What does the PA current read with the RF gain at zero and the PTT
switched to transmit?
If it is high, then that might suggest an issue with the circuitry at
the finals. Hard to guess if it is low and not adjustable.

I have a TR-4C that I cant set the bias on. When adjusting the bias
control on the power supply it has no effect on the radio. I have 2
power supplies and both have no effect. I can remove the bottom cover
from the supply and set the bias to the proper - voltage using my volt
meter but it does not set the bias on the radio. Where do I start looking.
Tnx in advance for the help....de Bill......KY4U
PS. I have checked the cable from both supplies and the connector on
the radio for loose connections but nothing wrong there.....Bill
