Ron, Check your keying line from the Flex-5000 to the KPA-500. If the PTT line is not connected I would expect to see the problem your experiencing, Jim K2ZF

Got 500 watts out on 40 to a dummy load and everything seemed ok. Powered the rig and amp off then on and all of a sudden get only 35 watts out for 35 in. Does not matter what band I Put my rig on as I only get out what I put in. Don’t see any errors and the amp is in OPER. There are no faults BTW. Anyone have any thoughts as to why I no longer get any output from the amp?
