[Elecraft] K3/P3 DOA

[Randy Farmer]

My P3 worked well for less than 24 hours after assembly and then 
developed the same symptoms. It turned out to be a failure of the MMIC 
amplifier device on the RF/Splitter board. I did a board exchange and 
it's been running fine for several months. Perhaps there was a bad run 
of these devices, as I believe I've seen a couple of others mention a 
similar problem. Elecraft support will certainly make sure he gets the 
P3 up and running ASAP.
