My KPA 500, which is several years old, has just developed an issue which so far I have been unable to resolve.
What has happened is that when I put the amplifier into OPER, the received signal strength drops by several S units. It transmits normally and also receives normally in STBY. The issue occurred when I was changing rigs to use with the KPA500. Specifically I connected a Ten Tec Omni 6 but I cannot see how that could have caused the issue. However, the KPA500 now exhibits the same issue with my TS990 which it never has before. I believe that some considerable time ago, I did experience a similar situation and after reading all the manuals etc I found a way to resolve it. However, I have read the manual until I am blue in the face but I cannot find an answer this time. Of course I may have initiated a fault in the KPA500 but I would be surprised as it has taken all the mistakes I have thrown at it over the years and it has not so much as blinked. Any suggestions on how to sort the issue out, or what damage I might have caused to the switching circuitry, would be appreciated. Thanks in advance.
