      Tony was right, it was a 2N3904.  I had my 13 year old grandson look at it under my magnifier
      and he thought it was a 2n3906 so I don't feel so bad. Now it goes into transmit and receive
      modes but  the dividers are dividing by two.  It's 108f degrees here today so I think I'll
      take a break and tackle it later.  Thanks  for your help.  At 74 I probably should stick to
      raking the yard ;^).

      When I say RX mode, I mean that is what it should be! You are not applying

      the PTT high. Q3 emitter is 12.40V, base is 6.99 and collector is 6.28V.

      I expect the other end of R34 is less than 6V69, maybe Q10 is faulty, a
      fairly common occurrence. You could remove it, or lift one end of R51 to
      confirm that the Q3 voltages are then correct.
      Ensure R50 is 22K1.
