[Elecraft] Firmware, K3, large jump AB3JN

[Keith Trinity WE6R]

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!
