Decoding Motorola TPS Unit IDs

[KC2YSI]

Does anyone know of software that can decode Motorola TPS Unit IDs? I know they are ASTRO25 IDs transmitted over conventional analog channels, but nothing I have tried seems to work so far. There is an example audio file in the following forum post: http://forums.radioreference.com/motorola-forum/115350-motorola-chirping.html

MDCTool is one way I believe,But not sure if it will decode in live time or from recording.

Been working on getting MDCtool up but hit a wall..I think it may take VirtualCable.

I'll check out MDCTool, but these are ASTRO25 tones, not MDC1200 tones.

Unfortunately, MDCTool did not work, even with a clean MDC recording and live audio.

Those are ASTRO25 TSBK's and have nothing to do with MDC.

I don't think anybody has ever come up with a decoding solution for hobbiests yet. I'm not even sure how widespread the use of TPS is.

Thank you Mike, I know it isn't MDC-1200. I'll research some more on ASTRO25 TSBK.

Run DSD or DSD+ on this.

If these are standard P25 voice channel Link Control messages (some of which include unit IDs), then DSD / DSD+ should tell you something.
