[Elecraft] Firmware, K3, large jump AB3JN

[Joseph McIntire]

Yes that is  what happened  I just  loaded  the latest FW the mcu and FPF firmware  update  went well but when it loaded the  DSP when it restarted  the radio for some reason it didn't  recognize  the 2.88 version  it had just installed.  You know  question marks ??.?? For the installed version  for the  DSP. The others  look  ok. And I get the ERR AT3. I have not searched  yet for other trouble codes.  I am at work right now.  I will  look at it again  when I get home.  I have  been  going through the release notes but  there is a lot to  go through. I will  look into  the parameter reset  also. I will  let you know how it goes.

Hi Joe;
That is a HUGE jump! ( from 1.96 to 5.67. The oldest I have seen come in
was 1.30!!)
It is rare, but I have seen a glitch or two in extreme jumps.
One is the ADC REF gets set to an invalid voltage of 4.00 which is OUT
of RANGE!!
Also any saved configs you might load could be an issue if you re-load.

I can send you some in-between FW, but it is a LOT OF WORK and is NO
guarantee that glitch won't happen.
Is there some feature that you are specifically avoiding??
If you don't go with the latest, the Manual etc will not match, nor
would any discussion with CS or other folks that are current.
Reading the release notes is an excellent idea if you want to look for
something specific, or ask me or CS.

I *HIGHLY* recommend loading the latest FW and then after do a
"Parameter RESET", (EE-INIT-ialization), and then setup and calibrate
from SCRATCH.
(IE don't load an old config).
**That is what I do in repairs (after checking with customer) for such a
large jump in FW.
Also, that old of a radio will need gold pins and MANY hardware updates,
feel free to send it in so I can get my hands on it, hi hi!
