Re: [Elecraft] KX3 RF out voltage measurements...

2016-06-07 Thread Bill Frantz
It is best to use CW or Tune or even AM to check power output. 
If you don't speak into the mic in SSB mode, the output should 
be zero, as the carrier is suppressed and with no audio, there 
is no side band.

The reason I ask this is because if I just key the mic with silence and
the radio set for 10W with a input power supply of 13.5V DC I measure
4.7mv DC at the TP1 on the DL1 unit.

If I speak into the mic I see voltages from 11 - 18V DC from the TP1 on
the DL1 unit. It seems to me that I need to be speaking into the mic. I
figure if I was checking the RF out in CW mode I would need to key the
keyer in some fashion.

I know this seems like an elementary level question but I would really
like to verify the RF power out.

Any information is greatly appreciated in advance.

Re: [Elecraft] Shipping of KX2's

2016-06-07 Thread Milt -- N5IA
And with the K3 in 2007 the order placed in May was ready to be shipped the 
following January 2008.  But the 2nd RX wasn't installed and was still not 
available, so I took delivery of the complete ordered radio nearly one year 
after ordering.


In the mean time I had the privilege of getting acquainted with the K3 at 
VP6DX.


As stated; the wait was worth it.

[Elecraft] KX2 batteries on airlines

2016-06-07 Thread Bruce Nourish
Just checking up on the rules...

https://www.faa.gov/about/office_org/headquarters_offices/ash/ash_programs/hazmat/passenger_info/media/Airline_passengers_and_batteries.pdf

The KX2 battery is a ~28 Wh lithium ion. Reading the chart, that means:

* Installed in the KX2, it's legit for carry-on and checked.
* Spares (not installed in the KX2) may be carried on in any quantity,
provided they are for personal use (not resale), and are protected from
short circuit and damage (e.g. tape on the terminals, carried in a
protective pouch).
* Spares may NOT be checked into luggage.

Note that plugging the battery into a charger doesn't make it "installed";
it has to be in the KX2, or it's a spare.

Re: [Elecraft] Field Day

2016-06-07 Thread Bill Frantz
I have been using a solar charge controller from CIrKits 
. The kit comes in a 20A version 
and there are modification instructions for 40A, 60A, and 80A. I 
have the 20A version and have noticed no RFI in my suburban QTH. 
The higher current modifications change some of the circuit 
resistors to keep the RFI low, so low RFI was one of the design goals.


This controller feeds full panel current to the battery until 
the voltage reaches the float voltage and then floats the 
battery at that voltage. This techniqueis a good for lead-acid 
batteries but is probably not appropriate for lithium family chemistries.


It is also not the most efficient way to charge a lead-acid 
battery. Higher efficiency can be achieved by charging at a 
slightly higher voltage and only reducing the voltage to the 
float voltage when the charge current becomes low. With my 7.5A 
rated panels, I can recover the batteries charge in a day after 
spending a weekend contesting at 100W, so the additional 
efficiency is not a major concern. The charge system also works 
well on field day at QRP power levels.

Re: [Elecraft] [KX3] Puter logging help

2016-06-07 Thread Mike Dodd

On 6/7/2016 1:59 PM, Bob N3MNT wrote:

The program  is N3FJP.


I use Scott's Amateur Contact Log (ACL) 
 for general logging, and like it a 
lot. It talked to my KX3 and it talks to my K3s.


I bought Scott's entire suite of software licenses, and used a couple of 
contest programs, but did not like having to download and install a 
separate  program for each contest each year. Now I use N1MM+ for all 
contests.


I like the screen layout of ACL better than other logging programs I 
tried briefly. The current-QSO portion of the screen can be customized 
in field colors, font size, and even field placement. The log portion 
can be customized as well; I like to see many fields, so I run into 
screen width problems. Maybe I need a 27" monitor. :-)


ACL has some annoying (for me) quirks that I've asked Scott to fix, but 
he's been busy rewriting most of his software for the latest DotNet 
platform, and the quirks remain.


One annoyance is, when editing a log entry (not the current QSO), a 
separate dialog opens, and pressing ESC to cancel does not work -- you 
have to click the CANCEL button on the dialog. I'd rather just hit a key.


ACL has a "net" feature, where, as NCS, you can quickly log stations 
checked into a net. After they're entered in the "net" dialog, one 
button cvlick saves them all to the main log.


One nice feature is that you can create a comment such as "XYZ Net" that 
is automatically added to each station's entry.


But this comment is appended in the comment field to the station owner's 
name and address from a callbook lookup. Appending the comment shoves it 
way off to the right where is isn't visible in the general log.


Worse, if you decide to manually delete the auto-filled name and 
address, you can't do it by selecting all the text, and hitting DELETE. 
Only the _visible_ text is selected and deleted; you have to do this 
three or four times to clear the field.


There are a few other annoyances, but all-in-all, I'm pleased with ACL.

Re: [Elecraft] Difference in DSP in K2 and K3S

2016-06-07 Thread Don Wilhelm

Paul,

Comparing the technical side of the K2 DSP NR with the K3 NR is like 
comparing apples and oranges.

The KDSP2 is DSP added at audio, while the K3 NR is done at the 15kHz IF.
The K3 offers many more settings that are available with the K2 DSP, so 
I encourage you to experiment some more.


The way the NR algorithm works is that the DSP searches for what it 
believes to be a correlated signal and builds a filter around that 
signal.  That may result in the 'robotic' voices that you mention.


Not all noises are the same, and you may have to find the settings that 
deal most effectively with your particular noise - as I indicated, 
experimentation may be necessary.  You should look at the manual page 
dealing with "Reducing Interference and Noise" for some clues and 
cautions about NR.  Check to see if Noise Blanking might be more 
effective than NR for the type of noise you are dealing with.  A 
combination of the two can also be used if that should help.


73,
Don W3FPR

On 6/7/2016 5:16 PM, Paul Wilton wrote:

I have been using a K3S in a 2m SSB VHF contest this evening and find that the 
DSP NR is a bit a disappointment compared with my usual K2 rig.  My QTH has a 
fair degree on man-made noise so on the K2, I normally run with the NR at level 
4 (factory settings - I haven’t adjusted them).  However, when using the NR on 
the K3S this evening, when I adjusted it to get a similar amount of noise 
reduction, I find that is accompanied by a lot of swooshing noise modulated 
with an interval of between 0.5 to 3seconds.  Also, the voices seem a lot more 
robotic and harder to understand.

I did try all of the NR settings but didn’t really find one which matched the 
niceness of the K2.  Has anyone else progressed from a K2 to a K3 on VHF and 
would like to comment on the effectiveness of the NR?  And more importantly, 
are there some settings I can try to get the K3S to sound like my K2?

Re: [Elecraft] Question re TXMON

2016-06-07 Thread Alan Bloom
The waveform display in the P3 TX monitor auto-ranges to keep the 
modulation peaks within the display limits.  However, if the forward 
power gets high enough to over-range the ADC, then the waveform will be 
clipped.  With the 200W HF sensor, I believe the clipping level is about 
240-250 watts, depending on the calibration.


With 100W out of the K3 and assuming 100% efficiency in the tuner, the 
SWR would have to get up to about 7.7:1 to cause clipping of the 
displayed waveform.

[Elecraft] Difference in DSP in K2 and K3S

2016-06-07 Thread Paul Wilton
I have been using a K3S in a 2m SSB VHF contest this evening and find that the 
DSP NR is a bit a disappointment compared with my usual K2 rig.  My QTH has a 
fair degree on man-made noise so on the K2, I normally run with the NR at level 
4 (factory settings - I haven’t adjusted them).  However, when using the NR on 
the K3S this evening, when I adjusted it to get a similar amount of noise 
reduction, I find that is accompanied by a lot of swooshing noise modulated 
with an interval of between 0.5 to 3seconds.  Also, the voices seem a lot more 
robotic and harder to understand.

I did try all of the NR settings but didn’t really find one which matched the 
niceness of the K2.  Has anyone else progressed from a K2 to a K3 on VHF and 
would like to comment on the effectiveness of the NR?  And more importantly, 
are there some settings I can try to get the K3S to sound like my K2?

[Elecraft] KX2 /KX3 Headset Question

2016-06-07 Thread Jim Finan
As a former air Traffic Controller I used the Plantronics StarSet headset for 
years. I've been wanting to adapt one to my KX3 (and now my KX2). 

Jim (‎K9YC), in his RFI treatise, indicates that Plantronics headsets are a 
good choice. However, his recommendations were regarding the $25 variety, not 
necessarily the StarSet. 

My questions are:

1. Has anyone adapted a StarSet for this use?
2. Are there any reasons why the StarSet would be a bad choice?
3. Can the matching hand switch be adapted too?

Any suggestions would be appreciated

While the StarSet is only a single-sided headset, I haven't seen many that are 
lighter or  more compact. It would seem to be ideal for portable SSB. 

I originally wanted to do this when I got my KX3 a couple years ago but my 
interest was rekindled after receiving my KX2 a week or so ago. 

Thanks and 73,

Jim

As far as I know, the only headset/mics that need an adapter would be 
those that have a single Tip-Ring-Ring-Sleeve (TRRS) plug. The Star-Tech 
MUYHSFMM adapter looks like the right part. A search for that part on 
amazon will find it.


In the KX2 and KX3, the mic jack is TRRS, but the two rings are used for 
logic switching with an Elecraft mic (PTT, up/down). With any other mic 
(including one using this adapter), we need to go into the Menu and set 
MIC BTN to "Off" and set the radio to use VOX (or use the XMIT button).

Agreed.

I disagree with this. The correct advice is to 
avoid microphone TYPES that are subject to 
breath pops, and to use the mic you have so that 
your voice doesn't generate pops. So -- 1) avoid 
directional mics and noise-cancelling mics, both 
of which are subject to breath pops; 2) position 
the mic a few inches above and to the side of 
your mouth. The boom mic of a headset makes this 
VERY easy.  The Yamaha CM500 and Koss SB35 are 
good choices. See the photo on page 5 of 
http://k9yc.com/ContestAudio.pdf  for an example.



  You need to
decide between hand-held, desk or boom mount 
and a mic attached to a
headset. And you'll want a connector wired for 
the K3.


I find a boom mic headset ideal for operating 
SSB. The CM500 and SB45 plug straight into the 
rear panel of the K3 and K3S. They are very 
comfortable, and both mic and headphones sound 
great.


Elecraft makes a nice set of mics that take all 
the hassle out of having the
right connector and of course the company 
stands behind them. (In "full
disclosure", I'm not an employee, but have been 
associated with Elecraft for
16 years so far. That has given me the 
opportunity to use several of their

mics.)
I love the guys at Elecraft, but I don't 
recommend the mics they sell, which they buy 
from third party vendors, and must sell at a 
significant markup. Elecraft is in the RADIO 
biz, and they're really good at it. Those Yamaha 
and Koss boom mic headsets offer FAR more value 
for the money. If you want something more 
compact to carry up the trail with your KX2 or

which plug into those radios directly, or with a

Re: [Elecraft] Proposed New KAT500 Option

2016-06-07 Thread Michael Walker
All

I have been running a remote base for over 10 years now, all via a variety
of internet tools.

If we are redesigning logic, I think we really need to consider moving up
the ladder and not making older technology do the heavy lifting.

Rather than using RF to manage the switching, or even RS232, we should try
to use this new technology called TCP/IP.  LOL

All joking aside, we really need to move to all IP addressing for antenna
switches, rotators, amplifiers and more.  Flex is already doing that in so
many ways, that I have now gone the Flex route for my remote base.  It has
reduced my wiring head aches 10 fold and increased my over all reliability
at least that much

Anything RS232 bases is now converted to RS232 over IP and where possible,
using Raw sockets.  PSTRotatorAz is the software tool that really helps
glue this together.  BTW, the devices I am using for RS232 over IP cost
about $20 each and work well.

I now run a LAN cable to the base of the tower for the Steppir Controller,
Antenna Switch and Rotator.  I cable run.  I could also move the Radio
there if I wished and gained several DB just by cutting out problematic RF
cables that age over time.

Once you start down this path, the ability to scale gets easier.

Re: [Elecraft] Proposed New KAT500 Option

2016-06-07 Thread Larry Gauthier (K8UT)

Ed,

Your proposed solution sounds similar to my current configuration, except 
that remote antenna switch selection is derived from a connection on the 
K3S - not the KAT500.


I have two main coax cables leaving the shack - one goes to a remote switch 
at the top of the tower for selecting bands 6m - 20m; the other to a second 
remote switch for selecting among dipoles and loops for 30m - 160m. The 
KAT500 automatically determines which coax to use (Ant1 for 6m - 20m coax or 
Ant2 for 30m - 160m coax), while a band decoder attached to the K3S selects 
which specific antenna on those remote switches gets activated.


This arrangement exploits the standard features of the KAT500 and the K3S 
without any additional hardware or programs. You might be able to accomplish 
the same thing using the band select outputs from the rig.

Subject: [Elecraft] Proposed New KAT500 Option

Hello,
As part of my work designing and maintaining a remote station, I can
think of several ways to use a tower-mounted RF-actuated programmable coax
switch. So I'm wondering how hard it would be to add an optional external
coax switch for use with the KAT500? This would offer a couple benefits -
ability to tower-mount a coax switch (but maintain control of that switch
via the KAT500 circuitry and utility program), and it would increase the
number of available antenna ports from the current three to perhaps 6.
If this option were available, it could be implemented using a small
RF-sensing control box which would allow the KAT500 to remain as-is. The
KAT500 PC Data line would then run through the external control box to the
user's computer so that the utility program, once updated, would be able to
show coax switch status and allow the utility to program how the
tower-mounted switch responds. The user could hook the external RF-sensing
control box to ANT1 on the KAT500 (so ANT1 would be the position to select
if/when one wanted to use the tower-mounted switch). A switch control line,
and the RF coax would be the two lines running to the tower-mounted switch.
I'm posting here because it seems like the circuitry to sense frequency
and actuate the switching is already designed, and could be mostly
duplicated in the external RF-sensing control box. Would anyone else be
interested in such a "smart RF coax switch" option?  I suspect the numbers
may not support this as a new product, but I am curious, as what I would
like to see is frequently out of phase with what others need ;)

Re: [Elecraft] KX3 Utility

2016-06-07 Thread Dave B via Elecraft

All I did in the past, was to:-

Create a new folder for it from my home folder.

Extract the contents of the downloaded archive to that folder.

Create a desktop launcher pointing to the executable.

Install curl (and it's dependancies.)  Needed to download firmware from 
Elecraft's site.


$ sudo apt-get install curl


I was already a member of the "dialout" group, but you might need to 
join that group


$ sudo adduser  dialout   (Of course, sudo will ask for 
your password.)



Then log out, and log back in again.

After all that, it "just worked."   Even with any of my generic 
USB<>Serial leads and homebrew cable, or the Elecraft USB<>KX3 lead.



The above worked well on Lubuntu, and Mint.   Both derivatives of Ubuntu.

[Elecraft] KX3 ATU Problems

2016-06-07 Thread Enzo Adrian-Reyes
Hi there

At the moment I've had so many issues with my KX3 I am kind of wondering
what is wrong with it.
The problem is I dont use it much but so far its died on me three times,
any how the new issue so far is, the ATU, it wont tune down my end fed
antenna below 24.5-1 SWR,

No matter the band the lenght of the end fed, with a balun with no balun it
doesnt work at 50Mhz it tunes down 8.9-1swr.

This has been happening since last year, the first time i was on a
buddipole while on a DX-pedition, and generally thought it was a one off
thing, but now this second time its done it again, I just cannot get the
unit to tune it down.

The antenna is a EARCHI 40-6m end fed antenna, I've sold the buddipole
because I couldnt go for a while, but this is now persistant.

Any ideas on what is going on?

Regards
VK3FRAD

[Elecraft] [OT] Re: New products

2016-06-07 Thread Dave B via Elecraft



Just a benign note.  Primary aircraft engine controls will probably always be manual and 
"hard".

~~~

Sadly, just about all modern commercial passenger aircraft now are all 
fly-by-(electrical)-wire, the pilot tells the array of multiple flight 
computers what he wants the plane to do, they take a majority vote on it, then 
make it happen, even the engines are not under his direct influence...

I'm not even sure if there is any mk1 hydro/mechanical linkage between the 
rudder pedals and the nose wheel any more...

It's only a matter of time before such technology (if not already done) 
migrates to light aircraft.

Yes, it's all a little scary.

At times I envy most of the sheep who don't know much about any of this, and assume 
the man in the left seat with a view & wearing the big hat is fully in control 
all the time.

[Elecraft] Shack Bonding

2016-06-07 Thread Joel Black
Ok, if I understand Jim’s shack equipment bonding slide, I need to bond 
anything that has an unbalanced connection (excuse me for my poor ASCII drawing 
- you’ll have to use a fixed-width font to view):

Equipment:

iMac - bonded to USB interface and KX3
KX3 - bonded to iMac, USB interface, P/S, and PX3
PX3 - bonded to KX3 and P/S
USB interface - bonded to iMac and KX3

  P/S
//   \\
iMac  KX3 === PX3
   \\//|
  USB  |
   |
ANT SW

I’m trying to emulate Jim’s drawing with the double lines. Since the coax would 
be bonded (I typed “grounded” and changed to bonded ;) ) to the case on the KX3 
and the antenna switch, I don’t *need* another bond?

Since there’s no feasible way to bond the iMac to anything, make sure 
everything with a green-wire ground is on the same green-wire ground circuit 
and use Type 31 ferrites on the leads to power, KX3, and USB interface?

As for the USB interface, the circuit board is “bonded” to the aluminum chassis 
via a compressed spring. I can take a picture if necessary. My thought is to 
take a brass bolt, a pair of star washers, and a brass thumb nut and create a 
bond point on the aluminum chassis.

Now, if I add anything in the chain, say an audio amp/splitter to send the SPKR 
out to speakers and headphones or something else, I would need to bond that 
also to whatever it has an unbalanced connection, correct?

Please be critical, I’m trying to learn and understand. Kid gloves don’t work 
on me but 2x4s upside my head do. I’m Scots-Irish/Danish and have a *very* hard 
head. ;)

comfortable, and both mic and headphones sound great.



Elecraft makes a nice set of mics that take all the hassle out of having the
right connector and of course the company stands behind them. (In "full
disclosure", I'm not an employee, but have been associated with Elecraft for
16 years so far. That has given me the opportunity to use several of their
mics.)
I love the guys at Elecraft, but I don't recommend the mics they sell, 
which they buy from third party vendors, and must sell at a significant 
markup. Elecraft is in the RADIO biz, and they're really good at it. 
Those Yamaha and Koss boom mic headsets offer FAR more value for the 
money. If you want something more compact to carry up the trail with 
your KX2 or KX3, look at lightweight computer headsets, which plug into 
those radios directly, or with a simple adapter you can buy on amazon 
for $5.

[Elecraft] Inserting TMP cables - was: Problems with K144XV Transverter for K3S - Can't Hear Anything

2016-06-07 Thread Johnny Siu via Elecraft
In the installation of TMP of K144XV, I opened up the top cover of K144XV to do 
the installation so that I could ensure what I did was fine.  After that, I 
closed the top cover.

 主題︰ [Elecraft] Inserting TMP cables - was: Problems with K144XV Transverter 
for K3S - Can't Hear Anything
   
I agree that TMP cables can be difficult to insert, but here is how I 
proceed:
First make sure there are no strands hanging out of the center conductor.
Then look at the very tip of the center conductor.  If it appears that 
the crimping process has produced two "ears" that extend outside the 
diameter of the center pin, you can use long nose pliers to reduce the 
width of those ears just a bit.  In other words, you are 'rounding" the 
tip slightly - do not take this to extremes and crush the tip, a gently 
'rounding' is all that it takes.

Then insert the male TMP into the female - look at the shell - if there 
is a gap between the male and female shells, the center conductor of the 
male tip is not yet started into the center conductor of the female 
jack.  Do not push yet, but twist and 'wiggle' the connector until the 
center conductor is started on its proper path.
Once the shell of the female closes the gap to the male connector shell, 
the center conductor has found its home.  Then is the time to push it 
home - a bit of a twist will help.

If you push hard on the connector before the center conductor has 'found 
its home', you will end up pushing the jack off its mounting lugs.  
Pressure toward the jack will not help until the center pin has begun 
seating.
