[Elecraft] Lost Tone

[Alan J. Price]

Hi:

The sidetone was there, honest, but after finishing the K2 and amp it was
gone. I have �0� VAC at pin 25 of U6 on the control board when I key the k2.
Did I wipe out the micro while making the modification for RS-232?  The
RS-232 function does not work either; all else is great, full output with
the amp etc.  Aside from that Mrs. Lincoln, how was the play?
