What the heck is this Trbo radio?

[Cheezhead]

Its in a XPR4550 chassis it has a BNC antenna connector on it. I cant read it with any CPS.

That looks interesting - the extra SMA connector in the middle of the PCB intrigues me. The MC Micro line (made in Germany) had BNC connectors so it's probably a European or Canadian motorcycle radio, or maybe the extra SMA connector is for some kind of full-duplex or repeater set-up, perhaps? Or, maybe it's an escapee from some engineering lab. The region code is AS - is that Australia or Asia?

Accordingly to region and band it's Asian animal. Usual TRBO Gen. 1 mobile radio with built-in GPS.

The SMA connector isn't connected to anything other than soldered to the ground trace the center lead isn't connected.

Friend of mine has one of these as well, except his came with NA 'D' (development) series firmware in it.

 

[MotFAN]

These firmware is 'T' version. I belive that it's also some kind of Test/Development FW.

All european TRBO mobiles (Model designation DM XXXX) has BNC connectors. The SMA sticking out from the PCB is surely a testing add-on

 

[duggerd]

The SMA connector bodged on there is most likely for a conducted emissions regulatory test. The development firmware makes sense there too. In the US it would be for the FCC, but I do not know what the equivalent for Asia is.

350-400MHz. Nice. What software is the OP using to view the version numbers in that photo?

 

[Cheezhead]

I guess that question didn't need to be asked.

 

[MotFAN]

But I want to know it too. Never seen this software.
