I replaced Q2 and now I have the voltage on R16, and I am able to change the
Receiver RF Ap bia. Starting it off at 179 mV. I am able to get it above
200 with no problems. One transister off, at least I have two good
transisters nwo.
Updating the Schematic now for the IF and Control circuits.
I plan on getting this up on the air tonight, maybe in time for the local 2
meter net.
Thanks for helping me out, this really gave me a good look at the circuits.
I will write some notes on it.
I will look at the correction you mentions abt the circuit board. What
effect does that have on the operation of the unit if left as is?
David
