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
