[Elecraft] K3 problem

[Don Wilhelm]

Jim,

Check the power supply to see if it is shutting off - if it not that, 
try the K3 into a dummy load.  If the problem goes away with the dummy 
load, the most likely reason is RF in the shack.

I did not think I had a problem with RF in the shack until I recently 
tried working on 10 meters.  At power levels above 75 watts, the K3 
would turn off all by itself - but no problem into a dummy load, so I 
have to get some ferrite on that antenna.

If RF is causing it, take heed of the wealth of information for 
attacking it in K9YC's paper on dealing with RFI at
