[Elecraft] KSB2 No Transmit Audio

[Beth Wenzel]

Hi guys, i built my k2 about a year and a half ago, I've recently decided to add a Ksb2, all wen together well, but... alas it doesn't work. I've checked all of the signal voltages, everything is ok. I've traced (with an o-scope) a nice looking modulated signal to the top of D3, then nothing. Checking D3 in circuit it looks ok (.6 ohm forward, > 100k reverse) I'm assuming the sig should pass through to the base of Q3 (?).

Is there a circuit description that can help me with the trace?
