From: "Bob Bruninga" To: "TAPR APRS SIG" ; Subject: [amsat-bb] PCSAT2 (prototype) on AIR Date: Friday, May 23, 2003 17:21 PCSAT2 prototype is on the air in Annapolis, Maryland (USA) and may be workable out to about 10 miles. We invite anyone in range to please experiment with its three transponders: * APRS/UI digipeater (145.825 up and down) * PSK-31 transponder (10m ssb up 435.250 down) (see note below) * FM Voice repeater. (145.800 up 437.975 down) See: http://web.usna.navy.mil/~bruninga/pcsat2.html We need your help to test it thoroughly so we can fix any bugs now instead of living with them later. Like PCsat, PCSAT2 has no control system other that the basic KPC-9612+ TNC. Thus we used the CONNECT LED as the simple means for USER control of the transponders. This way, anyone can turn on a transponder and the connection-time-out process gives us an automatic time out 8 minues later to save power when it is not in use. NOTES ABOUT THIS TEST: 1) To provide some signals for the PSK-31, the HF uplink is not on 10m but is being fed by an external 20m receiver listening to 14.070. We do not expect you to try to transmit, but just have something to RX.. 2) TELEMETRY is running at 4 times the rate we will use on flight. 3) To give you something to do, we activated the PBBS. Its call is PC2BBS. This is NOT normally going to be used on PCSAT2. But is an easy way to test the packet system. 4) Next week, I will release a telemetry decoding and display program.
