Hello Guys, i'm using the Last Version of DSD+ Fast Lane and SDR Uno for scanning 5 frequencies. All DMR TIII but i can't listening audio on this frequencies.

If anyone can help and explain for me how this frequencies work, i will thank you.

Under the List Frequencies and infos about them.

-468.075 = TIII (MOT) Site:S1-16 DCC:0 RAS NL:14 15
Private Data Call: Tgt=40100 Src=1165 Ch=56
Private Data Call: Tgt=40100 Src=1205 Ch=55
Group Call: TG=179 RID=1213 Ch=56
ACK: WAIT Tgt=1164 Src=40100
ACK: REG/DEREG ACCEPT Tgt=1187 Src=REGI

================================================================

-468.100 = TIII (XXX) Site:S1-15 DCC:0 RAS
Enc Group Call TG=171 RID=895 Slot=2 Alg=EP/RC4 KeyID=5

================================================================

-468.225 = TIII (XXX) Site:S1-14 DCC:0 RAS
Enc Group Call TG=170 RID=860 Slot=2 Alg=EP/RC4 KeyID=5

================================================================

-468.325 = TIII (XXX) Site:S1-16 DCC:0 RAS
Enc Group Call TG=179 RID=1209 Ch=55 Alg=EP/RC4 KeyID=5
Enc Group Call TG=179 RID=1209 Ch=56 Alg=EP/RC4 KeyID=5
Private Data Call: Tgt=40100 Src=1165 Ch=56
Private Data Call: Tgt=40100 Src=1187 Ch=55

================================================================

-468.350 = TIII (MOT) Site:S1-15 DCC:0 RAS NL:14 16
Private Data Call: Tgt=40100 Src=1264 Ch=20

Some of what you posted is showing encrypted but some also show as group call . Do you know if those comms are in the clear? How is your signal and ppm?

I can't listening all the calls same the don't encrypted.
The signal is HIGH and ppm is 0,5.

All the Frequencies are "TIII (MOT)" what is it? and "Site:S1-15 DCC:0 RAS NL:14 16"?

Can you explain what is "ACK: REG/DEREG ACCEPT Tgt=1187 Src=REGI" and "Alg=EP/RC4 KeyID=5" for example.

They do encrypt. It's clearly shown. You aren't going to be able to listen to encrypted communications.

And if you are listening to TIII DMR Sites, you can't just sit on the control channel with SDRUno and expect to hear voice. You need to tune to the voice channels (frequencies).

But good luck, they are encrypted.

Yes, it's a trunking site. I have no idea how you are going to find the frequencies other than to watch when a voice call occurs while monitoring the control channel, and then search the band for a corresponding frequency that is transmitting the voice content.

Then again, all information you have shown suggests that they are encrypted.

You wouldn't if you actually used FMP24 (dongle) / FMPA (airspy) / FMPP (rsp) + DSDplus together instead of SDRUno. But, you would (a) have to know the frequencies in use and (b) have to know the LCNs associated with each of those frequencies that are part of the site.

I won't be answering any more questions.
