ALL, unique problem.. radio recapped. working great with good rx and tx.. then after about 1/2 hour or so..channels of 4,8,12,16,20, and 23 kind of stopped working... but not really .. signal via signal generator went from s7 down to about s3.. also tx power went down.. all other channels are ok.. only thing common to all those channels is a 8.533 mhz xtal.

can a xtal heat up and stop working somewhat?

very baffled with this one i can post a schematic if needed..
