[Elecraft] Tunable carrier (birdie) 20445khz

[Ron D'Eau Claire]

I show one birdie here. It's a "normal tuning" (not double rate) birdie which, with great respect for Don, I will disagree with him and say that not all birdies tune at accelerated rates if one defines a birdie as an internally-generated unwanted signal. That birdie is at about -100 dBm.

If I turn on the preamp and connect a dummy load, a row of lower level birdies does appear, but they are completely buried in normal band noise (here at -140 dBm) with an antenna connected. 

As others pointed out, you can try moving TMP cables or, more simply, applying the "birdie removal" software. The latter does not cause a hole at that frequency. It just moves the oscillator frequencies around as you tune to that frequency so that when you are tuned there the birdie is somewhere else.

Thanks for the suggestions guys - for those of you with P3's - tune to
20445.11 on CW nor mode and take a look with the span on the P3 set at
200khz. A regular picket fence of birdies! (at least on my K3)
