Just of interest.

Tonight I ran my tracking program and showed Atlantis was going to make a direct overhead pass. I noted the time and went out to shack and listened.
Just as predicted I heard the fast doppler on the main carrier at 2217.5MHz and followed it lower in frequency as it passed away from my location.
I am only using a so so preamp at antenna with 10db gain and a 3 1/2 turn helix. Coax comes to shack to a mixer and mixer to receiver with no post mixer amp. LO is a 2GHz generated from a 1GHz PLO locked to a 10MHz standard and a doubler.
I am not yet setup for serious spectrum display but saw the signal drift thru the display for my 10.7MHz SoftRock hooked to my IC-R7000 receiver.
This is the first time I have ever heard any signals from the shuttle.
