Allen...
I have these same birdies (at least I suppose they're the same) and
I suspect that all K3 have them. The most annoying ones are where the CW
action usually occurs (50.09430, 20 dB above noise floor) and a number
of minor ones around 50.098 (3-5 dB above the noise floor), as well as
several major ones up where the SSB action occurs: 50.21050, 50.24055,
etc. which are all 20+ dB above the noise floor. These are not
"external" blips (not computer, not router, etc.) as they are present
when nothing else is on, and they are present when the antenna is
disconnected.
I "treat" them by ignoring them. They are sharp, stable, and
unmodulated. My ear can differentiate between them and real signals
without any problem. They are "features" for "calibration.".. ;>) Every
modern rig I have ever owned has had similar warts.
