The '''[http://www.sr-systems.de/V02/content.php?show=PR430&lng=en&style=std 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. <br> The PR430 can also be used as a FM-TRX and as [[POCSAG]]-TX.

== 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:
<code><pre>
echo 438350000 > /sys/class/net/sp0/tnc/qrg
echo -7600000 > /sys/class/net/sp0/tnc/shift
</pre></code>

The FM-Tranceiver and POCSAG transmitter modes are currently not supported.
