Thanks to everyone who replied. I am changing the voltage to 240. I tried my old radio, and I get the same problem. It seems to be a problem with the amp. I go into a dummy load with little change. A dedicated line will be run to amp for further checks. I think maybe a technician needs to check her out. It seems something not right with her.Will stay in touch. I was amazed at the number of responses.Tnx W3BJ
