[Elecraft] KX3/KXPA100 issue

[David F. Reed]

I am running a KX3 into a KXPA100.

It all plays very nicely except for one issue; on a seemingly random 
basis, it seems to lose communications between them in a big way. The 
KX3 has (without my doing anything) reset the PA Mode to Off, and the 
PWR to 5.0.  When this happens, let's say I have power set to 30 watts; 
the KXPA100 shuts down and to get it back up, I have to go to the KX3, 
re-enable PA MODE from Off to On, and and reset the PWR level from 5.0 
watts to 30 watts.

My questions are:

 1. Is anyone else experiencing this?
 2. What is going on?
 3. How do I fix it

Any help appreciated.

Thanks & 73 de W5SV, Dave
