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.
