: I am trying to figure out how to listen to radio signals from space. : Kurtz.

Hey, Kurtz! I remember reading a book about 20 yrs. ago that discussed tracking and ID'ing satelites by some ID signal they transmit. It seemed pretty easy, like making a dipole antenna out of coathangers or some such, and the receiver was either an AM or short wave radio. I dont recall what the title was, but I'll try to find out for ya. In the mean time, try some ham radio websites, I'll bet you'll find more than you ever wanted to know. Also, ham operators with high power sets actually do a 'moonbounce' to reach fellow operators on the opposite side of the globe, you might tune in to some of these signals with SW. I don't know how you'll be able to tell a moonbounce from LOS or atmospherically propagated signals, except maybe an echo effect, one sig from the 'bounce, and one local.

Good luck.
