[Elecraft] [K2] K2 - No TX

[djmd]

Just wanted to update anyone on here who might have been curious. I believe I
found the intermittant. In the process of doing the tranmitter signal
tracing I found that the problem appeared to be between the pre-driver
output and the driver input. With the RF probe I was seeing 6v (!) on the
case of Q5 (should have been less than a quarter vrms) and only about 3mv on
the base of Q6. So I reheated and added a smidgen of solder to those
components, as well as T1 and C121. It seems to work consistently now.
