Yes.  I can't "tune to the P3 signal"

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.

Thanks and 73,
