Hi, Can someone point me to a website that explains the current digital modes and ways to use them? Also decoding telemetry from the birds, is there a "one size fits all" software or does each satellite have specialized software for doing this? Can you use Sound cards, TNC, specialized modems? I keep seeing references to 9K6, 38k6, and the like and have no idea what they are.
Also, are TNC's really necessary anymore? I've been away from amateur radio for over 10 years and things sure have changed.
I'm still putting my satellite station together and am down to picking antenna's and feed line. I am trying to build the station up for the future HEO birds as well, so what kind of overall db receiving level should I be shooting for?
Has anyone used "Gulf Alpha" antenna's? The cross polarized antenna's look very good to me. It wouldn't be circular polarization but I would be able to switch between vertical or horizontal with a flip of the switch.
All help appreciated, TNX 73's RoD KD0XX
