Check the connections on the BNC cable between your K3 and P3 and re-seat them.
Also, if you have an extra BNC-BNC cable, try replacing this cable.
Also, if this BNC is run near switching power supplies etc. it can pick up noise
like this.

I have a 8-9 khz wide signal that follows my VFO A around. I saw this on 160m
and also in 10m this morning. I haven't checked the other bands.

No antenna was connected to the K3. The only cables connected to the P3 were:
Coax and RS232 from K3. I attached the RS232 to the computer to get the snap
shots, bet the signal did not change with it connected to the computer or not.
Note: During the snapshots I bumped the VFO knob from 28.120 to 28.119.40 by
mistake during the snapshots, but that doesn't have any effect on the fact
there is this big wide scary 8-9khz wide signal ~ 30 khz down from VFO A that
is tracking my main VFO.
What is going on, has my K-Line been invaded by something? If so what and how
do I fix it?
