I have 3 Visar VHF radios. Two are the same microcode level.

One of the pair, and the other one with a later level have normal volume
controls. They start out very low and gradually go to very loud as you
turn them.

The other of the pair has a problem, it goes from low volume to very
loud suddenly. If I keep turning the volume knob it gets louder and then levels off at the high volume.

Is this a broken volume control or a setting gone awry?

I noticed there is an AGC option which is not on, should it be?

The IF bandwith is set to 12.5kHz, there are two other options. I use
the radios for ham repeaters which are "wideband", should it be set to
one of the other options? If so, which one?

TIA,

Geoff.

damaged volume control.. also can be the flex but you can resolder the volume pot to get it going for a another year... use 25khz (wideband) for ham
