Ghost reception

Ignacy
This has happened a few times on 20m in  WAE CW contest.

I can see stations calling on P3 but cannot hear. Or suddenly a station comes up calling CQ although I cannot see it on P3. After doing A/B twice, everything is normal. So it seems that for a moment K3 receives different frequency than it is set on.

This only occurs on 20m when somehow K3 is sensitive to high power.

SUB is off. Also only on 20m K3 sometimes does not come automatically back from transmit.  Keying is by Microham CW keyer but PTT is via N1MM in software.
