[Elecraft] K2 RX/TX Problem

[JohnK1JD]

Trusty K2/100 SN#583 has a problem which is the first significant issue since building the basic K2 in Oct of 1999. The has been mostly unused (neglected?) since the K3 arrived last November, but decided to fire it up the other day and discovered that both RX and TX exhibit a broadband 'hash' sound instead of distinct CW when first turned on, both on signals received and on its transmitted signal. This problem lessens as the radio warms up and eventually disappears completely. I have used it quite a bit this weekend and it's been fine - until I turn it off for a few hours.

The frequencies for the VCO and BFO seem OK as do the voltages. Cal PLL was performed and completed without any errors.

Has anyone experienced this intermittent problem before?

Thanks & 73,
