ARISS and PCSAT status
At about 2015z, here is what I am seeing on ISS and PCSAT:
ISS is doing well on 9600 baud on 145.825. A nice amount of activity. Looking at the live downlink on www.ariss.net it is easy to see that we do have some good 9600 baud Igates passing the 9600 baud data into the APRS system. Over the last 4 hours I see these IGates:
qAS,KD8CAO-7 qAR,K7MT-1: qAR,K7OFT-10: qAS,PA3GUO: qAR,ST2NH: qAS,DF9CP: qAR,PD0RKC:
After 7 years, PCSAT is not waking up as bright and chipper as before. For the third day, we got control, but this time, she did make it through a full orbit. Last telemetry packet was T#212 or 212 minutes of uptime. We have DIGI OFF while it recharges. BUT, as of this writing, we have not seen anything on its web page downlink for over 4 hours.
Either we do not have enough Igates on 145.825 1200 baud, or it has crashed again. It is easy to see on http://pcsat.aprs.org. If the telemetry number is above 90 then it has run a full orbit since the last re-start. When we change the callsign from NODIGI back to PCSAT-1, then it will be open for digipeating. Details on www.aprs.org/pcsat.html
When PCSAT returns to user service, please review the user-service-agreement on www.aprs.org/pcsat/contract.txt particularly we do not want to see any unattended beacons cluttering up the ISS/PCSAT channel on 145.825. Let the live users communicate.
If any dual-hop opportunities arise, the best PATH to use is VIA ARISS,ARISS since both satellites support that alias, and both satellites will do their callsign-substitution if successful. The normal APRS path of WIDE2-2 will also work, but last time I tried it, the RS0ISS did not insert it's callsign, so you had no proof that it went via ISS. SO use ARISS,ARISS for possible two hops. Best place to look is at AOS on the west coast (if the one person in Hawaii is actually transmitting) and at LOS on the east coast if the geometery of a conjunction will get to Europe.

All,
As of 11-Nov-2008 2315z KD8CAO-7 has gated 307 ISS 9600bps packets received from 26 unique stations.
Summary:
8-Nov-2008 1 packet from 1 station 9-Nov-2008 42 packets from 8 stations 10-Nov-2008 152 packets from 16 stations 11-Nov-2008 112 packets from 21 stations
FYI: KD8CAO-7 is a Kenwood TH-D7A, attic mounted dipole antenna fed with 50' 1/2" Andrew Heliax, and Alogger 3.2.0 software.
Thanks to those who are also IGate'ing ISS 9600bps packet.
I hope to work you via ISS in the days to come.
73,
Doug KD8CAO
