K3: defective ant.relay?

[Richard Meilstrup]

My K3 (ser.no. 2994) has suddenly started behaving strangely: When CW-keyed
by N1MM (and sometime also by Logger 32's CW-machine, but not as often!) the
TX goes "brrrrr...." (TX interrupted 100 times/second). Now lately, the RX
seems to go dead (no signal in) until I activate the key.   Do I have dirty
ant-relay contacts? Must the relay be changed?

Rick,

This usually happens when the cable between the computer and K3 gets some
HF. Have you tried some turns on a ferrite ring or a clamp?
