The intermittent (cold rig only) problem cited below completely disappeared
upon removal of the NB and SSB boards (replacing them with the requisite
jumpers and the capacitor). The KSB2 board was put back first and the rig
still behaved perfectly. However, when the NB board was plugged back in the
problem returned (note - the NB function is turned off). Interesting that
both RX and TX are affected. More to follow...

Trusty K2/100 SN#583 has a problem which is the first significant issue
since building the basic K2 in Oct of 1999. The rig 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?
