buckskin,
I misinterpreted a couple of your statements which led me to suspect T1.
I was wrong, and as nomad said, T1 is not your problem if you have PA function and can hear the weather stations.
since the one part that could have explained both of your problems is not the culprit, we need to back track a bit so that we don't have any future misunderstandings.
let's check the radio once more before we start unsoldering things.
first, you are going to need a working radio set up next to your broken radio so that we can see whether or not the broken radio is receiving signals or not.
so, set the broken radio up like this:
noise blanker and ANL OFF.
volume up all the way. (clockwise)
squelch down all the way (counter-clockwise)
RF gain up all the way.
meter switch in S/RF position.
known good microphone plugged in.
antenna connected.
set the working radio up near the broken radio, on the same channel, dynamike all the way up, antenna connected.
now key the working radio (or have a helper do it) and watch the needle on the S-meter on the broken radio.
did it move?
it should have moved over towards the far right side of the meter, and probably shake around a bit when talking into the working radio.
once we know what we are dealing with, we can tackle each problem separately.
