Telemetry
by Tim Tapio 29 Sep '08

29 Sep '08

Hello all! Two questions on telemetry.. 1. I was considering dedicating a 70 cm "eggbeater" with a preamp as a good, omni-directional antenna. So far though, it doesn't seem to pick up below 12 degree elevations. Currently the preamp is in the shack (I know, at the antenna) and my coax is not optimum. If I use heliax, put the preamp at the antenna, is this feasible or should I plan on a steerable beam? 2. I'm having a dickens of a time figuring out what the telemetry frequencies are. I've looked at DK3WN's site which has the decoding software but I seem to be having issues finding frequencies, am I looking in the wrong places? Thanks for your time! 73 de Tim, K4SHF FM04

AO-51 L/U very cool!
by DeYoung James 29 Sep '08

29 Sep '08

Greetings, I finally decided to try L/U on AO-51 using my IC-910H, SATPC32, 70-cm arrow on a camera tripod, and a 10-elem. "cheap yagi" for the 1.267-GHz uplink. Very good signals for all on the downlink most of the pass, however my uplink on 1.267-GHz is heavily affected by trees, the fact I operate from inside my home from the 2nd floor, and I was arm-stronging the cheap yagi whilst twisting for polarization!. Great to hear Angelo, Carmen, Clare, and Mike. Thanks for calling me back in the group. A very cool mode that works very well. 73, JIm (N8OQ ex KG4QWC)

Shenzhou object number & SpaceX Falcon
by Armando Mercado 29 Sep '08

29 Sep '08

Greetings, There's been a thread on the BBS about which object is/was the Shenzhou 7 spacecraft. For what it is worth I have been using Object A keps. Central China Television (CCTV) covered the flight extensively and mostly live as it happened. Whenever they showed the big screen at mission control, my tracking program matched their screen, so it's Object A for me. SpaceX Falcon flight 4 made it to orbit. Persistence pays off. Interesting orbit. No Common Name Found 1 33393U 08048A 08273.15418783 .00071718 00000-0 92796-2 0 33 2 33393 009.3459 061.8581 0015292 250.8609 108.2346 14.79000846 26 Armando, N8IGJ
