Make sure your BNC cable between the K3's IF output and the P3 input is
securely plugged in. (I usually unplug and replug in the cable as part of this
test.) If you have an alternate BNC cable, try it too as its always possible
there is a poor connection between the cable shield and one of the connectors,
allowing external noise to leak in at the K3's IF frequency.
Also make sure this cable is not placed on top of switching power supplies or
near other possible noise sources.

I've noticed a large number of "phantom" signals on the P3. They look like
signals but when I turn the RX dial, they move along with the cursor. When I
turned the P3 off and then on, they went away of 40m but that same thing
didn't happen on 15m. Any ideas?
