About the only 3 'internal' things that would provide no audio are:
?* The TX potentiometer R1
?* JP8 installed.? This is only needed for "some" HTs.? Not with radios using the Data Port.
?* TX amp which you are able to change (increase) using CALIBRATE.
If it isn't one of those 3 things, then it must be the connection between radio and TT4.
At least that's all I can think of.

Using CALIBRATE get a red/TX light, but no sound heard when monitoring with another radio, no matter what setting.
Using MONITOR, no sound heard no matter what setting.
I have an idea what might be wrong, but will withhold that idea from here until others offer suggestions, to see if i am thinking the same.
