[Elecraft] Trouble with K2

[Luc Favre]

Godd evvening,
My K2 suddently got mute. I suspect it get a too large RF signal from my
other transmitter, but when ?
Now in Rx mode, no signal comes in. A signal generator in the 7 Mhz band can
be geard but not moved with the main knob. The frequency display changes
from band to band varies with the main knob.
For I suspected a SW trouble I reinitialized the K2 (4-5-6). OK. I then
proceeded to a call pll on 40 with the probe lead in TP1 : info 232.

Any idea ?
Thank for your help + 73
