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.

A regular picket fence of birdies!
