Hello,
I have set up a PC with LimeSDR mini, MMDVM-SDR, MMDVMHost-SDR, DMRGateway, dmrtc and qradiolink according to documentation on
I get a steady DMR noise on the control channel (checked with FM radio).
I also verified that DMR in general is working: I reconfigured my channel 7 to Trunking disabled, bypassing the dmrtc and connecting directly to the DMRGateway. The Repeater appeared in Brandmeister. With a conventional channel (Tier II) I could talk to 9990 and got a reply.
Conclusion: modulation layer seems to work well.
BUT: I programmed a Hytera PD755 A9.02.04.001 (the same I used for Tier II test above) to Trunking. DMR trunking license is active according to Feature Control in CPS.
The Hytera in Trunking mode is stuck. It just shows "Out of Range" and I have not found a way to change that.
How is Trunking working?
Is the Radio just listening for a control channel to appear and then starts transmitting to register? (I guess so!)
Or should there be any transmit activity from the radio without hearing the control channel (I guess no?)
Some Hints on the Hytrea configuration - please ask if something else is of relevance here:
Dial Rules: DMR Flat
Network Model: Tiny, NetworkID 2 (also tried 1), LA 1, LocatioN Area ID 1, Location Side ID1, System Code 00.000000001.000
TSCC Plan: Fixed Control Channel
Hunt Mode: Short Hunt
RX Base Frequence: 439.6
TX Base Frequency: 434.8
Fixed TSCC List: Channel No 5, 439.7/434.9 (that's exactly where I hear the control channel from the base station on my FM radio)
What could cause the radio not to identify the control channel and start registering?
Any ideas how to tackle this problem?
Thanks in advance for your help.
