[Allstar Digital] [App_rpt-users] DMRGateway

[Steve Zingman]

Mike and I spoke about this last night. The way we see it, it's not much 
different then a home brew D-Star repeater.
The big issue will be the 2 time slots. To start, we will only support 1 
time slot. From there we should be able to expand.
The repeater will support IPSC, so it will be able to able to work on 
any of the Mototrbo networks. And maybe some others.

We think the hardware will be a RPi2 and a MMDVM Multi Mode Digital 
Voice Modem. It's in early stages but we expect it will be the best way 
to feed the VCO and tap the discriminator.
The modem consists of a Arduino Due and a small analog interface board. 
Total cost is less then $100. There is a Yahoo group for the modem.
