> 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
> 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
> 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.
