Well, it seems that AO-27 is back in the analog FM Repeater mode. I worked VE7VVW Ron (*) on Saturday afternoon; he had a really nice signal, subject to the characteristic AO-27 fade. "The Fade" is possibly my problem in not having a circular antenna, but the effect is that a signal will be Q9 one minute, and inaudible the next. Having said that, I wasn't able to hear the bird on Sunday, so maybe it's schedule is still somewhat erratic. Greg KD6KGW (*) I've heard Ron for some time on several satellites, but it wasn't until Saturday that I understood he was Ron in Vernon, BC, instead of Vern in BC. :-) ------------------------------ Date: Sat, 05 Nov 1994 14:32:01 EST From: w1aw@arrl.org Subject: ARLK049 Keplerian data SB KEP @ ARL $ARLK049 ARLK049 Keplerian data ZCZC SK17 QST de W1AW Keplerian Bulletin 49 ARLK049 From ARRL Headquarters Newington, CT November 5, 1994 To all radio amateurs SB KEP ARL ARLK049 ARLK049 Keplerian data Thanks to NASA, AMSAT and N3FKV for the following Keplerian data.

Good idea, unfortunately the commercial geosat boys aren't interested in letting us piggyback, and when AMSAT finally figured out what our own geosat would cost, the gasp could be heard around the world. :-) Looks like ham geosats will have to wait a while longer.
