November should be a great Mobile Satellite Month.
There are 7 satellites you can work from your mobile FM rig,
including PCSAT-1 which should fully recover by this weekend and
last for 2 or more weeks. So now is the time to get going with
live satellite contacts via these easy FM satellites, or setting
up a SATGATE (Igate).
145.825 ISS APRS digipeater
145.825 PCSAT-1 (recovery expected 3 Nov)
145.825 ANDE-1 (re-entry expected next month)
435.225 GO-32 +/- 10 KHz and 9600 baud
435.300 AO-51 *FM Voice* +/- 10 KHz
436.795 SO-50 *FM Voice* +/- 10 KHz
436.795 AO-27 *FM Voice* +/- 10 KHz
As you can see, there will be over 40 passes per day with 18 for
the 1200 baud satellites, 6 per day for the 9600 baud GO32 and
18 for the voice birds. All 1200 baud pass times are between
about 6 AM to 1800 local sun time in the Northern Hemisphere.
GO-32 and AO-51 voice birds are in the morning and evening,
AO-27 is in the afternoon. It is trivial to know when to
operate these birds WITHOUT A PC. Please see the
The packet path on 145.825 is VIA ARISS for all three
satellites. The path for GO-32 is VIA 4XTECH and uses two
different uplinks: 145.85 for APRS software and messages.
145.93 for all Mic-E, D7 and D700 radios.
That's more than one pass per hour on 145.825. Lots of contact
potential from your mobile...
For APRS birds:
For AMSAT birds:
For many of these satellites, you don't even need a tracking
program. Just a slip of paper on the dashboard... See:
The best antenna is a 19.5" whip in the center of your roof. 5
dBi gain on the 2m uplink and almost 8 dBi gain for the very
weak UHF downlink (above 25 degrees)...
Watch for special event info.
