I took Farhans advice and went over every trace on my digital board. Cleaning between traces under a microscope and now I have 5v on pin 5 of the digital board. My display reads: A= 14,2000 RX. And the second line reads: USB RX 0t!. But I'm still stuck in transmit. I measured the voltage on the 47k resister feeding the base of Q23, on the digital board side it is 3v on the base side of Q23 it's .57 Should I change that back to a 4.7k? What should the voltage be at that point?
