Hi All; After months of development / testing and challenges with my repeater site <G>, we now have two fully functional / automatic D-STAR compatible and FM (app_rpt enabled) repeaters on-the-air in the Greater Toronto Area. The repeaters both use commercial grade FM repeaters. The auto-switching between FM and DV is managed by an external multiplexer that Jon (VA3RQ) and I designed. In the case of repeaters that have two audio inputs (TXA and TD), the multiplexer allows for the switching of audio between these 2 inputs (FM audio into the TXA input and D-STAR 'data' into the TD input). For repeaters that have only one audio input, the Multiplexer caters for this case too. Please contact me off-list for further details. Just for the record, we are not selling the Multiplexer, it is an open source project, the schematic is available, you build it, you get to enjoy it :). Cheers! Ramesh.
