Folks,

I have a VFO/display problem with my Panasonic RF-3100.

However, all of a sudden, I lost the portion of the broadcast 88-108 mhz
FM band. At a point below 95.7 mhz the display turned to 9989.3 and
would not tune lower. Above that frequency the FM band works fine,
as does the full range of all the other bands.

Does it pick up signals and just not display the frequency? Or
does it quit working below that point?

In the first case, it's probably the circuitry that converts the
local oscillator to the digital signal that feeds the display
electronics. (Buzzword: Prescaler). Or the oscillator is weak
and not providing enough signal. (For the second case, the tuning
capacitor the other poster mentioned is a strong possibility).

I had a several similar problems in my similar vintage Kenwood
R-1000. The first case was a poorly aligned filter on the
frequency synthesizer board, the second was a bad connector in
the power supply, and the bandswitch needs a shot of tuner-lube
every five years or so.
