I am using a 2 dongle setup in Unitrunker. Local government in Harrisonburg-Rockingham County VA uses an 800mhz EDACS ProVoice system. The vast majority of the traffic on the system is digital. Unitrunker output is being routed to DSDplus for decoding which is working flawlessly for digital traffic. The first attached screenshot with a ProVoice label in the filename shows the receiver configurations, site information, and DSDplus scope for digital traffic that is being processed correctly.
My issue is that two of the primary fire-rescue dispatch channels are analog and when these channels are being tuned by Unitrunker there is no audio output to the PC speaker. I can validate that the traffic is analog in two ways. I have a Harris XP-25 handheld unit that reflects an analog indicator when there is traffic on the dispatch channels. In addition, if I direct the digital output to the PC speaker the traffic on the dispatch channels comes through loud and clear while the digital channels produce "noise" since it is not running through the decoder.
In summary, in the working digital decoded voice setup, Unitrunker is identifying the analog traffic as digital and therefore the analog signal is being passed to DSDplus. DSDplus is obviously not looking for analog traffic and therefore ignores this input. You can see this in the second screenshot I have attached where the "RFR Tac 1 Dispatch" talk group is active and being tuned by the voice receiver. Note that the "SVC" field reflects "Dig". In addition, the screenshot was taken during an audio tone and you can see the tone being generated on the DSDplus scope. Again, this analog signal is being passed through the digital output by Unitrunker and therefore no audio is being generated to the PC speaker.
I have worked on adjustments to the receiver configurations but it seems like the underlying issue is "misidentification" of the analog traffic by Unitrunker. Any assistance on what may be causing this to occur would be greatly appreciated.
Thanks,
Daryl
