The PR430 is a small device integrating a TNC and a 70cm 6W-transceiver optimized for packet radio (1200 Bd. AFSK & 9600 Bd. FSK) use. It is connected to the host system through an RS232 interface using the common 9-pin sub-D connector. It is running enhanced 6pack as the line protocol.
The PR430 can also be used as a FM-TRX and as POCSAG-TX. It was developped by the German company SR-Systems.
Linux support
Currently Linux does not support enhanced 6pack, therefor special drivers patches are needed. The patch is available at http://www.linux-mips.org/pub/linux/mips/people/ralf/pr430. The enhanced 6PACK driver is configured via sysfs. To configure the (first) device to a receive frequency of 438.350MHz with a shift of -7.6MHz use the following commands:
echo 438350000 > /sys/class/net/sp0/tnc/qrg
echo -7600000 > /sys/class/net/sp0/tnc/shift
The FM-Tranceiver and POCSAG transmitter modes are currently not supported.
