PCSAT2 special Operations Event PLAN update



This is a  late post, since AMSAT-BB has been bouncing all my mail...

ARISS Packet was not on during the morning pass over Eastern USA,
We maintained the voice downlink on 437.975 and despite being
busy manually moving two arrays, and 3 rigs and keeping the
motor mouth busy, it worked.  Below is the description of this
test (with earlier typos corrected).

PCSAT2 SPECIAL EVENT AND OPERATIONS
--------------------------------------------------------------
Subj:  ISS Packet =>VOICE Contacts:

Starting on 4 August, and for the 26 days remaining of
PCSAT2's operation on ISS, PCSAT2 will be configured for
VOICE response to normal packets transmitted via  the normal
ISS digipeater 145.99 uplink (or PCSAT2's uplink on 145.825
if the ARISS packet system is not operational).  The command
station's voice downlink will be on 437.975 +/- Doppler and
he/she willl attempt to acknowledge  by voice all packets seen
on the packet uplink or generally chat about the system.

The UHF downlink will be weak (only 1 Watt) and being
UHF (9dB worse than 2m), will need at least a small
beam to hear it.

Users who want to participate, simply send your packets
as normal VIA ARISS on 145.99 uplink (if available or via
145.825 if not) but listen on the 437.975 downlink for the
combined voice and packets.  This will only work when
PCSAT2 is in range of a participating command station and
there is no guarantee that all command stations will be available
on  any given pass.  In otherwords, this may be rare, but fun.

Right now, passes in the Northern Hemisphere are occuring
before sunrise, so only the last two morning passes may be
so manned for voice.  Passes in the Southern Hemisphere
right now are from midday into evening.

Best thing to do is simply monitor 437.975 during ISS passes
and if you hear a command station, then send us a 'hello'
packet via the  ISS (or PCSAT2) digipeater.

We need a volunteer command station in South America,
South Africa and some other footprints too if activity is
desired in those areas.
