The two astronaut-hams also spoke to cosmonaut Anatoli Artsibartski, U6MIR. The contacts were made on two successive passes overhead. Jay Apt said ''Ken is my friend and former STS-37 crewmate. It was terrific to hear his voice after several months corresponding by e-mail only. What a great way to use ham radio.'' Cameron and Artsibartski were standing near the Star City statue of Russian cosmonaut Yuri Gagarin, using a hand held transceiver and 5/8 wavelength whip antenna, standing on a car to increase their elevation, astronaut Jay Apt related in an Amateur Radio packet message from space.

Thanks, Paul. That looks like it will be my first shot. I've got an Isopole for 2M so I'm set. 29 MHz antenna is an R-7. From my location, RS-12 is much louder than RS-10 even though both are 10M downlink. HF rig is a TS-690, so the receive should be pretty good. Any reason for the disparity that you know of? Are you using a pre-amp? Any suggestions?

What are my options for satellite work? I don't mind adding hardware in the shack, but the stuff outside will be limited to dipoles, verticals, etc. Present equipment includes HF, 2M, and an old TNC-2 clone. I'll probably be replacing the TNC shortly, but the 2M is an Icom 251A and it will most likely be staying. Upgrading will be piece-by-piece. Suggestions are GREATLY appreciated.
