I have an old Console V base station made by SBE in the '70s. Great
radio, but it's having problems -- the squelch isn't working anymore --
at least not the way it's supposed to. A fellow I know who has worked
on it thinks it's something in an IC in the radio, but the parts are
almost impossible to come by.

I have the manual and schematics -- anyone out there want to try their
hand at going through it for me?
