Re: [Elecraft] Any progress on K3 modules?

[Wayne Burdick]

Hi Pete,

I just rechecked status on these boards. It looks like the KSYN3 will be the 
first one to be manufactured. I'm not sure about the KIO3. Unfortunately all of 
these modules (like everything from toasters to Teslas) are subject to supply 
chain issues, and in most cases just one or two parts are holding things up. 

As each board comes out of the queue we'll post updated status right away.

[Elecraft] Any progress on K3 modules?

[Pete Smith N4ZR]

Has there been any progress on the planned final production run of the 
KIO3 Upgrade Kit?  I ordered one just before everything stopped in 2020, 
and put my name on the "last chance" list in 2021, but have heard 
nothing since.

Re: [Elecraft] KPA500 Parts

[Lyle Johnson]

7.5V

It is not there to regulate, but to limit in case of something bad
happening, while allowing the gate of the FET to get the full control
voltage for T/R switching.  The zener normally is not conducting.

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.

Cheers,
Magnus

[Elecraft] KPA500 Parts

[Andy Durbin]

"The latest revision of the schematic for the KPA500 TR Switch shows a Zener 
diode at the gate of Q4 in place of R3, the 100K resistor previously."

What is the latest revision?  I have Rev D which is later than any I have found 
on-line but it shows R3 not a Zener.

[Elecraft] K3 serial port

[Pete Smith N4ZR]

Thanks to everyone who offered educated thoughts on my problem.  I just 
discovered that the problem apparently lay in my USB hub, perhaps as 
simple as a loose connector.  I plugged the USB cable into a computer 
port directly and voila!  So I now have frequency control communications 
again.  All I'm lacking now is to clean up the Windows registry and, 
hopefully, be offered a good port again for my CW/Other function, so 
that I'll be able to send CW from the keyboard.

Re: [Elecraft] Diagnosing Serial Port Issue

[Stefan Jansen]

Hi Pete,

First of all, the „active“ part of the USB cable is the USB-to-serial 
converter. This communicates with your computer even if the cable is not 
plugged into your transceiver. So to find the root cause, I would not plug in 
the transceiver end of the cable at all for the following:
1. Open the device manager on Windows, maybe the easiest way is typing „device 
manager“ into the search field of the start menu.
2. Plug and unplug the USB cable and  observe the entries under COM port s and 
see if a port appears and disappears. This way you can find out which COM port 
is the one you have to use in your CAT software.

If you cannot find a COM port in that way, Windows might not associate the 
correct driver to the converter in the cable. In this case, maybe consult the 
manuals or re-install a current version of the FTDI USB-to-serial driver.
