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? Jerry
