DSDPlus Trouble Decoding DMR TIII on DSDPlus Fast Lane – Need Help

[sscg]

Hey everyone,

I wish you all the best!

I aimed to contact you because I was having a lot of trouble decoding Hytera DMR TIII audio with DSDPlus Fast Lane. I've tried a few request steps and still can't seem to fix the problem. Here's a detailed breakdown of what I've done so far:

1. 设置：我按照说明将DSDPlusDLLs 文件和 FjqhaapHi9_DSDPlus2p465 文件放入DSDPlus1p101文件夹中。
2. Running the software: I first open the FMP24.exe and then run the 1R.bat. I'm using a single RTL-SDR.
3. The version SDPlus is up to date.
4. Audio Output: To verify the audio settings, the setting I entered was "Always monitor source audio". My headphones made a sound, confirming that if the audio was decoded, I would hear it. After verifying, I switched back to setting "Passive Audio Monitoring".
5. Observation: During decoding, when DSDPlus detects voice communication, my headphones make a noise or two, which may be a signal when the PTT key is released, but I'm not sure.
6. Signal quality: I contacted the U-band base station on the roof, so the signal quality is very good. My computer is running Windows 10 64-bit.
7. Location: I receive a signal outside the United States.

Despite following these steps and doing extensive online research, I still can't decode the audio. I guess is there anyone else who has had a similar issue with the Hytera DMR TIII signal on the DSDPlus Fast Lane? If that's the case, how did you fix it?

We propose or direct in my honor. With the help of Nian Nian in advance, I wish you all a great day!

It appears that you are not on the control channel for the system. In the Channel Activity window, you should see Channel info and not Slot info (S1/S2). It would also Tell you System ID and Site when you get the Control Channel.
Try some of the other similar spikes in the FMP24 window

Also, you want your bandwidth in FMP24 to be 7.6 for DMR. (shortcut is "b" key).

hanks a ton for your response and the helpful tips!
I’ll definitely check if I’m on the control channel by looking for Channel info instead of Slot info (S1/S2) in the Channel Activity . I’ll also look out for the System ID and Site information to confirm I’ve got the Control Channel.
I’ll try tuning into some of the other similar spikes in the FMP24 window, as you suggested.

Thanks again for your help! I really appreciate it.
