[Elecraft] KXPA Firmware Download Problem

[Dauer, Edward]

Dick and David  --

Thanks for your good counsel; I do appreciate your taking the time to help.

I’ve solved the problem but in a way that defies explanation.

On a hunch I decided to reload the F/W in the KX3.  I know that was up to date, but because I use the KXPA PC connection to connect the KXUSB to the computer for both the KXPA and the KX3, I thought  . . . well, it can’t hurt.  But momentarily it did hurt.  Trying to reload the KX3 F/W with the KX3 Utility resulted in a hang up.  Unable to shut down without removing a battery, and then experiencing a continuing hangup even after the manual’s suggested restart.  Multiple times - the Utility reported no communication between the computer and the KX3.  So, on another hunch (or out of desperation) I unplugged and reseated everything and then I reloaded the KX3 utility – even though the one I had on board is the latest.  Did that; tried the F/W reload on the KX3; and that worked.  Then back to the KXPA Utility, tried to download the new F/W rev for the amp – and that worked!

And people say the business I’m in is mysterious and arcane . . . .

Many thanks.  Hope you had a great holiday.  See you in the CQWW CW.  I’ll be on with an updated KX3 and KXPA.
