Thanks for everyone's comments on my T-Kit 1220 debugging. I tweaked
the CPU frequency last night, and the problem is solved.
I am now measuring the "squelch current" represented as DC at the test
point called "RSSI TP". According to the manual, I should be getting
between 1 and 1.8 volts here when a carrier is present. I am measuring
0.9 VDC with a closed squelch, and 7.8 VDC with an open squelch. I have
not tested it with a carrier present, but this looks suspicious. I will
take a look at the schematic tonight to see if I can gain any insight,
but in the meantime, if anyone has seen this problem before or has any
comments, I'd like to hear.
Thanks,
Andrew M. Moore
