I listen to the AM Broadcast band using the SSB detector. Max RX 
bandwidth is 5 kHz, which just about optimum for speech. I use it to 
evaluate performance of RX antennas, mostly to make sure they're working 
after storms. Stuff tends to fall on them, like branches and even entire 
trees.


I've never cared about AM TX.

The only things that Elecraft should do to prevent lightning damage are 
to properly terminate cable shields to the shielding enclosure at the 
point of entry, properly terminate power system safety ground contacts, 
the the shielding enclosure, and otherwise practice proper bonding 
within their products.


The rest of it is up to us. About a week ago, I posted a link to 
tutorial slides for talks that I've done on the topic. EVERYTHING shown 
is good engineering practice to prevent lightning damage, and much of it 
also minimizes issues with RFI. Anything that we fail to do is an open 
door for lightning damage.

Re: [Elecraft] K4 Remote: My QTH vs. a friend's, many miles to the north

[Dave (NK7Z)]

Hi again,

Your grounding sounds good.  I suspect the USB connection used by 
Elecraft was standard, and not something that was lightening proof, so 
yes, any manufacturer can do more, the question is why increase the cost 
of the amp to everyone, when there is little chance the protection will 
ever be used?


If there were a preponderance of KPA1500 amps loosing USB drivers, then 
I might agree with you, but so far, your amp is the only one I have 
heard about that took a lightening hit, and the only one I have heard 
about that has lost a USB driver...


If all you lost was the USB driver, then you are a lucky man, go buy a 
lotto ticket today!!  I would expect a lot more to be damaged by a 
lightening strike...


In any case, it is too bad the amp failed, but by that same token, it is 
really good that is all that happened!


As you mentioned a bit ago, the more hi-tech an items is the more 
sensitive it becomes...

Jorge,

I can only go by what you said:

"Last week I experienced a lightning strike"

That sounds a lot like a direct discharge into the shack, so I am
responding to your comment, if that is not correct, please help me
understand what actually happened...

Lightening is strange, it can take out one piece of equipment, and not
touch another...  It all depends on how your shack is grounded, and how
it is bonded.  When grounding commercial equipment, even the path the
wire takes is important...  Curves, straight line runs, etc...

What sort of ground system are you using, and what sort of lightening
protection did you have in place at the time of the lightening event?

Take a look at:

https://www.nk7z.net/building-a-coax-entry-panel/


That is my entry panel.  I am slowly building a ground ring around the
house...  Why?  Because only I can build a system to help reduce the
chances of lightening taking out something in my environment.  It is
after all my home, and my environment, so I can not, and do not, hold
Elecraft responsible for things they can not control.  Elecraft, can
not
be responsible for my grounding, and bonding practices.

Respectfully, in your original question you implied that Elecraft
should
have done more to make the KPA1500 withstand an as yet, correctly
defined lightening event.  Again, respectfully, if you believe Elecraft
failed in some way, then you should say what, and how they failed...
Not imply they should have done more...  That is unfair.

With respect to the weekend-- I hope to see you in the 7QP contest!  I

care

Hi Dave

For Elecraft to protect the amp against a lightening strike as you

Re: [Elecraft] K4 Remote: My QTH vs. a friend's, many miles to the north

[Fred Jensen]

Supported myself during college at the local TV station ... very late 
1950's. Station was on a ridge, we got lots of lightning strikes on our 
tower. The grounding ["earthing"] of the entire station was super 
extensive. We still occasionally lost equipment, mostly the smaller 
uwave equipment outside, despite the grounding.  Direct lightning 
strikes are so intense and large.  Lightning is also an RF event.  What 
happens in a near but safe place can create very large currents in 
nearby conductors.

hi Dave

I don't know what to tell you, I imagine that a direct discharge into the
shack would have burned everything.

I had 6 USB cables connected to the laptop, they burned the USB of a box of
GHE that costs $160 and the USB of the KPA1500 that costs +$7000

rotor controls and other PCs did not burn

In short, it was the fear I had of buying new and sophisticated equipment
living so far from where the company is located.

Re: [Elecraft] K4 Remote: My QTH vs. a friend's, many miles to the north

[Dave (NK7Z)]

Hi Jorge,

That device would not stand a strike...  As per the US Weather service, 
(https://www.weather.gov/safety/lightning-power), a typical lightening 
bolt runs around 300,000,000 volts, at 30,000 amps.  That device is 
speced for 4000 volts...


For Elecraft to protect the amp against a lightening strike as you 
described you had, they would need to add a LOT more hardware than that 
to the price of an already expensive amp, and most people would never 
see need the protection.  Hence why they don't even try and protect 
against a direct lightening strike.


The onus for lightening protection always rests with the device owner.

I can’t see where a more robust USB connector would affect remote operation via 
a LAN cable.

Better isolation can be obtained by installing a WiFi dongle.

Re: [Elecraft] K4 Remote: Station design

[Rick NK7I]

 * Elecraft has no control in how one sets up (or uses) a station.
 * A remote station needs all of the same protection enjoyed by any
   other station; they are the same except one is used remotely.

On the last premise; set up the remote station as if it were any other 
station; RFI and noise mitigation, generator back up power, UPS, 
lightning protection*; GROUNDING AND BONDING, heating and (!) cooling 
(!); again just like any station should appear and operate (even if it's 
stuffed into a closet).


The power supply system should provide for continuous power to the 
network too.  It's MORE important if the station is intended for remote 
ops.  The control operator (local or remote) is required to have FULL 
control over the station operations; plan for worst case events that 
would affect that; loss of network is a key consideration for remote use.


[I have a lot of UPS, one per mesh node included, for the approx one 
minute until the generator switches in upon power failure and one  UPS 
per computer power source to keep the services I provide, online.  
Simply because Starlink and the network takes over ten minutes to 
re-establish with a power loss.  That's a long key down time!]


It is up to the USER (remote in particular) to operate the station 
(remote or local) in a way that does not cause harm (on the air or 
through ab/use).  This means small things like making sure the 
transmitter is not locked on (CW key down, FSK transmit) in the event of 
a network fail so it cannot be unkeyed (use of VOX or macros and memory 
use for sending non-phone message strings)


That's nothing new.  A remote station, is just another station with the 
same needs and planning as any other station; except the goal is to use 
it remotely and the ability to control it at all times during use.


73,
Rick nk7i

* Lightning protection how-to or discussion is beyond the scope of this 
group, but EVERY STATION should have a system in place WITH grounding 
and bonding of every item in the shack, includes every wire that enters 
the building (cable TV, phone, power, DSL) or that sticks into the air 
for radio (tower/mast, sat dishes, antennas).


Even if the station location rarely has lightning.  Properly done, the 
protection system would also help static buildup, from rain, wind, snow, 
dust or any other cause.  Static discharge cause is more than lightning 
and can also damage (or destroy) equipment.


Even then, a direct hit may not save the station but it will show what 
was NOT properly taken care of, what was missed in the protection system.


In some cases, it can even lower the noise floor (MAY, not will).

Re: [Elecraft] K4 Remote Lives and Breathes!

[Gregory Mitchell]

This is why Elecraft needs to get serious about having IPv6 support in the K4. 
Because of stateless auto config, a minimal support would just be to enable 
stateless auto config on the network interface and provide the ipv6 address on 
the menu as readonly.

Re: [Elecraft] K4 Remote Lives and Breathes!

[John Canfield]

I was behind a *double* NAT until I got a static IP but in the meantime 
I setup a reverse SSH tunnel It's been several years since that but it's 
a real pain to setup and keep connected. Finding a host provider that 
would permit a reverse tunnel is a challenge, few will do this.

This issue is real. A problem is also there is quite many port forward
configurations to setup as one setup a station.

There is methods to punch through NATs, and I hope one have chosen to
use an approach that does this. One is to operate over a VPN that have
these abilities. Another is to use a standard tunnel usinging say TLS
that also include the punch-through capabilities.

Also, IPv6 is starting to replace the IPv4 NAT/CG-NAT hell. It's been a
long coming for sure, but there is plenty of signs it is happening.
While initial release may be IPv4 limited, IPv6 should be high up on the
list of thigns to fix if it is not already handled. This should not be
relevant only for the K4, but any device.

When wearing another set of hats, I work on these issues.

Re: [Elecraft] K4 Remote Lives and Breathes!

[Rick NK7I]

As (other) Rick says, port forwarding varies between routers; but the 
two key points to research for your router are:


1)  Assign (reserve) the K4 MAC(s) to specific IP addresses, so the 
K4(s) is/are ALWAYS at the same LAN IP address (reboot the K4).
2)  Port forward 9204 to the K4 (only one can be shared with the 
outside, if more than one K4 on the LAN) IP address.


You may want to make sure that a password is made within the K4 (instead 
of anyone) so you have some access control.


If you have (like me) Starlink or other CGNAT using ISP, then it gets 
more complicated and probably isn't a topic to be discussed on this list.


Across my Starlink LAN (I have two LAN), it's working beautifully and 
should be available 'real soon now' for public beta... have some 
patience yet while the field test team runs it through it's paces and 
some spit and polish are applied.

I faced such a dilemma some years back when it looked as though we would
need to rely on a cellular router for an ISP.  Fortunately, that didn't
become a permanent solution.

My solution was setting up an AWS instance to which I set up a reverse
SSH tunnel from home and then I could SSH to it from elsewhere and
connect to the reverse tunnel.  Conceptually it's somewhat like a VPN
only it had some manual steps in place.  I now have a similar setup from
a Raspberry Pi running AllStar at a repeater site that connects to a
local system and sets up an SSH reverse tunnel end point.  I did try to
set up a Wire Guard VPN a few years back but had no luck  Perhaps I need
to revisit that idea since things have had a few years to mature,
including me!

Re: [Elecraft] K4 Remote Lives and Breathes!

[Magnus Danielson via Elecraft]

This issue is real. A problem is also there is quite many port forward 
configurations to setup as one setup a station.


There is methods to punch through NATs, and I hope one have chosen to 
use an approach that does this. One is to operate over a VPN that have 
these abilities. Another is to use a standard tunnel usinging say TLS 
that also include the punch-through capabilities.


Also, IPv6 is starting to replace the IPv4 NAT/CG-NAT hell. It's been a 
long coming for sure, but there is plenty of signs it is happening. 
While initial release may be IPv4 limited, IPv6 should be high up on the 
list of thigns to fix if it is not already handled. This should not be 
relevant only for the K4, but any device.


When wearing another set of hats, I work on these issues.

We have a local remote station here in Indy that has a K4 and several of the

I thought that what people really wanted was the promised app that would let

Buying two K4s seems like a very financially inefficient way to go. 
Bidirectionality doesn't sound like a practical plus.

and Elecraft programmers are hard at work on them.

Some highlights:

 - Cabling changes required: *ZERO* - leave both stations in their local
 configuration. You do need a way to turn on a remote K4. I'm using N6TV
 "K-ON" dongles and remote power switches. I think you can also do it from a
 connected KPA1500 and KPA1500 Remote. No need to leave anything powered on
 when not in use.
 - It's *dead simple* to connect - just specify an IP address on the
 client (control) K4 and set up one port forward on the LAN router at the
 server (remote radio) site. Passwords will prevent unwanted intrusion.
 (Compare to over 100 parameters that have to be set up between pairs of
 RRCs - and they only work one-way!)
 - Connection takes about a second.
 - It's bi-directional - any K4 anywhere can control any other K4
 anywhere. No hardware asymmetry.
 - CW sidetone and Voice monitor are local, so unaffected by latency.
 - Use the keyer inside the client K4 or an external keyer.
 - Plays nicely with loggers like N1MM. They see the local K4 and don't
 realize it's controlling a remote radio.
 - You can update the firmware in both radios from the K4 at either site.
 - ... and more

I've been an avid remote op for a decade now and this is better than I
expected, like K4 itself well worth the wait. Hang in there, folks,
it's really coming. Really.

Re: [Elecraft] K4 Remote Lives and Breathes!

[Mark Musick]

Dave,
That is not what that configuration is about.
What this is for is for those remote stations that have a K4 and have many 
remote operators.
We have a local remote station here in Indy that has a K4 and several of the 
Remote operators have K4s. Now they can operate remotely from home as if they 
were at the remote site.

I thought that what people really wanted was the promised app that would let 
users remotely control the K4 from their desktop or other device.

Buying two K4s seems like a very financially inefficient way to go. 
Bidirectionality doesn't sound like a practical plus.

 As a retired software QC engineer (UNIX OS and layered products), I'm 
curiousas to what kind of testing would be needed at a mountain QTH versus a 
valley QTH. :-)
In all seriousness, congratulations - I can easily imagine that it's been a LOT

Re: [Elecraft] K4 missing features

[G4GNX]

Maybe it depends on the individual setup.

Despite using a steerable double mag-loop for RX, the urban noise is 
horrendous. I don’t find the K3S NR to be particularly good and I’ve placed a 
BHI Parametric Equaliser NR box in line. For me, it doesn’t do a great deal - 
except for one day last week, where the signal I wanted was strong (S9) and 
about equal to the ambient noise. I then found that I could null out the noise 
entirely with the BHI unit, giving me near armchair copy. When the wanted 
signal is below S9, noise reduction results in degradation of the wanted audio 
to a point where the NR is non-effective.

Currently, I find the K4D noise reduction works quite well, albeit using a 
different RX antenna.

As Wayne has already stated Q1 2024 and we’re not there yet, why would you 
expect a different answer at this point?

Re: [Elecraft] K4 discussion on groups.io

[Mark Musick]

Hi Dave,
I can think of three reasons why in-depth discussion of the K4 is not taking 
place here on this reflector.
The biggest reason is this reflector does not support HTML or attachments. With 
the K4 being able to attach screenshots of the K4 display is very important in 
trouble shooting and answering questions about settings.
The second reason is the file support on the K4 reflector. Where files can be 
deposited for subscribers to access at will. This reflector does not support 
that kind of depository. This reflector does have an archive like the K4 
reflector, but in my opinion the search capability on the K4 reflector is 
superior.
The third reason is , while this reflector has served us well when Elecraft had 
only a few products, now it has become a real navigation issue with so many 
products. Yes, you can set rules to get only those K4, K3, etc. to go to a 
certain folder, but that requires the sender to put the appropriate subject 
line in. This doesn't always happen. The K4 reflector example is people will 
change the discussion of a thread and not update the subject line. On the K4 
reflector or the KX reflector you know the discussion is only about the K4 or 
KX radios.
Fourth on the group.io reflectors there is a dedicated administrator. Back in 
the day it was easy for Wayne and Eric to administer this reflector now with so 
much activity it is hard for them to do that. They have now passed that on to 
Keith. Keith's job is to fix K3s and K4s. I would prefer as a customer that he 
continue doing that and not worry about administering this reflector.
As to being a nonmember of groups.io, it is a simple task to join groups.io and 
subscribe to any groups/reflectors you wish. I belong to eight groups, all 
related to amateur radio.
Also, I have mentioned before you don't have to own or even aspire to own a K4 
to join the K4 reflector. There are subscribers there that their main interest 
is SDRs in general etc.
And one more reason. There are subscribers on the K4 reflector that only own a 
K4 and no other Elecraft equipment and they don't want to filter through all 
the other discussions about Elecraft equipment they don't own or care about. 
They are not going to subscribe to this reflector.
I hope that explains things for you Dave. Sign up on the K4 reflector and learn 
more about it. You are more than welcome there.

Mark, WB9CIF

While separate groups for K1, K2, K3, K4, KX2, etc are up to whoever sets them 
up, lets not forget the main product for Elecraft at the moment is the K4, so 
why not discuss it on this open group that is run by Elecraft?

The K4 groups.io archive is closed to non members, which isn't helpful to 
anyone who doesn't wish to join but merely wants more information on a product.

I guess this group doesn't allow attachments, so the screen shot didn't 
come through. Just go to your group list, and the link will be obvious.

I think your description is great! It covers the information thoroughly 
and provides all the info needed to subscribe to a group.


One thing I would add is, once you're subscribed to one or more groups, 
those appear on the Your Groups list. Next to each group name is a link 
to open a page where you can set your email preferences; see the

Hi Magnus,
I take it you are not familiar with groups.io so first groups.io is a web-based 
collective of lots of different reflectors. Someone else can probably give a 
better description.
Open your browser and type in groups.io and it will take you to their sign in 
page. Once you are a member of groups.io you can subscribe to any of the 
reflectors using groups.io.
I'm currently subscribed to eight different reflectors that use groups.io.
One of those eight is the Elecraft-K4 reflector.
Once you're on groups.io you can browse the list of reflectors. Type in 
Elecraft-K4 and it will ask for information for you to subscribe. Then Alan, 
G4GNX. the reflector administrator will review your information and then you're 
in.
Then you will receive any emails that are posted to the reflector. You will 
also have access to the files section where you can download files that have 
been deposited there containing information on macros, answers to many 
questions about the K4 etc.
If you are interested in the Elecraft KX line, there is a groups.io reflector 
for the KX line. The KX3, KX2 and now it also includes the KH1.
If you have more questions, fire away. You can email Alan, G4GNX with any 
specific questions about the K4 Reflector.

Re: [Elecraft] K4 and Yamaha CM-500 Mic?

[George Danner]

Pete,
I'm using a CM500 that is a year or so old. It replaced one that finally
fell apart and I was tired of gluing it back together.
When I replaced the headset, I did not need to make any adjustments!

I went from a K3 to a K4 with the Yamaha headset plugged into the rear
connectors.
My Mic gain on the K4 is set at 12. TX rear mic configuration is Bias ON
Preamp OFF.

I had never used my CM-500 on a K3 so I can't do that comparison. But on 
the K4 I had to turn on the internal mic preamp and set the mic gain all 
the way to maximum.  That seemed to give about the correct level - I

Re: [Elecraft] K4 and Yamaha CM-500 Mic?

[David Herring]

Actually, I had (have) this very same problem and brought it up on here quite 
some time ago.  CM-500, mic and phones plugged into proper jacks on rear, 
preamp on, bias on, mic gain at max, mic right at my lips, and I still have to 
talk very loudly to get any response out of the ALC meter.  I got another 
CM-500 and swapped it in, and it was better…I didn’t have to talk as loud, but 
still way louder than I’d like or should have to. 

I never did puzzle out a solution for this.  So if I need or want to get on SSB 
and can’t talk loud (say like if the XYL is trying to sleep in the next room), 
I put another mic on the front connector and have no problems getting plenty of 
response out of that, even if talking in a hushed voice. 

Oscar, if you find a solution to this, please be sure to post it on here…I’d 
like for this work…failing that I might try someday to find a different 
headset/mic combo...

73,
Dave - N5DCH

I attempted to get 3-5 bars of ALC by turning up the mic gain control.  Even
with the gain up to 80, I’d have to speak *very* loudly to just get a
flicker on the ALC meter.


My CM500 mic is plugged into the rear mic jack. I turned on the 14dB 
preamp and bias. With the front panel MIC set to 15, I get 5 on the ALC 
meter with a normal voice -- no shouting or extra-loud is needed.


Don't know what's different, but those are my settings and result.

Re: [Elecraft] K4 and Yamaha CM-500 Mic?

[G4GNX]

This may sound like a silly question, but are you sure you have the plugs in 
the right way round? i.e. Not swapped over.

AFAIK this problem has not been reported on the K4 reflector and I know other 
folks are using them.

Re: [Elecraft] K4 Rx is awesome...

[David Gilbert]

He never said what kind of antenna he was using.   A lossy antenna is 
much worse on transmit than it is on receive.  You can easily tolerate 
20 dB or more loss on receive (for pretty much ANY rig) ... but not on 
transmit, especially in a contest like FD where there is tons of QRM on 
the other end.


The K4 is a very fine rig, but not because of anything he claimed.

I’ve been using my K4 at 100W (per the FD rules) this afternoon on several 
bands.
I am 1D OR.
I can hear many many stations but hardly any of them can hear me.
To me, this means that the K4 Rx is bomb-proof, sensitive, selective, and just, 
well, awesome.
If the other stations had better receivers, they might be able to hear me 
calling them.
They are obviously bogged down with on-site overload/spurii/phase noise etc.
What a pity.
I gave up replying hopelessly to CQFD’s from other 100W stations and went and 
did some woodworking instead.
Much more satisfying. Oh well….

Re: [Elecraft] K4 Rx is awesome...

[Walter Underwood]

Some practices vary with the type of contact—casual, contest, organized program 
(SOTA/POTA), event (JOTA, Field Day), DXpedition—and some are just good 
practices. This document is a good consensus description, with a lean towards 
contesting and DXpedition practices. It is called “Ethics and Operating 
Procedures for the Radio Amateur” and was developed by experience European hams.


https://www.iaru-r1.org/wp-content/uploads/2021/01/Eth-operating-IARU-ENGLISH-version3-2010-amended-2021.pdf

I also recommend the ARRL Operating Manual, though I haven’t read a recent 
edition. I actually have it ready to pick up at my library right now.

https://home.arrl.org/action/Store/Product-Details/productId/114292

The numbers are usually “serial numbers”. They start with 1 for your first 
contact and increase with each contact.

Re: [Elecraft] K4 Rx is awesome...

[Karl W Hubbard via Elecraft]

I tried driving out to my local ham fest location as indicated on the ARRL 
website, but no one was there, and then went to the past site at the high 
school football  stadium. No one was there either. 
I consider my self a newby, don’t even know the etiquette for contests or 
“interrupting” some SSB rag chews I hear on my KX3. People might assume on a 
look up on QRZ that I am an “experienced” ham and conclude that I’m one of 
those A h0l*s. I am  still having to hold a copy of the ARRL band plan in my 
left hand as I dial in frequencies and bands with my right! Reading the 
instructions as I go. No Elmer’s here. 
 Questions like: Do you or if so why do some repeat both call signs of 
participants of a QSO vs just your own? Are the numbers at the conclusion of a 
QSO “ you’re number 28” assigned by the contestant just a way of confirming or 
tabulating a QSO?
I guess it’s similar to talking to air traffic control with flying. Most of ATC 
conversation with rapid fire instructions is anticipation, but even then I had 
trouble reading back directions and squawk numbers etc. I think I must have 
some auditory dyslexia, even though my age adjusted frequencies of hearing are 
very good. 
I am limited by my antenna arrangement, and thus ability to transmit 
effectively with 100W running through my KPA100. I would think it becomes a 
sort of chicken or the egg issue when it comes to QSOs if you have availed 
yourself of all reasonable antenna options (but  I am not erecting a 60 foot 
tower in the back of my building  or mounting my 30 ft MFJ mast with 24 ground 
radials spread over the parking lot) and the only weapon left is transmission 
power. But the easier it is for people to hear you, the more enjoyable the 
radio can be and your communication skills snowball. I’m 68, and in excellent 
health, so hopefully I might have a few years at it. I am looking at taking the 
plunge next year and getting the K4D and the KPA1500 but want to increase my 
knowledge base and will need to upgrade my Buckmaster 300W 7 band OCFD 
currently in use to the 3000 W version. I cheat on CW with keyboard encoding 
and decoding on the KPX3 set at 15 WPM  although all I seem to get on the KX3 
is decoded gibberish**E*EE ** etc.
Finally, how much more sensitive is the K4 for signal reception compared to the 
fully filtered  KX3?

At W6BX, W6JTI and I, also octogenarians, worked you on at least one 
band. We were QRP with a K3/P3/SVGA, with the entire station on battery 
power.

Re: [Elecraft] K4 Rx is awesome...

The K4/at is a delight to operate anytime; this last weekend it was used 
in the /Field Day Event/


I ran mine @ 20watts on 40 & 80 meters CW via a wire dipole on a city lot///
/

Simple setup with memories programed /~  I/ /had a ball///

Thanks to the hundred that I had exchanges with

Interesting conclusion.

If the other stations had better receivers, they might be able to hear me
calling them. 
They are obviously bogged down with on-site overload/spurii/phase noise etc.

What a pity. 
I gave up replying hopelessly to CQFD's from other 100W stations and went

Much more satisfying. Oh well..

I gave up on SSB on FD more than ten years ago. Instead, have been doing 
FD QRP with W6GJB and W6JTI. There are still guys who haven't been on 
the air in the year between, and some long pauses after a QSO, but 
that's the exception.

Re: [Elecraft] K4 Rx is awesome...

[Al Lorona]

> I can hear many many stations but hardly any of them can hear me.
The most likely reason for this is operator inexperience, which is a perennial 
problem on Field Day. It's great that lots of people who don't usually get on 
the air, get on the air... but the side effect of this is a lot of really poor 
operating habits.

The biggest problem this year, in my opinion, was not identifying at the end of 
each contact. Many ops who were running on a frequency simply would acknowledge 
receipt of the exchange, then just stop transmitting and listen for the next 
caller. Here's an example:

W4---: CQ Field Day, this is W4---.
W3--: This is W3--.
W4---: W3--, I'm 2A Georgia.
W3--:  Thanks, I'm 4A Western Pennsylvania.
W4---: Got your 4A Western Pennsylvania. Good luck in Field Day!


See the problem? This would sometimes continue for 5, 6, or 7 contacts, with 
the W4 never sending his own call. So, be me for a minute: there I am, waiting 
to call the W4, except I don't know he's a W4 because he hasn't said so, and 
neither has anybody else. After the first 20 or 30 times this happened, I 
stopped waiting around for these stations to finally identify themselves.

Once, when this happened for about 6 contacts while I waited around to work a 
strong station in Georgia who refused to identify, I became frustrated and 
transmitted, "Hey, Old Man, you need to ID after each contact!"  The guy 
immediately came back, "Let me tell you, young man, that we're all Extra class 
operators here who finish in the Top 10 every year, so you're not going to 
lecture me on how I should operate!"

I went to CW after this and found the operating to be a lot better. I still 
heard the problem I just described, but not as frequently as on phone.
Another common malpractice was people who were calling CQ, and who would 
receive a response to their CQ, but then would tell the caller to send his 
exchange first. This isn't the way you do it. The CQing station always sends 
its exchange first, then turns it over to the calling station, so that the 
CQing station can acknowledge receipt, identify, and stand by for another 
caller.

I feel like we go over this after every Field Day, and nothing has ever 
changed. I feel like Get Off My Lawn Guy right now.

If you're in a club that's planning a Field Day operation, you need to take the 
April or May club meeting and help people practice the Field Day exchange 
protocol with mock QSOs. It's getting really bad on the phone bands during 
Field Day.
(I didn't mean to subtract from your enjoyment of your new K4. I hope it turns 
out to be a great rig for you for many years.)

Al  W6LX

Re: [Elecraft] K4 Rx is awesome...

[David Gilbert]

That falls more under the category of lore than science.  By all 
accounts the K4 has a terrific receiver, but of the several possible 
reasons for what you experienced your receiver is at least a couple 
notches down the list.

Re: [Elecraft] K4 recommendation - wait for HD or no?

[Ed Cole]

On the subject of two radios operating in close proximity:

I have a K3/10 (12w version) that I use with a KXPA-100 on 6m or HF.

I have noted the noise level of the K3 S-meter rise about one s-unit 
when I transmit on 2m with the IC-9700 + 100w TE amplifier into a 
high-gain 2m vertical about 100-foot away from the 3-element 6m yagi. 
K3 is on 50.125 in SSB mode, but both radios physically on the same table.


I've not been overly concerned, as trying to receive 6m while 
transmitting on 2m is not a normal operating situation for me.


K3 is updated with latest Synthesizers (two).

I suppose cable radiation could be the cause vs antenna-antenna pickup. 
Also have not tested IC-9700 harmonic output.  Testing with K3 connected 
to my 500w Bird term probably would reveal this.


Anyway thought it curious behavior for the K3 (SN 4340).

73, Ed - KL7UW
may be sort-term situation as the shack will be moved into a new 
location in a couple months with new cables and grounding.

Re: [Elecraft] K4 recommendation - wait for HD or no?

[Jim Rhodes]

Where I used to live I had a ham friend that lived about 5-6 blocks away.
When we were both running Kenwood & Icom rigs we could tell when the other
one was on the same band anywhere.  With the amps on there were times we
could hear each other on adjacent bands.  Then we each built a K3.  Then
even when pushing a little power we had to be within a few KHz of each
other to even be heard.  Since we both operated in many of the same modes
and contests we heard each other often when tuning across a band during a
contest, but by keeping a couple of KHz away we had no issues.

Back in the day, the difference between nursery take and sea story was:

Nursery story began, “A long time ago, in a land far away, ….” 

Sea Story began, “Now this is no Sh*t….”

Hello Joe,

I am in somewhat the same situation as you are, just not as bad...  I 
have a KW level Amateur living about 700 feet from me.  I had a K3, 
and as long as we were not within 50 KHz of each other, he really did 
not bother me, save when he was hammering his ALC-- but that is a 
different story...


I also have several other Amateurs all living maybe 1 to 2 mile from 
me.  All running 500 to 100 watts.


I was very worried that the K4D would have issues with any of them 
when they were transmitting.


So far the K4D had behaved as the K3 did, some interference, (not 
much), when the KW level fellow comes on line, and only on the same 
band.  I have tested other bands while the KW level ham is 
transmitting, and if I am on a different band, I can not hear him...  
With regards to the Amateur running 500 watts a mile from me, the K4D 
behaves marginally BETTER than the K3 did.


That is not the same as having another ham a one wavelength away, as 
you describe, so your mileage WILL vary...  I will NOT be purchasing 
the HD module, as it appears I do not need it...


My guess is you will see worse performance than I do, due to your very 
close proximity to the other Amateur, but I can't predict how much 
worse...  The K4D is remarkably tolerant of strong signals.

Re: [Elecraft] K4 recommendation - wait for HD or no?

[Rick Tavan]

Get the K4D now and see how it does in your situation with your and your
neighbor's operating habits. By the time the HD upgrade is available,
you'll know whether you want it. I've been very happy with K4D at Field Day
sites and in high power SO2R operation except when two stations are on the
same band.

Thanks again for your incredible patience as we've worked through the K4

I had a set of those clamps  (Vice Grips) once but I found a buyer.

while people pound on it with hammers.


My dad wanted me to learn to fly before I learned to drive and had already 
arranged my lessons.  That was a long time ago and light planes didn't appeal to 
me at all.  As you say lots of noise and painfully slow.  i was more interested 
in ham radio, fast cars and girls.  Dad learned to fly at a small dirt airstrip 
in Benson, AZ in 1946.  (I still have his log book)  His instructor was a guy 
named Neil S. "Skeet" Taylor.


Fast forward 75 years.  I have a close neighbor, Nelson, (1/4 mile away is close 
in my neighborhood) who I knew was a pilot, but I didn't know him well at all.  
Last New Years Eve another neighbor hosted a party and Nelson was there. We 
struck up a conversation, mostly about his flying  (he's a pro).  I mentioned 
that my late father had a private license, but since we were poor he didn't fly 
much and I was never interested.


When I  happened to mention the name Skeet Taylor, a strange look came over 
Nelson's face. I stopped what I was saying and in a low voice Nelson said, 
"Skeet Taylor was my stepdad."  Small world.

Yes. I tried on a set soon after they were introduced when a member of 
of our contest club arranged for their marketing guy to speak at a 
meeting. I found it to be an instrument of torture.


Several years later, after so many guys were raving about them, I gave 
them a second chance at a ham convention. They were just as 
uncomfortable the second time around.


That said, comfort level with headphones is a very personal thing, 
having to do with the size and shape of both our head and our ears. This 
product is pretty expensive, so I would urge anyone considering them to 
try them on first.

Re: [Elecraft] [K4][K3][K2] FS: David Clark H10-20 Aviation Headset

[Fred Jensen]

In addition to my regular duty as the Comm Officer at Galena AFS AK in 
1963, I also flew a DeHaviland L-20 "Beaver" for the CAP SAR missions.  
AK bush pilots never seemed to check the gas gauge before taking off so 
it was a couple of missions a month.  Not only was it deafening in 
flight, the oil filler pipe and dipstick came up between the seats 
providing, for your added comfort, a hot oil smell [and fine oil mist if 
you removed the cap to check the dipstick] in-flight.


The four headsets in the airplane were David Clark of 
uncertain vintage to which several attempts to cushion them with foam 
had been made, none of which were particularly successful.  The L-20 
cruised around 120 kts [it maxed at about 130 kts at triple the noise] 
and, since no place in AK is close to any other place in AK, I was deaf 
with a headache after every mission.

Re: [Elecraft] [K4][K3][K2] FS: David Clark H10-20 Aviation Headset

[Dr. William J. Schmidt]

I have two sets of Bose aviation headsets... the A20 and the Profilght series 
2.  Both are second to none.  Active equalization and noise cancellation... 
perfect for contests/  loud backgrounds.  They also don't fall apart like some 
headsets made specifically for the ham market.  A bit pricy though.

Hello,

For Sale:  David Clark H10-20 Aviation Headset

It’s the perfect headset for the ham who uses headphones with a mic 
boom

attached.

Perfect for use in noisy environments—the cockpit of a 172 is 
LOUD—and

when you put these on, all is quiet. The microphone ignores background
sound, and you speak close to the mic. It’s an M-7A electret mic, 
which
does need bias; the K2 needs a 5.6K resistor (probably already there 
if

you use Elecraft MH2, 4 etc.) Tested with my K4 with bias turned on.

Re: [Elecraft] K4 production software release (R32) now available

Subject: [Elecraft] K4 production software release (R32) now available

Release 32 has been beta tested (R32.BETA2) and has now been moved to
production status.

See release notes below, or on our K4 software page, or view them in the
updater on the K4 itself. (For your convenience, the list below shows all
significant changes since production release 31.)

Software development is continuing in multiple areas, including remote
control.

73,
Wayne
N6KR


* * *



 R32 (PRODUCTION) ==

December 13, 2022


- SSB/ESSB TRANSMIT AUDIO LOW-FREQUENCY RESPONSE IMPROVED:  The nominal
SSB transmit audio low-frequency rolloff can now be moved down from about
200 Hz to 100 Hz. (Amplitude at 100 Hz then increases by nearly 20 dB.)
This selection is made using the new "TX Audio LF Cutoff, SSB" menu entry.
IMPORTANT NOTES: (1) The 100 Hz selection is *always* applied in ESSB
mode. (2) In addition to using this new SSB setting, you can control the
transmit passband in all modes using TX EQ. (3) If you use USB or LSB for
audio DATA modes such as PACTOR that require fast turnaround times, you
should not use the 100 Hz SSB setting, because it slows turnaround by
about 20 milliseconds. (The high-performance digital filter required to
obtain a lower passband has additional "taps," resulting in greater
delay.)

- KPA1500 / KPA500 LOSS OF BUTTON PRESSES:  In previous releases, some amp
front panel button presses could be missed by the K4 due to the concurrent
handling of other band-change activity.

- RADIO LOCKUP DURING VFO MOVEMENT AT ~5600 KHZ:  One operator discovered
a radio lockup when moving the VFO in the vicinity of 5600-5620 kHz. This
was due to incorrect lookup of ATU LC segment data, which has now been
corrected.

- TERMINATION OF DVR MESSAGES no longer causes occasional loss of mic
audio.

- REPEATER OFFSETS are now correctly applied to VFO B when in SPLIT.

- IMPROVED EEPROM DATA VERIFICATION.



FOR SOFTWARE DEVELOPERS & MACROS


- The "TQX;" command now bypasses other command processing delays to
provide a more real-time response during "TX;" / "RX;" command
transitions.

- DUPLICATE "TX;" COMMAND while in transmit mode no longer exits transmit.

- ADDED "EE0;" command to reset all radio state and menu parameters to
defaults, with the exception of factory calibration data.

- ADDED "TQX" GET COMMAND (extension to "TQ" TX status query):  If the GET
query is "TQ;", then the K4 is considered to still be in transmit mode
during the S-meter holdoff time (300 ms), even though receive audio can be
heard. If the GET query is "TQX;", then the S-meter holdoff time is not
considered to be part of the transmit state. This allows an application to
find out more quickly when actual RF transmit has ended, which may result
in a more responsive user interface (when playing DVR messages, for
example).

- ADDED "AG$+nnn" (AF gain increment/decrement).

- ADDED "VC" command to properly handle configuration of per-mode coarse
tuning steps. "VT" command also improved to correctly handle A/B VFO
swaps, etc.

- IMPROVED "#HWFC" command to allow modification of waterfall color mode
for both panadapters on the external monitor.

Subject: [Elecraft] K4 thoughts after 3 months of use.

I ordered my K4 the first part of March 2022 and received it the middle of July 
2022. I ordered it with the 100 watt amplifier and antenna tuner.

I have a great K3S with the matching panadapter, 100 watt amplifier and antenna 
tuner. I kept this radio and promoted it to my camper.

I also have a KX3, KXPA100 with tuner and PX3. This always worked well but was 
hard to set up and get all the cords in the right places.

I have a HY-GAIN HY-TOWER and a g5rv that is only 20 ft off the ground at home. 
For camping I use a 32 ft vertical mounted on the hitch of my
16 ft Scamp fiberglass trailer. I have a 4 to 1 UnUn at the base of the
32 ft vertical and operate against the metal frame of the camper as a 
counterpoise.

I have a S5 noise floor on the vertical at home and my first pleasant surprise 
was the much lower noise floor when camping. One place had a noise floor of S1 
and the other places were S2 to S3. I think I get about the same transmit 
performance from the Hy-Tower at home and the camping vertical but I soon came 
to realize with the K3S that I was working many CW signals that were below the 
noise at home on the S Meter. I enjoyed the 4 camping trips this summer.

At home I did work on improving my operation. The better S meter on the
K4 along with the built in panadapter worked well. I found if I hooked up my 
MFJ 974H to the K4 antenna 2 and the G5RV that I can hear stations that I can 
not hear on the K4 antenna 1 which is the HY-TOWER. This seems to be true on 
all bands from 160 to 20 meters, I am having nice CW contacts that I would have 
missed before using only the vertical.

The K4 has a better AF filter than the K3 and it lets me copy CW stations with 
difficulty that do not even move the S meter. I am now working a lot more 
stations from home then I ever could before.

My only SSB contacts are on the Sunday morning 160 meter net and the SSB is 
perfect both transmit and receive and I am impressed by the contacts I make 
both transmit and receive.

The K4 sure works well with the KAT500 and the KPA500. The K4 remembers the 
tune level for the KAT500, barefoot power of the K4 and the proper drive level 
for each band for the KPA500. It is just a pleasure to use.

I find the mouse is nice to use on the K4.

I feel that having the K3S for camping and the K4 for at home is just what I 
always wanted in my 56 years as a ham. I have always like to CW rag chew all 
these years and with the exception of the ARRL field day as
5 watt battery I avoid any contests and 30 second contacts that are so common. 
I can see that the K4 would be perfect for those contacts as the fast CW sounds 
so good and the digital seems to work well even though I do not bother to make 
any of the FT8 type of contacts.

The only thing I can see that would make the K4 better would be if I could more 
easily learn how to use features that are there and I don't even know they are 
there. I am not having any luck searching the internet for help. The filters 
seem to work just as well as the K3S CW filters and of course they are much 
better than the Drake 2B, Heathkit SB102, TenTec, and Ic746 rigs I have used 
over the years. The K4 appears to be the most frequency stable of any rig I 
have owned.

I hope my observations will help anyone that is thinking of a K4 and what they 
should consider if they have a K3S.

Yours is the cynical view. I view it as more likely that it is the more

Re: [Elecraft] K4 remote software progress

[Magnus Danielson via Elecraft]

Hi Wayne,

I appreciate that update. The latest I heard is maybe 18 months old or 
so, so already this is significant update for me.


Updates will be appreciated as they come. Just seeing progress on the 
items needed to be complete is encouragement and progress, even if it 
does not give a date for beta-testing beyond what I can do with guestimate.


I see great potential with that ethernet connection in the back, and 
being a network guy doing audio and video streaming over packets (and 
others) for a living, I just look forward for it to move take the step. 
Also, it's an awesome radio with so many things in it from start, I just 
love to have the remote handling fully in the box. That and the HD 
option is for sure what I look forward to.


It was also with that background I made the comments I did.

Then, down the line after releasing remote handling, IPv6 support 
eventually needs to happen, as we soon enter into where that starts to 
dominate.


Let the team know that we look forward to test their work, be the test 
dummies and provide feedback from the field. Keep up the good work!

Hi Magnus,

I can't put a date on full remote control yet, but I can tell you that the 
entire team is working on it.

We recently completed two important pieces of the implementation -- streaming 
panadapter data protocol, and internal audio streaming paths. (The latter was 
needed both for remote and for the DVR (RX and TX. DVR for TX came out some 
time ago, but we're now almost finished with DVR for RX.)

What's left is audio streaming support and radio-to-radio meta level control 
protocol. We'll post periodic progress reports.

Hi all,

I am wondering about the K4 remote software progress. I just do not seem to 
find anything.

At the same time I want to make sure there is good and robust methods doing it. 
There is both the HTTP/3 and RIST methods, both public standards and already 
tested and available in open source. They also carry with them suitable secure 
methods to be used. I used to sit on the RIST committee and my company even 
payed for the RIST implementation within FFMPEG.

The two methods have different benefits. We've already made a test 
implementation for remote operation over existing HTTP/3 just within a browser 
Window.

Anyway, already a Linux remote would work well. As alrways preferably packaged 
as Debian packages.

Re: [Elecraft] K4 remote software progress

[Wayne Burdick]

Hi Magnus,

I can't put a date on full remote control yet, but I can tell you that the 
entire team is working on it. 

We recently completed two important pieces of the implementation -- streaming 
panadapter data protocol, and internal audio streaming paths. (The latter was 
needed both for remote and for the DVR (RX and TX. DVR for TX came out some 
time ago, but we're now almost finished with DVR for RX.) 

What's left is audio streaming support and radio-to-radio meta level control 
protocol. We'll post periodic progress reports.

Re: [Elecraft] K4: No TX power in audio based digital modes

[Mark Musick]

Dave,
This question would be better asked on the K4 reflector.
It is located here: elecraft...@groups.io. This reflector is not associated 
with Elecraft, but Bob, N6TV (one of the K4 testers) answers many questions 
about the K4 and there is a files section that contains documentation on many 
K4 subjects.

Subject: [Elecraft] K4: No TX power in audio based digital modes

New K4 seems to transmit fine in CW and SSB -voice.  But I cannot get more than 
a 2 watt  TX power out reading in AFSK.

N1MM+ w MMTTY used for generating AFSK RTTY signal.

Using the USB to PC  patch between computer and K4.

Audio TX RTTY signal is heard in K4 monitor.

PTT line functions (TX light goes on).

Low level rtty signal is heard on another rig in shack.

Under "menu", Serial USB-2 DTR is set to CW;  RTS set to PTT.

Rig control by N1MM+ seems to be working properly.

But, CW sent from N1MM+ does not key K4 in cw mode.

I imagine I am doing something stupid; I've done it before.

Thanks for any advice.


73, Dave, K2YG
