After many attempts I finally got a red tx led and MMDVMHost showing voice frames!! .. and.... dmrtc crashed the moment voice started. Segmentation fault. Debian 11, 4gb ram, 4 cores intel x64....

Got little closer - used fixed hunt plan and base freq and shift. Now I get 'call set up' then a countdown timer, but after 5 seconds it resets, regardless of holding PTT.

Also, trying to attach a scan group (of at least 1 tg) results in segmentation fault in dmrtc. Willing to help debugging.

Okay, developer config, switched from hytera methods to self-adaptive. Now groups attach. But still can't setup call (setting up... timeout). Do I need a second radio on the net?

Radio either says 'unattached group', or (with attach off in dmrtc) it tried to set up call but times out.

Okay, my PD785 register on the system. And even able to do private calls (and get sms). But I can't get attached to any group. What settings do I use radio side? I tried everything... Log from

Well, good luck. The learning curve is pretty steep, but once you've configured everything it's smooth sailing. Keep me posted if your radios work, I'll add them to the list of supported

Great. Will test thoroughly. I got many more questions but for now I'm good haha. My testing radios are SL4000e and DP4801e.

Yes, you should be able to put in a negative split, no problem. If you can't then that's a bug in the code.

Oh, okay, I see. Thank you. I understand that dmrtc setting is for freq data broadcasted to radios. What if it's the other way around? Can I put negative value into the dmrtc (as I can - verified -

Well, in that case the split is positive, not negative in both qradiolink and dmrtc. If the radio transmits at a frequency lower than it receives, then qradiolink receives at a frequency lower than

Sorry by dvm I meant mmdvm-sdr. Can I use negative value in dmrtc if I have negative value in qradiolink? My radio's TX (mmdvm rx) needs to be below radio's RX (mmdvm tx).

RX? dmrtc will work even if the split value is wrong, but the various PDUs which contain frequency information will be wrong (absolute channel grants, frequency broadcasts etc.) Just put in the

Also.. How do I make dmrtc work when my base TX freq is higher than base RX? Right now I have, e.g. -20000000 tx split in qradiolink. E.g. dvm broadcasts cc on 440mhz, and listens on 420mhz. You

Yes, silly me, LimeSDR uses independent tx/rx paths. Great. I was able to reach CC data transmitted on air stage, pre DMRGateway and pre Controller. My question right now: if, hypothetically, I just

You can use any duplex split value as long as both frequencies are within the limits that the device supports. So you can have even 1 GHz split without any problems. The TX and RX LO are completely

Understood! Thanks for reply. One more question while I'm setting up my test lab: Limesdr-mini - what max tx/rx split can I use for T3 mode? Can it be +10mhz so I get up to 7 duplex chans at, say

It's probably possible technically, but not out of the box. Some code might need to be written for that. You'd have to ask the software authors, I don't know any specifics here

Hey all and thanks for great work. I'm wondering if I'm dreaming if I want to have LimeSDRmini with DVM-SDR in P25 trunking mode (as dvmhost does)? Thank you!

Hi Christian, Great, thanks for letting me know. I'll put your radio model in the list as supported now.
