btw, only in NEO there is no audio output, but if I test the same file in FME it works fine.

A little off topic, but does anyone have a collection of raw discriminator recordings of the digital modes? (DMR, Fusion, D-Star, M17)... I'd like to do some comparisons with these and dsd-neo. Thanks

ki4hyf · Thursday at 4:22 PM

Will this help? DMR Samples
I've got a few others, but it's mainly DMR and P25. There is very little in the way of exotic ham modes in my area. All of the samples I have are either .bin or .wav files.

One mode is a start I guess.

gary123 · Friday at 12:52 PM

I see that arancoremonk made his samples at 9600 and Melerix made his at 4800. I think NEO likes the 9600 more than the slower 4800. I do not know if this is part of the no decode problem?

I am not sure if there is a setting in NEO to show the AMBE frame data. Having this information would go a long way to figuring out why its not decoding the audio properly. I do not know if NEO has a BP lookup or if its processing the frame with the wrong key data. Seeing the actual frame bytes would clear this up.

If NEO does not output the AMBE frame data this would be an excellent option to add to future releases. Also on the wish list would be to directly show the MFID,KID and ALGID. Perhaps a new switch in the command line that enables the display of this information?

If that's Motorola BP, then how come that sample doesn't have service option bits indicating its encrypted.

gary123 · Friday at 3:00 PM

Moto BP does not set them for BP. I think it was deliberate so that other users knew it was encrypted.

no idea, but it works fine in FME, only in NEO is not decoding properly.

lwvmobile · Friday at 3:16 PM

Yeah, I don't think so. Its not a Motorola radio doing that. The MFID isn't set to 0x10 either, and the SVC options aren't set to encrypted in the link control. That's probably a Baofeng or some CCR using a custom privacy key that is the same keystream as Motorola bp key 100, in other words, probably set to -S 49:45024562456245 or something in their CPS.

Thanks for the capture and the extra detail. I was able to reproduce the behavior. The issue was in DSD-neo’s live audio output path, not the WAV sample rate or the privacy decode itself. File playback was decoding faster than real time into the async audio output queue, and that queue is designed to drop older samples when it overruns. That made the played audio sound extremely sped up/choppy even though the decoded WAV output duration was correct.

I’ve changed finite inputs like WAV/stdin/symbol replays to use blocking audio output so playback is paced properly, while keeping the low-latency async path for live/radio inputs. I also cleaned up the misleading DMR direct-mode slot display and the extra state-machine log spam seen in the report. The latest nightly build will include the fix once it's finished compiling.

Yeah, I don't think so. Its not a Motorola radio doing that. The MFID isn't set to 0x10 either, and the SVC options aren't set to encrypted in the link control. That's probably a Baofeng or some CCR using a custom privacy key that is the same keystream as Motorola bp key 100, in other words, probably set to -S 49:45024562456245 or something in their CPS.

Agreed. Looking a bit more closely, it has all the characteristics of Tytera Enhanced Privacy (or something very similar, likelihood it's badged as something different). I recall seeing some reports of folks being able to make a Moto BP interoperate one-way with a Tytera EP presumably with a subset of keys that would generate sufficiently similar keystreams
