Hello John, Today, "rolling your own" pretty much means a "stand-alone" repeater (FM discriminator to modulator, optionally decoding the GMSK and doing bit-regeneration and GMSK out).
The RP2000V talks to the RP2C using an Icom specific protocol, AA4RC ([email protected]) knows the details if you wanted to attempt building a circuit to take the GMSK encoded/decoded to/from modified radios and connect it to the controller (it's all digital). Or you might be able to build your own controller to talk to the gateway using Icom's protocol. All of this is a lot to accomplish and you would have to look at your group's expertise. On the other hand, there are projects by Satoshi Yasuda 7M3TJZ (see: http://kb9mwr.blogspot.com/2009/01/satoshi-7m3tjzs-d-star-node-and-dv.html) and Fred N. van Kempen, PA4YBR/KA4YBR that will provide much of the hardware to get from the radio to a bit stream and back and when combined with an open source gateway (ala http://www.opendstar.org/design/) provides a way to get there (probably at least 12 months out). The D-STAR International Coordinating Council will be a channel to get access to a testbed for "home grown" D-STAR software and hardware (working against a Trust Server and verifying compatibility). Bottom line, you can "roll your own" standalone, or using a number of projects underway get to something some months out that will be able to talk to the D-STAR network. Time vs. resources is the deciding factor. I hope my short statement to Vicky didn't mislead.
