P25-PII Control Channel Decoding Software

[TexScan780D]

Hi, I have used Unitrunker in the past on a GRE PSR-500 with a PC. I am just wondering if there a later/newer programs available out there that I might can try.

Can I run these programs from the GRE PSR-500 like I do with UniTrunker?

NO

What do I need to run these programs?

There is a beta for Unitrunker 2.0. You can find it over at Google groups.


I would use an SDR such as Airyspy R2 with any of the programs mentioned.

Isn't UT2.0 dongle only now? I don't recall... haven't used discriminator audio in ages.

I just want to decode the data channel. I have scanners to listen to voice.

An SDR paired with any of the software mentioned above will do what you're asking.

Decode it for what purpose? Might sound like a silly question, but speaking from op25's perspective, control channel decode focuses on network broadcast and group voice grant/update information elements only. If you're looking to access the data traffic or user-user call data you'd need to add more decode than is present now.

Yes, SDRs only: Realtek 820T based SDRs / Airspy / Hack RF.

I’m just interested in recording the talk-group numbers to see what I am missing.
