My guess is a cold solder joint somewhere, but I dont know where the squelch portion of the circuitry is located. (And I cant find any service manuals. Google has failed me.....)
It doest happen often, so I dont really feel like its worth it to reflow a bunch of components and hope it works, but if somebody knows a specific point worth looking at, I'll give it a shot.
But it is kind of a PITA to have to get out of my chair to just to give the pager a squeeze

(Oh, and is the squelch level in the M3 set on the board, or is it a softpot in service mode? I wouldnt know, as I only have the DOS PPS.)
