[Elecraft] KX3-PX3-KXPA100 problem

[David F. Reed]

Folks,

up til today my combination in the subject line has worked flawlessly.  
Today a couple of problems surfaced.

(1) the power switch on the PX3 is intermittent for ON, always works 
OFF.  In other words, it does not always power ON when asked to, but 
always powers OFF when requested to.  Not a big deal, but would be nice 
to fix...

(2) the KXPA100 would not come on; in trying to track it down, I observe 
that the PA mode in the KX3 was OFF; setting it to ON, the KXPA100 turns 
on, and the Sys Fault LED flashes, then it turns off the KX3 PA mode and 
itself OFF.  Big deal, and would love to fix it.

I have rechecked all the cabling and removed and reinserted it i to no 
avail.

Thoughts or suggestions?

Thanks & 73 de Dave, W5SV
