Hi all,
Having just got my 2.4Ghz down converter going I was wondering if there is
any
signals space-side besides AO-51 and the lunar orbiter that I could go and listen for ?
regards
Tim

Hi Tim, VK2XTT
Depending on the gain of your antenna and the overall Noise Figure of your receiving system, you can try to receive the Sun Noise at 2400 MHz
Using my 4 ft parabolic dish ( gain = 27 dBi ) and my receiving system with an overall Noise Figure = 0.98 dB I get actually about a (S+N)/N = 3.5 dB of Sun Noise with the actual solar flux of 66 sfu at 2800 MHz
Receiving Sun Noise tell you if your receiving system is working or not according to your antenna and receiver specifications because our calibrated noise source at no cost is the Sun.
By the way a little of Radioastronomy at 2400 MHz is all we can do waiting for P3E
If you are interested on it please let me know.
