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. <https://groups.yahoo.com/neo/groups/mmdvm/info> 73, Steve N4IRS On 11/25/2015 06:59 PM, Buddy Brannan wrote:
We have no digital nothin' in Erie. No DSTAR, no DMR, none of that. Will this be the thing that pushes me over the edge? Especially if I can do something or other without buying a whole Motorola repeater?

Jeff, That's great to hear, We will want to test two way traffic on a larger scale. The RPi2 it's running on is not even breathing heavy. I'll post when we are ready to start testing two way.

Wow Steve! That's cool! I've been very interested in something like this. We normally bridge via a remote base. We have a statewide dmr network that I could help test it on. I'm a stakeholder so we can run two way traffic with no restrictions.

N4IRR and N4IRS (INAD) would like to announce the first in a series of digital <---> analog Gateways. As a proof of concept, Virtual Hub Node 2100 is hosting the DMR-MARC to Allstar Gateway. This is a receive only Gateway bridging DMR-MARC. DCI and DMR+ to AllStar. This proof of concept is using no Motorola software or hardware.
This is running on a Raspberry Pi2
Later versions of the Gateway will allow 2 way communications with Digital networks.
