The PCSAT2 packet system is enabled for both 1200 and 9600 baud digipeating, and it can also do cross-BAUD digipeating. That is 1200 up and 9600 down or 9600 up and 1200 down. We had no specific application in mind, but it
is there for experimentation.
For 1200 or 9600 use the path VIA ARISS. For cross-BAUD operation use the path VIA XBAUD.
The easiest way to experiment is to use either the Kantronics KPC-9612+ TNC or the Kenwood D7 or D700 that can both easily switch between 1200 and 9600 baud.
Experiment with the shortest TXD delay you can get by with at 9600 baud. Typically for one-at-a-time packets like APRS, there is not much advantage for operating at 9600 baud, because the TXD delay is often as long or longer
than the data, so the actual throughput advantage of 9600 is more like a factor of 2 than 8.
Perhaps the value of operating at 9600 baud would be in downloading Mail from the PCSAT2 PBBS. That is the only time when all the delays will be amortized and 9600 baud would give you a significant throughput advantage.
Users are welcome to use the PCSAT2 digipeater for experimentation.
Uplink is 145.825
Downlink 435.275 +/- 10 KHz Doppler
DIGIpeater call is ARISS for 1200 or 9600
DIGIpeater call is XBAUD for cross-baud
PBBS callsign is MAIL-1
The Kenwood D7 and D700 can do either 1200 or 9600 and on either band, but not both baud rates at the same time. The KPC-9612+ can transmit either 1200 or 9600, but because it is dual port, it can receive both at the same
time.
