Versions of DSD+ that auto-decrypt MotoTRBO basic/enhanced privacy and P25 ADP have been created, but there are no plans to release these. They would only increase the use of real encryption. The team debated whether LRRP (GPS) functionality should be released as some public safety systems use it, but those agencies have the option of encrypting their data, and should be, so LRRP is ok. Same thing for text messaging.

Love DSD+. Can't wait to see this new release!

Will this new version decode voice and show GPS position from D-STAR network? Some good news on NXDN data decoding?
No D-Star enhancements yet.

Also, I don't see the radio numbers of a radio-to-radio individual call in the output like I can for a group call. Is that a program limitation, or does this information not exist on the voice channel?

I would pay $$ for this feature as it would simplify recording a lot (no need to send the audio to a separate program using another virtual audio cable), and even possible (Unitrunker does not show individual calls being active the full time that DSD+ shows audio data coming in, and if you record based on that you only get bits and pieces of a call)
You should upload raw audio samples of unit to unit calls.

PM me to arrange any paid features.

Team members should not reveal themselves. If it's fakery, it's elaborate. Zippyshare.com - LRRP.avi

Here's a sample unit to unit call. Note that I don't know what the unit numbers are; I can try to do another one and note what they are on it if needed.

DSDplus - thank you for the update. To clarify re my last, the intention was not to reveal beta testers - but just to see if there was actually any progress being made as it had been a while since your last update: your latest series of postings is really welcome.

Any progress on NXDN decoding (RAN, GID, UID) is a big bonus, so really welcome that too.

Also, like rosecitytransit, starting new recording file for each call would be a nice feature if that could be added.

If you need any help with any combination of conventional DMR/NXDN samples I can help out here.

Question Pro-107 DSD+

My local leo uses mototrbo analog, all I get is motorboating, can I download a program to my scanner for this? Was recently told that they went digital but my analog scanner stops on the frequency when they transmit, just motorboat.

Hi DSDplus

First, really thanks for the development of this great program.
Second, the new version of the program will decode dPMR tier 1 or 2??

Thanks a lot

Hi,

Thank you for your work! Can't wait to try this new version of DSD+!

Do NXDN Control Channel informations decoding (Channels grant, System/Site ID, Neighbors) and Nexedge Over-The-Air Alias are part of the new release?

Thank you again!

There is no such thing as 'MotoTRBO analog'. Its either analog or its MotoTRBO... And no, there isn't anything you can download to a scanner. The motorboat you are hearing on you analog radio is the TDMA digital.

We need clean samples of dPMR transmissions and detailed codec information.

It is being worked on, but more audio samples would help.

I can help with that. I'll upload some records and will give you link to download. There are two NXDN systems here. One on VHF band and one on UHF. I'll give you some records on both of them.

Done. I've uploaded some samples. You can find from here:

https://dl.dropboxusercontent.com/u/...3%40171419.wav

https://dl.dropboxusercontent.com/u/...3%40171654.wav

https://dl.dropboxusercontent.com/u/...3%40170709.wav

https://dl.dropboxusercontent.com/u/...3%40170909.wav

As you can see these are VHF voice and data and UHF voice and data.
On VHF band each service has it's own frequency so there is no frequency hopping to follow the conversations. There are several control channels that change their frequency over 24h period.
On UHF band, control channels are static but there is a frecuency hopping so if you want to follow the conversation you must be able to "read" the control channel.
Every conversation, on both UHF and VHF band start with 2 frames of data and everything else is voice. Sometimes during long voice reports there is 2 data frames somewhere in the middle and sometimes 1 or 2 at the end.
Well, basically this is what I'm getting here. If you need some more information that I can provide to you, feel free to contact me

Ill bump that!

Thanks a million to all the programmers and beta testers,as well as the folks contributing samples from local systems to the team so they can create a broad working application.

We know you do this because you love it,and offering it to us is very much appreciated!

2 Individual Call 2 2 GHIJKL 1 ABCDEF 1 NXDN9600 Conventional
3 Individual Call 3 3 xyz 65519 Test 1 NXDN9600 Conventional
4 Individual Call 65519 65519 Test 3 xyz 1 NXDN9600 Conventional
5 Group Call 65519 65519 Test GROUP ID 1 1 NXDN9600 Conventional
