[Yaesu] FR-101

[DAN COTSIRILOS]

I have a very strange case here? This radio was purchased new and never really use. I got this from a very reliable ham friend of mine and it was working to some degree as far sensitivity is concerned. It acted like typical tarnished contacts in the band switch? I can't get it back even to the sensitivity that it had the first time I heard it? I put a metered signal gen on it and 3 volts is about S-9 on 80 meters. as you go up in freq the meter readings increase to 40 over 9 with the exact same input volts?? Here is even a crazier part the s-meter shows a higher ready with the int calibrator on the lower band than the higher?

anyone have clue what could be wrong???
