Raspberry Pi D-STAR Gateway

"John D. Hays" <john@...>
 

I've been working on a port of Jonathan's gateway and pcrepeatercontroller software to the ARM processor for the coming UDR56K (http://nwdigitalradio.com) digital radio.  It has been running for a couple of months on KF7UFZ gateway (currently B).

I received my $35 Raspberry Pi (http://www.raspberrypi.org) Linux computer yesterday and this evening I had a few minutes after work and copied my port and configuration files over to the Raspberry Pi.  I am successfully testing ircDDBGateway with GMSKRepeater (NQMHS board/DUTCH*Star beta firmware).  I connected to REF001C to get some traffic and successfully made contacts with 3-4 stations.

I don't happen to have an Icom RP2C here at the shack to test, but Jonathan's ircDDBGateway does support it as a controller.

CPU utilization when keyed up is ircDDBGateway 9+%  GMSKRepeater 4+%

Operating System is Debian Squeeze (both platforms), for the Raspberry Pi I needed to install portaudio19-dev

My Pi is housed in this box http://www.adafruit.com/products/859 and I'm powering it with http://www.amazon.com/gp/product/B004911E9M
