I saw a mention of an issue of folks not wanting to make a big
investment in satellite stuff to work SSB/CW.
ALL of the original ham satellites were SSB/CW birds. No FM.
And most hams already had enough equipment to get started. The
uplinks were on 2 meters or 70CM (that took a little more doing),
the downlinks were on HF or 2 meters. Some of the RS birds
where HF up and HF down, and HF up, 2 meters down. Interesting
Most folks had HF gear to start off in ham radio. I did not have an HT
until I was a ham for probably 20 years.
Nowadays there is a LOT of VHF/UHF multi mode gear floating around
the used market for reasonable prices. Also the antennas are available,
for real cheap, or haul it away for free. Keep your eyes and ears open.
You don't have to go to AES/HRO/M-squared/HyGain/Cushcraft and buy new
to work these birds. There are many old timers who gave up satellite
AO-10 and AO-13 went away, and their stuff is sitting around gathering
Hams are supposed to be resourceful and innovative!
And I went and sold my FT-847 which was about the most expensive rig I
bought! Don't need it for these FM birds, I just use a dual-band mobile
just as well.
