I think the problem is I don't have the K3 IF level mod [replace a resistor I think]. I finally dug out the service monitor and calibrated my K3 S-meter [after about 3 years :-)]. It had always seemed a little "stingy," as we used to say. Then I set the P3 gain to give me -73 dBm, and I had to turn it way up ... way way up. My guess right now is that it is so high that the stray signals from the K3 are showing up. I guess I'll need to make the IF mod.
