[Elecraft] K3 and linear amp

[hank k8dd]

Bob speaks the truth here.  The K6XX fast relay circuit
is the answer.
The problem with Elecraft rigs switching Ameritron amps
has existed with the K2/100 and, so it appears, now with
the K3/100.  
I have had the K6XX fast relay circuit in my AL-1200 
working with the K2/100's.  No KPA-100 shutdowns 
since I put it in a couple of years ago.  And there has
been no problem with the K3/100.
It is a simple fix to allow the K2/100 & K3/100 to work
with the slower 12VDC Ameritron amp relays ..... if you 
need it.

Go to this site http://www.k6xx.com/radio/fastrely.pdf

K6XX has a need relay speed-up circuit that might be
applicable to the relay in your amp.  I suppose that it
requires the relay to be a 12v relay, though.  Don't
know what you actually have.

Good luck and 73
