[Elecraft] KPA-500 Switch from STBY to OPER

[afpacker at gmail.com]

I am looking for thoughts and suggestions to diagnosis what I am seeing.
When the amp is changed from STBY to OPER the receive signal drops by
multiple db and the general background seems to increase significantly. The
tuner seems to work the same with or without the amp. When I transmit it
appears I am getting full power output. I am driving the KPA-500 with a K3.

 

Thanks in advance
