New D-Star demodulation software
A very interesting new piece of software has just been released for D-Star. It allows you to demodulate the GMSK based RF that is used by D-Star. By connecting the discriminator/packet output of a receiver into your sound card, you can see the D-Star packets including headers and data on your PC. No D-Star radio required. If you have a DV Dongle, you can listen to your D-Star repeater or simplex conversation without a D-Star radio!!!

I’ve tested it with an SDR-14/IQ using an Icom IC-R8500 receiver to tune 2M. It’s also been used on an FT897, AR5000, AR3000A.
Jakub Hruska from the Czech Republic is responsible for this AWESOME piece of software. Here’s his announcement:
Just added first version of D-Star decoder to Files section of group.
This versions can stream live decoded data to dvtool for realtime
playback using DV Dongle. It also decodes callsigns and user text or
messages (like GPS position reports).
You don't need any special hardware, just connect your soundcard to
9600PKT/discriminator output from your receiver. There are some
issues with some receivers, in that case, small modification may be
needed. If you already modified receiver for decoding trunk control
channel or for pager decoding, it should work without problems.
