DSD FME

[EI9BAB]

What version are you using? The filename was re-written a good while back. The special character is a : and at the time, I didn't know you couldn't use those in filenames in Windows (Linux didn't care) but its using the 20250814_112037_19839_EDACS_SITE_001_Digital_Group_Voice_Call__TGT_628_AFS_04_144_SRC_LID_UNK now.

Thanks for the explanation. I was using the latest updated CYGWIN version but I was using the original DSD-FME instead of the AERO version which is newer. I am using that now and the filename is sorted. Thanks for your help!

Anybody who would consider themselves knowledgeable or power users of DSD-FME, and have an RTL dongle, we are seeking feedback on a new branch of code that overhauls the RTL input and from our limited testing. You'll need to be able to compile the source code yourself from the rtl_overhaul branch and test out with limited or zero hand holding. Initial testing shows much better reception with a variety of systems, but we can't test every edge case, so testing and feedback on your local systems would be most appreciated.

More information can be found here.

@lwvmobile are you adding new encryption systems? I have a DMR radio whose encryption is not yet supported by dsd-fme. If so, how can i send you the capture files because they are too big to put them here.

And which kind would that be? If you want to submit samples, upload them to a file host of some sort and paste the link in the forum here.

I would like to send you the samples and information in private message, but I am not allowed to send private messages.
Maybe if you write to me privately I can answer?

I play a DMR baseband file but dsd-fme doesn't decode anything, what should I do? This works fine with a normal wav file.

The picture shows that it's missing P25 Phase2 parameters. You need to add them to your command line, like:-X BEE00123456. Where the BEE00123 is your system and 456 is the NAC. It should decode okay then.

No no, it's not phase 2 of the P25, it's the DMR. I used dsd-fme -Z for auto-detection, with a normal wav file it works fine but with a baseband file it doesn't display anything or shows a tiny bit of incorrect P25 frame.

Just out of curiosity, what is the source of the baseband file in question?

How is the audio routed? If you are to do something like this, you typically need some VC-cable to route audio from SDR# to DSD-FME. Also, since its SDR#, you'll need to hunt down and disable the multitude of audio processing like high pass, low pass, de-emph, and whatever else if you are using the community version with the 1000 mods on it.
