George, 

Thanks,  

And my problem is different and I have solved it.   I am feeling silly…    My antenna switch was not on an antenna.    Sorry for the bandwidth.

Hoop,
I had a similar problem several years ago.
It was a bad BNC cable on the K3 to P3 IF cable. One of the ground 
connections was poor at the connector.
Try "Wiggling" the cable to see if it changes or goes away or even gets 
worse.

Folks,

I’m just seeing, today, that there are “birdies” for lack of a better term 
that appear on my P3 and which track my VFO and which are up 50 to 65 Khz up 
from where VFO A is located.   This wasn’t happening yesterday.    There are 
four lines about 5 Khz apart.

What factors might be at work that result in this phenomenon?   The second 
question would be, what to do to remove them?
