I used to : work it from my mobile station, but have had to give it up due to the : large number of high power base stations with large uplink beams using it : for passing recipes etc. On the rare occasions when this satellite is : not cluttered, 4 W talkies with rubber duckies can work each other. I don't work AO-27 much.. : AO-21 is much worse because it has been around longer. The regulars on : this one use 40 el uplink beams and 1 KW plus amplifiers. The downlink : is 145.987 Mhz FM and the uplink is 435.016 Mhz FM. C'mon.. that's a bit of a stretch.. Most satellite stations, mine included run 50-70 watts uplink into a regular satellite antenna of about 9 elements. Get real, you _can_ work this bird with a handheld, but when you have a nice satellite setup, the handheld doesn't cut it.. Even I have trouble with AO-21 from time to time, so the secret to working this bird is keep trying! I have called CQ on 21 and nobody answered - just the right (wrong) time of day and nobody was on but me, and that's what I call having your own satellite :-) : For info on the other birds you mightr pick up a copy of "The Satellite : Experimenters Handbook".
