it, some more than others, by design.  It
can be filtered of course, but to do that properly will also cost a fair
bit.

Voltage divider?  Just use a dedicated 12 (13.8V) PSU for the K3.  You
then have redundancy for when the 48V supply quits at some point.   If
you must, one of the common "Telecom" DC/DC converters, (48 to 15V, and
a linear post reg) to get your K3 supply.

But, make sure you know which side of any such DC/DC converter is
common, if not isolated.  You may be (unpleasantly) surprised!

Remember the KISS principle.

Re: [Elecraft] KX3 clock & battery. (Was KX3 clock will not, set from KX3 utility)

[Dave B via Elecraft]

Hi Bob.

That's not what I was asking.    What I would like to know, is:-

Should the clock use External power (if present) instead of the
installed batteries (whatever their type might be) when the radio is in
the "OFF" state (i.e. Not in use.)

If I remove the cell's, then they retain their charge for many weeks
without problem.  In the radio, they will drain to a low value after a
couple of weeks.  Even if it is still hooked to the always on, shack DC
power system.

Is this a "Feature" or "Fault/Bug" ?

73.

Dave G0WBX.

PS:    I have had no trouble setting the clock from the utility program,
running Windows(7) or Linux(Mint).

[Elecraft] KX3 clock & battery. (Was KX3 clock will not set from KX3 utility)

[Dave B via Elecraft]

Hi All.

Regarding the KX3's clock and battery functions.

Am I right in recalling that the clock will run from External power, not
pulling the battery down, if external power is available when the rig is
turned off?

If so, mine has an issue, as even with 24/7 external power (13.5V) when
the rig is "Off", it will drain the internal batteries down to near zero!

I have to periodically power the rig (if not regularly used) and
recharge the batteries as a result.

Is this "normal", or ???

What version Fldigi, Flrig and Hamlib?   Also, what exact OS on the Pi?

Did you build Fldigi/Flrig from sources, or pulled from a repository?  
Sadly, the repo' versions are often out of date.

The best place to ask for help, would be the LinuxHam list on Groups.io.

Re: [Elecraft] Operating FT8 portable with KX3 - GPS time sync question

[Dave B via Elecraft]

That'd be found at:-

    http://www.maniaradio.it/en/bkttimesync.html

Looks good though not tried it myself.   (Always try and get stuff like
that, from the author's own site, not from some arbitrary download page,
where it can have "other stuff" you definitely do not want, bundled with
the download.)

If using the network option, I'd suggest you use the address:-

    pool.ntp.org    (or    north-america.pool.ntp.org in the US.)

As the target server.   That will get you the nearest (network wise)
server to you. Keep well away from time.windows.com (or whatever) as
it is so congested as to be useless for these needs.


If you want your own local hardware NTP server, for example if your
internet connection is at all "flaky", or you're restricted to mobile or
satellite internet, or you have multiple PC's that need to stay in sync,
then see David Taylor's (GM8ARV) pages at:-

    http://www.satsignal.eu/ntp/index.html

LOTS of good info and instructions there to do what you need, and mostly
for low cost, other than time to learn how to, and do it.


If you've $'s to spare and want something that "just works" out of the
box, then...

Not cheap, but very good.   For those in RV's or afloat, best left
running 24/7   Job Done.

If you have one of them in the shack at home, then you can contribute to
the NTP Pool project too, with care, but your internet connection may
get "hammered" as a result by incoming time requests.

[Elecraft] OT: LED Light Bulbs

[Dave B via Elecraft]

Hi.

A lot of the LED QRM issues, are caused by the PSU, or "Electronic
Ballast" dropping into a discontinuous conduction mode within it's SMPS
when low voltage halogen lamps are substituted with LED types.  Change
the "Ballast" or re-fit enough Halogen types to keep it happy (and quiet!)

    It's also worth noting, that the EMC regs for unwanted emissions from
electrical/electronic equipment, is designed to protect Broadcast
services, where signal levels are often several 10's of dB greater than
those that we are interested in.

    So, it is quite possible for a fully approved gadget to pass all the
required emissions tests, and still create mayhem on HF in particular.
Also, in the EMC world, for commercial products (sold to the likes of
us) it is assumed that nothing "radiates" directly from itself, as it is
too small a fraction of a wavelength, so only conducted tests are done,
and on artificially loaded leads and cables.

Of course, add such things as long speaker leads, other gadgets, and you
have a situation where a collection of fully approved pieces of (for
example) domestic cable/satellite TV equipment, where each on it's own
is fine, when used together cause trouble.

It's what happens when committees create test spec's.That and
commercial pressure to go the TCF route (Technical Construction File)
where a technical appraisal is done on the design, resulting in a
statement that it is believed no problem will ensue, and again, the
product itself is never tested in practice.  Cost saving pure and simple.

Then you also get creative installers who adapt and modify things,
causing trouble, for example using unscreened leads between a variable
frequency drive inverter, and the motor it powers, purely because
screened power cable is expensive.  Or, they don't correctly ground the
shield rendering it useless.

Similarly, some of the modern LED based traffic signals, should have
screened cables, but don't, purely because of the cost of replacing the
old cabling with new.

And we haven't even touched VDSL and G.Fast used for broadband
connections from fibre enabled cabinets, and the noise they can produce,
or in house Power Line Networking.

Have Fun.

Dave G0WBX.

Re: [Elecraft] Elecraft Digest, Vol 162, Issue 8

[Dave B via Elecraft]

Hi.

I haven’t seen "Kent's instructions", but running the radio -ve power
lead direct to the battery when the radio also has a "Ground" at the
antenna, could result in the destruction of the radio and/or antenna
cable, if the battery ground strap to the vehicle frame goes bad.   
That is not so uncommon as you might think, even on modern vehicles.

Think about where the engine starter current (and alternator produced
charging current) ideally flows, and where it will try to go, if that
ground strap is at all compromised (usually by corrosion, but could be
less than well re-fitted after some maintenance work.)  Meanwhile, you
have provided another battery ground route via your prized radio, and
antenna cable.

The rig -ve lead to be safe, should go to the vehicle frame to prevent
such disaster, NOT directly to the battery -ve terminal.

I've seen a simple CB radio explode under those circumstances and burn
out the car interior.  (I was involved in helping put out that fire with
portable extinguishers that were available.)

I've also personally experience a vehicle electrical fire while driving
(not radio related) and it's not pleasant in any way!...

If you *Must* wire the radio -ve power lead direct to the vehicle
battery (a temporary install for Emcom etc) include a fuse in that -ve
lead, and also make sure that the ground path via the radio and antenna
etc, can take the fault current without damage before that fuse blows!

This is not an EMC/RFI problem, it is a fire safety issue.

Note too, that many modern vehicles incorporate a form of regenerative
braking using the alternator to provide more retardation when you lift
off the throttle at speed.   That can (does) raise the battery voltage
quite a bit, some not so modern (but expensive to repair/replace) radio
kit might object to that.

Also, for that very reason, the battery is rarely charged to more than
about 70% of it's ultimate capacity, to provide "space" for such regen'
braking action generated energy.

It is unlikely that current vehicle build principles are that different
between the US and UK (or rest of the world for that matter) in this
respect.

Stay safe.

73.

Dave G0WBX.

antenna to the feeder at the feed point?

All your doing is adding extra loss to both the TX and RX path.

If the match (indicated by VSWR at the rig end of things) is changing
during the 15 second FT8 transmission period, that could be stressing a
PA and or PSU, and you're hearing an over-temp warning from something,
if that's what it is.

Either case, the cause of the wandering VSWR (if that is it) or the lack
of cooing to the PA/PSU needs sorting out.

Lastly, most people running JT (and other digi) modes, don't run the rig
at full power, but between 25 and 50%.  50W is half an S point down on
100W.  Those that do run QRO on those modes, do so with a "Large" PA,
also under run, to keep it very linear (for the modes that need it)
and/or within it's dissipation/duty cycle ratings.

Re: [Elecraft] KX2 and Omnirig ...

[Dave B via Elecraft]

I did that some time ago for my IC-R70, with a custom 4 bit to serial
interface I built, for use with Faros.

It's not difficult, you just have to learn one thing at a time.

An extra serial port (or comOcom) and dumb terminal, so you can
"pretend" to be a radio, and see what OmniRig sends, and what it does
when you send stuff back to it, is very useful.

If there is a K3/KX3 file (I don't know if there is, it's been a while)
look at that for examples, in conjunction with the relevant manuals.

Re: [Elecraft] Remote Operating Time Sync

Really?

Remote operating (as in remote from civilization) is a common usage for
a lot of Elecrafters, so it's highly relevant.

There are subjects way more off topic that run on this list, often for
days/weeks.  You don't moderate them it seems.

Re: [Elecraft] Remote Operating Time Sync

[Dave B via Elecraft]

Because some modes start a transmission on a UTC minute boundary, +- a
second(ish)

The RX software records for a fixed length of time, then examines the
recording to extract the data.

If a transmission starts late or early by too much, the data wont be
decoded.

Re: [Elecraft] Seeking input on KPA1500 station

[Dave B via Elecraft]

Unless you have some of the popular AV/AM software packages running,
that will actively prevent such things.

Don't ask how I know, but we have LAN equipped kit at work, where sadly
due to the AV/AM security software that we have no visibility into, it
intercepts and blocks many LAN protocols and such, that it doesn't know
about.

We have to get IP addresses white listed for them to work, and even then
there are issues.It's easier to use an old PC that has been stripped
of all such nonsense, we just make sure it's never used on the office
LAN itself these days.

That, and if there is a LAN port, you usually need a way to control it's
settings (IP address, Mask, default gateway etc) else you need to use
RARP to find it's IP address from it's MAC address.   As per the popular
(and very good) Lantronix product line.   But finding an AV/AM package
that will not scream blue murder when it sees RARP being used is another
stumbling block.

Then, there are the potential security issues.  How many LAN equipped
bits of kit, have had their IP stack fully vetted and tested to behave
correctly under all situations, plus the products own firmware needs to
be written with security in mind.

There's enough chaos already from consumer IoT things, from light bulbs
to TV/PVR boxes, we don't want similar nonsense in the shack, nor want
Elecraft to become yet another IoT bot target.   (Google "mirai botnet"
for an example.)

RS232 works, & is difficult to remotely hijack for malicious purposes.  
USB connectivity works too (often emulating legacy com ports etc) and is
easy to implement.   There is nothing "Wrong" with LAN ports for control
and I/O etc, but in this day and age, it has to be done perfectly, or
not at all.  And doing that is not trivial!

Plus, any "PC software" will need to be cross platform too.  NOT just
Windoze.   (A Java app perhaps?)   Or, fully disclose and publish the
protocol used by the "device" so the rest of us can use it.

Plus, will users who don't even understand simple serial port settings
even get their heads around LAN address settings and such, plus some
people will then want WiFi because they don't like wired LAN systems.  
Where do you stop?

Oh, and EMC issues.  QRO RF and LAN systems often don't co-exist well,
also LAN cables can, and often do leak QRM, so you'll be needing STP
cables, not exactly low cost.  Again, I know this from first hand
experience, at work and play!

Why not use Optical fibre links, and simple RS232 like
commands/responses.  RF proof, no radiated EMI, no ground loop issues,
low cost, and 99% of all the needed code probably already exists.  
Ready made cables and I/O ports exist (Toslink among others, good enough
for the golden ears brigade, so...)

Just my take on it.

Jim.

As you have experience with a Pi, with the addition of a GPS RX, you can
make yourself a very good GPSD NTP server using that.  Then, just hook
that to the PC(s) that need time sync, by LAN or portable WiFi access point.

Re: [Elecraft] Remote Operating Time Sync

[Dave B via Elecraft]

Hi.

WSJT-X is not that critical, you only need to be within a second (or two
at most) of UTC, & you can easily get well within +- 1 second with mk 1
finger and a call to the speaking clock, or listening to a broadcast
time signal.  Modern PC's don't drift that significantly over a few
hours (unless they have other problems) so that should be more than good
enough.


NTP sync'ing via mobile internet though possible, is often less than
great if it does work, some carriers block the use of that sort of
thing  But if there is no other choice, needs must.  But, rather than
use one specific time source (time.apple.com)   Try using  
pool.ntp.org   or  north-america.pool.ntp.org   if you are in the US
etc.   (http://www.pool.ntp.org/en/ Has lots of good information.)

That's a collection of independent time servers and the load is shared
between them, so they don’t get saturated like services like Apple (or
Microsoft) often suffer, providing a poor service as a result.   You may
find your mobile carrier has a NTP server you could use, but finding out
about it might be a struggle.

The phone's own time is fairly rigidly controlled, so just watching the
clock on that counting up to a minute, while finger is poised to accept
the next minutes time into the PC is also plenty good enough for the JT
modes.

Other solutions, depending on the accuracy wanted, revolve around the
use of a GPS receiver connected to the computer, and some time syncing
software that can use that.  There are many such programs for MS and
Linux, I don't know about Apple stuff, but Mac's run a highly customised
version of BSD, and there are similar programs for that OS, so...  
(Note, that they are not for the feint of heart to get installed
correctly due to the permissions needed.)

Any of those, you should get within a few ms of UTC easily.  Using a
specialist "timing" GPS receivers, and software that can use the PPS
signal (NTPD for example on 'nix, and Meinberg on Windows) to
continually monitor and correct the computers time, then you can get
within single figure microseconds of UTC (Using a real serial or
parallel port, not USB based.)  But that’s mega overkill for any of the
JT modes, but does have it's uses in propagation research and monitoring.

Lastly, don't get overly concerned about it all, else you'll be signing
up for the Time Nuts mailing list!

Sadly, it will never work natively on a RPi as things are now.

The program is compiled for use on an X86 CPU, so even if the RPi had
WINE (and I doubt if that would run anyway) any Windows program would
fail due to the CPU architecture differences.

The Linux (and OSx) versions of the KX* utilities likewise are also
compiled only for X86 processors.

Lot's has been discussed on this list about this in the past, but
Elecraft and the software authors do not want to make the jump to the
Pi, or make the code open source so we could build it ourselves.  
Frankly, that's a crying shame, as it would be relatively trivial to
build the Linux version on the Pi, unless they are using some "secret"
third party libraries internally.

Running Qemu (or VBox etc) isn't going to help either, it they don't
emulate the X86 CPU as far as I know.

The exagear X86 emulator looks interesting, but I've not seen that
before or tried it.

Looking at their website, the cheapest version is only some £11 (UKP)
but emulates a Debian8 system, so you'll still be in Linux, but the
Linux versions of the util's should then work I suspect...

I run the KX3 and XG3 utilities on Mint (on a X86 laptop) and that's
based on Ubuntu, that is in turn based on Debian.  They work very well.

Hi.

Take care with the levels...

The I/Q output from the KX3 is a stereo feed at "Line" level.  (But is
still useful as a mono feed at times, especially if you want the speaker
to be active too, else you'll need to make a "Y" cable from the phones
jack, to serve both the PC's input, and an external speaker or phones.)

The 'phones' output from the KX3 is even higher level, and is also a
stereo feed.

The "Mic" input of a PC is very low level.

So, you'll need at least a simple two resistor attenuator between rig
and PC, so as not to overload the PC, and keep the RX noise level down
(as seen by the PC)   I use a rough value of some 20 to 30dB, depending
what parts I have about.

The source impedance of the KX3 is fairly low (Ohms) and the load
impedance of the PC will be fairly high (kOhms) making the needed
calculations easier.


Similarly, the 'headphone' output from the PC will be a fairly high
level, while the Mic input to the KX3 again is a very low level, so
again you'll need a simple resistive attenuator between the two.
And again, the PC output is a LowZ and the input to the KX3 is a
High(ish)Z, again, simple calculations.
Also turn OFF the Mic Bias option in the KX3 menu.

Just make sure the resistor values used swamp the actual source and load
impedances, this is audio frequency signals, so no need to "match" the
source to the cable to the load etc.

Run the PC's output at a relatively high level, but not into distortion
(test with headphones, so as to swamp any spurious PC related noises.)  

Use the rig's mic gain control to get an ALC level of 4 bars, with the
5th flickering when transmitting, and use the RF Power control to set
the TX power level.  (Use "Data A" mode, so the rig turns off any TX EQ
you may have set for your voice.)

If you find you have to have a very low mic gain, and it's a very coarse
adjustment, then you need more attenuation between the PC and Radio.  
Turning down the PC's output level can help, but then any spurious
noises become significant elsewhere in the audio passband, hence it's
best to run the PC at a high(ish) level, and attenuate it all down to
suit the mic input, but in a way that gives you decent and fine control
of the mic gain.

Likewise, you should see a more or less flat frequency response in your
digimode (or whatever) software when just RX noise is present.

Similarly, if you find you have the PC's mic gain set very low, AND the
Radio's output (volume) set low, you need more attenuation between radio
and PC.

A request please.
Check your PC is not set to make bings and burp etc noises by default
from the internal sound card if that is what you use.Most external
(USB type) sound cards are "quieter" (noise wise) than most PC internal
cards, and also allow you to keep whatever OS related noises you want on
the internal system, keeping them away from the radio.

It takes a little juggling of levels etc, but you can get a very good
results this way.

Oh they did use some big antennas too, for EME and MS etc.  If you read

There are already Linux versions of at least the KX3 and XG3 utilities,
they work well, but are still closed source.

Those (and similar) utilities could just as well be created as Java
applications, then they'll run anywhere there is a working JRE  (even on
a Raspberry Pi or similar.)  If the authors vehemently want to keep the
source closed.

The APRS software YAAC is such an application, and works very well on
many different platforms, serial ports included.  The most excellent
SimSmith RF design software too, is another great example of the use of
Java for cross-platform support.

Java is NOT the same as JavaScript that browsers use.   Though it can be
invoked from a browser (and that is where a lot of the trouble comes
from) you can prevent that in the Java control applet and turn off any
ability for it to be even seen as present by a browser.

Agreed, but it is the importers responsibility to ensure that it is
either supplied with the correct regional power cord, or supply one
themselves.

Many US vendors get it right, but just as many don't seem to care, or
even know that things are different outside of CONUS.

Adapters supplied with "new" products are AFIK not permitted, though it
often happens.   The problem there, is the quality and safety of such
adapters is often poor.   (Often low cost brittle plastic things from
the Far East.)

In this case, as the PSU is intended to be used with a device that has
exposed metallic parts connected to one side of the DC lead, I suspect
(I admit that I do not know for sure) that the AC input to that PSU
should include a safety ground, connected to (among other things) the
transformer inter-winding shield.

It's been a very long time since we've seen any similar PSU's for
laptops and similar devices, that do not have a three pole power inlet,
that includes a safety ground.  Even, if the DC output is fully isolated
from anything on the AC input side.

Take care.

€79.99 from Italy.

But it looks like it has a non EU compliant AC power lead, (looks like a
standard two blade ungrounded US lead.)  But supplied with an adapter. 
Not sure about the full legality of that practice these days.

I suspect at the PSU end of the AC lead, it uses a standard two pole
"C8" connector, so you should be able to source, or already have a
suitable lead for your own country.


Note to others in the EU.  It's the /importers/ responsibility to ensure
products sourced from outside the EU, and placed for sale within the EU,

I have no experience of this particular PSU myself.

Hi.

This sounds more like the USB<>KX3 cable driver firing up as a Serial
port that the updater was not defaulting to.That can happen if there
is something else already connected to the computer that provides a
"Serial" port for some other reason, before you plug in the KX3 cable.

I've never seen the KX3 utility run on an Apple box, but on Windows and
Linux, you get a chance to find and specify the serial port to use.

No it does not!...

OmniRig is the sole user of the COM port connected to the radio, but it
can share out it's resources to several programs at once by other means
in software, so long as the other programs are written to use OmniRig as
a radio interface.  That is good.

BUT!  Only one other program can in reality "control" the radio at any
one time *, though all of them can poll for it's status.  OmniRig will
return the last known data, without necessarily actually polling the
radio, if not needed.  That can also speed things up a lot with some
software and a rig that is otherwise slow to respond.

If your rig of choice is not listed, then read the OmniRig pages on
Alex's site, and learn how to craft your own driver file.  It's not
difficult, it just needs some thought, and time.

HamLib is a similar system, but I find tends not to work that well on
Windows.  (It does work well under Linux though.) YMMV however.

* It doesnt matter what or who's rig end user control software you use,
the rig itself is a simple single task machine.   If you start to throw
multiple commands and queries at it from different programs via a COM
port sharing tool, at best everything will be confused.  At worst,
you'll probably crash the radios own internal firmware!

That is what HamLib, OmniRig, and Flrig etc are intended to provide.  A
"managed" way to share information, and apportion control when needed.

Take care.

There is absolutely nothing wrong or bad about the 723 regulator.  But
there are a lot of badly designed units using that IC out there.  The
designers did not read (let alone fully understand) the data sheet.  And
then not helped by the physical layout people, who don't appreciate the
effect "inappropriate" wire routing can have on a regulator with a high
loop gain. Don't blame the device for poor product design.

What does go bad over time with most "Ham market" linear PSU's, is not
so much the main cap (often too high a value) diodes or pass transistors
(unless this next issue has happened.)

High value reservoir caps can overly stress the rectifier diodes, and
transformer.   Ripple is to be expected across that, and is what the
regulator is there to remove...

Anyway.  The thermal interface between the pass transistors and heat
sink often deteriorates, not helped by the usual sloppy build quality in
the first place.  (I've even seen pop-rivets used to mount regulator
pass transistors!  BAD BAD BAD!)

Same for the main bridge rectifier if that is heat-sink mounted as
well.If it is not, consider moving it to the heatsink, or fitting
one to it if there is room.

The cooler you can keep a semiconductor (within reason) the longer it
will last.   Wide variations of temperature are also bad, often for
where the leads are connected to a PCB, if not using flexible wire
resulting in failed solder joints.   Always "kink" the lead with a z
formation for mechanical stress relief, it'll last much longer as a result.

Power transistors with sockets too, can suffer intermittent lead
connections over time, due to thermal cycling and the minute repeated
relative movement between lead and socket, usually damaging the plating
on the semiconductor lead, resulting in bad connections.   Replacing the
socket will not cure that.

Dismantle, clean and re-apply fresh compound or thermal interface pad. 
Use fresh insulating (clamp) washers too if needed.   Most of all, do
not over-tighten those device mounting screws.   No, I can't quote a
torque, you'll have to research the matter, and consult the device
makers data sheet, if you can identify the devices that is...

Re solder any joints that appear a little suspicious around the high
power devices.   Replace any suspect socket connections by removing them
and soldering the wires to the device leg’s directly.  (If the device
legs plating is not badly corroded, if so, replace the device too.)

The same holds true for the pass transistor (and their drivers) emitter
ballast resistors.  Check their condition and connections.

No emitter ballast resistors?   Bad design...

For a any linear PSU, even a small fan wafting air over the heat-sink
will make a world of difference too, resulting in a much cooler PSU that
is much more reliable as a result.   If you don’t like the continuous
sound of that, fit a thermal switch to the heat-sink, say 50'C, to turn
the fan on when it gets hot...   (Or based on PSU output current...)

Re: [Elecraft] Elecraft Digest, Vol 153, Issue 41

[Dave B via Elecraft]

The "real time" (sort of) clock is powered from the batteries if the rig
is in the OFF state, and not connected to external power.  I too have
had the internal cells drain as a result.

I now keep the rig connected to the shack DC supply, even when it is not
in use, just to prevent the demise of the cell's, but also of course
keeps the clock running.

Doesn’t need much current, probably a generic 14V wall wart would run
the clock, and allow periodic battery top up if deemed necessary.

Hi.

That's a lot of open ports.  Not using a VPN then?  (Doesn’t look like
the router itself can be an endpoint though, you'd need some PC or
Raspberry Pi at the remote site for that.)

Anyway.  Find out how to backup and restore the router's configuration
to a file on a PC, and make that backup.  Then the next time you have to
change it (due to lightning strike?)  You can just load the known
working config into the new router, and likely you are ready to go.  
(Page 55 of the user manual.)

Also.  With new out the box routers, check if there is updated firmware
available from the makers.  Often the things come out of the factory
(wherever) with very old/early firmware in, that has known issues. 
Cisco are no exception to that sadly.   (Linksys in disguise!)   Make
sure you get the correct firmware, that product has two versions of
hardware it seems.

I've not checked, but "OpenWRT" or "Tomato" alternative firmware's might
run on that device.  That can often give you "a lot" more functionality,
if you need it, such as VPN endpoints!

Oh, and make sure any UPnP functionality is not exposed to the www.  
grc.com/shieldsup will test that for you...  (If you connect via the new
router.)

73 and Enjoy.

Hi.

You probably have a bad coax-to-connector problem somewhere.

If you're using PL259 type connectors, even commercially made and
moulded types, it's not uncommon.   The outer braid becomes detached at
the point where the cable enters the connector.

All too common a failing of those things, especially where cheap (braid
over foil) type coax is used.  (Cheap to the manufacturers, not to you
when you perhaps bought a ready made lead...)

Hope you find it.   A simple loop or very short dipole and diode probe
can help.  Run the system at a lowish power where it will run without
tripping, move the probe around the cables/connectors.  You'll find any
leakage that way.   A good cable will hardly indicate, a faulty one will
be "quite lively"...

73.

Does the radio still chirp when run on a large linear PSU, or from a
very well charged battery.  (In a vehicle with the engine running for
example.)

Unless specifically designed for such use, Switching PSU's are generally
quite poor in regards to dynamic regulation (such as would be needed for
QRO CW or SSB.)

However, from what Wayne describes above, even if the incoming DC dips a
little, I get the impression the DC rail for the synthesizer itself is
likely to stay clean.   But, while the SMPS is recovering from a sudden
large load being applied, it could introduce a burst of noise on the PS
lines, that might couple into other things causing trouble.

Similar things also happen when the load (RF) is suddenly turned off,
then though, you get a voltage spike, and maybe some "cycle skipping" in
the PSU as it tries to prevent such...

What make/model of PSU?   I've yet to find one for the "Amateur" market
that is anyway near half as good as the mega bucks SMPS cinder block
sized things we use in the commercial multi kW QRO amps we handle at
work.  And even they have a few issues when the amp is carrying high
levels of pulsed RF.

And the types designed for telecom or "server" use, are often very much
poorer in regards to dynamic regulation, especially if the RX current
draw is a under 10 to 15% of their rated max load, as they would have
been designed for a high power delivery, that does not vary much.

For the uninitiated, that's a number 8 size, 32 threads per inch.

American threads (non metric) are not that common outside the US, unless
one works for a US subsidiary.

"CAN Bus" (Controller Area Network) would do the job.  Either a single
(screened) twisted pair (differential signalling, highly resistant to
external EMI) or two pairs.  Its extensively use in vehicles, industry
and many places where there is lots of electrical QRM.   Serial data
rates can be high (many 10's of kBaud) and nodes are addressable.

No need to invent yet another bus.

It's not a reliable ntp "client" you need, but a reliably clean and
reachable ntp *server*.

Use the ntp pool project, not the default Windows offering for a server,
as that is so congested as to be virtually unusable.   The pool project
will find the best (closest in network terms) one for you to use.

Even using Windows own timekeeping tools and systems, when they are
pointed at pool.ntp.org for example, they will do the job more than
adequately for any of the JT modes.

No third party software needed.

https://www.tenforums.com/tutorials/6410-clock-synchronize-internet-time-server-windows-10-a.html

Will show you how.

That was found top of the list for a Google search of  "windows10
internet time settings"  There are many other hits.

Re: [Elecraft] WSJT-X Problem with K3S

To do that, you are still sending data over the USB link.  Not the same
data, but data none the less.

So, any RF ingress into the USB systems (at either end of the cable!)
Can still cause trouble.

Note, clip-on ferrite cores have very little effect at MF/HF
frequencies, unless you can wrap several turns of the USB cable through
them.  And even then, it depends on what the exact problem is where and
how the RF get's in.

I often wonder why we don't use fibre optic links for rig control and
audio.  TosLink cable and devices are available for the audio, and it's
relatively trivial to send (RS232 like) data down a fibre too.

I'll get my coat...

At least they are RF quiet!   I have several in our house.  No failures
yet in over a year either.
And we run on 240V 50Hz.

Re: [Elecraft] K3S Set-up for WSJT-X

[Dave B via Elecraft]

As Mac OS is UNIX like...   (Nothing like Windows, more like BSD!)


You may need to add your regular login username, to a group for easy
access to the serial ports.

Under many Linux(s)

sudo adduser  dialout   (Substitute your regular login user name
for the )

Will do the job.   What the equivalent command would be on a MAC I don't
know in detail.   You may even first need to make yourself root to use
that, as you need to on FreeBSD, that the MAC OS is more like than Linux.


You should also be able to find out what any USB<>Serial adapter is
known as, by using a command line tool such as dmesg, and examining the
last few lines of that, just after connecting the device to the computer.

In fact, run dmesg before, and after inserting the adapter, you'll then
see the difference...

( dmesg | tail   Should only show you the last 10 lines, not the entire
stored archive!)


Note too, that WSJT etc, uses Hamlib for radio control, that in turn
uses whatever that needs to reach the radio(s.)  So, if not already done
as part of the WSJT install, you may also need to install that separately.

Re: [Elecraft] Elecraft Website Hacked?

[Dave B via Elecraft]

You might want to use FireFox, or Chrome (Chromium) with the "Ublock
Origin" add-on installed. (I believe it will some time soon be available
for MS's Edge too, but as I've largely moved to Linux now, that doesn’t
bother me.)

You get the best of add blocking and malicious script prevention, while
allowing intentionally visited web pages to function as they wanted you
to see.   In essence, the best of AddBlock+ and NoScript, but without
the hassle.

In the case a site "Needs" you to see adds (some "commercial media"
sites etc) then you can allow such things on a case by case basis,
without compromising yourself on other sites.

If using FireFox, erase your browsing history and set it to not save
any, & have it erase all cookies when it shuts down, never save
passwords, and not use the master password facility (there are issues
with that, should your master pw get "lost"...)   Similar settings are
available within Chrome(Chromium) of course.

Then, each new browsing session, is just that, new...

If you still experience unwanted redirects, check your systems "hosts"
file for anything odd, also see if the same thing happens with a totally
unrelated system on the same net connection. (Tablet or phone on WiFi.) 
If so, your ISP could be sending you places you don't want to go...

No affiliation with any of the above mentioned "products", just a happy
user of some...

Happy New Year.

As Tim KG1GEM says...

You'd need to build the KX3 utility from source to run on the Pi.   The
reason?   The Pi uses an ARM CPU, not an x86 architecture device, that
the pre-compiled KX3 utility is built for.

Perhaps the util' author could cross compile it, or perhaps someone
donate a Pi to him, so he can build a version on it or somehow persuade
him/Elecraft to make the sources available to the community.   I think
the latter will not happen sadly, as I suspect there is some "secret
sauce" in there regarding firmware transfer methods and protocols etc.

The other way would be for it to be rebuilt as a "Java" application,
then it'd run on just about any platform that supports the Java Runtime
Engine (JRE.)   That is not a trivial undertaking, especially as it
needs to use serial, (aka COM) ports to tallk to external hardware.  

(Note:  Java is *not* the same as Javascript, that browsers use.  Plus,
it is possible indeed desirable to disable any/all browsers ability to
launch a "Java" app.)

I believe there is a usable JRE for the Pi, but not tried it myself.
