See Elecraft Builders Alert #21, October 19, 2004.
The frequency counter input transistors Q9, Q10, 2N5179 on the K2 Control
board can be low gain if the blue faced type. This gives similar symptoms to
what you have on the BFO TP2 which has a lower RF level than TP1 or TP3
consequently can cause randow readings.
Was discussed a few days back.
