> 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.
