PCSAT2 SPECIAL EVENT AND OPERATIONS
Subj: ISS Packet =>VOICE Contacts:
For the remaining days 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 / 145.800 downlink. The command station's voice
downlink will be on 437.975 +/- Doppler and he/she will
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 / 145.800 downlink, 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 in
the
evening. Passes in the Southern Hemisphere right now are from
midday.
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.
The PCSAT2 Packet system on 145.825 up and 435.275 is also
operational
as well as the 10m to 435.275 transponder (for HIGH power attempts on 29.401 MHz)... Just connect to PCSAT2 on 145.825 to bring up the transponder. Still no reports of
anyone
attteempting it or being successful.
