09 Control Head with Dual APX Remote Radio Configuration

Post by rpowell911 »

Hey, guys.

Had an 07 xontrol head, with the Motorola dual-radio (two single-band APX 6500's, VHF & 700/800) setup in my previous vehicle. 2015 Tahoe PPV.

Worked great.

New (2016) truck has 09 Control Head, with dual-band single-deck (700/800 & VHF) APX 7500. Only flaw is no priority on scan when in Multi-System Talkgroup scan list (both VHF and Trunking scan list, simultaneously).

I can live with that, but, I can't for the life of me understand why Motorola does NOT allow the dual-radio setup with the 09 control head, when they do provide that functionality with the 07 control head. I mean, why have a $650.00 control head do stuff that a $1600.00 control head will not do?

Anybody know of a workaround, hack, or date when Motorola might offer the firmware so that the 09 control head will operate in dual-radio mode with two compatible APX radios containing the proper firmware? (I actually tried this with my old two-APX setup. Got the error code of "CH Not Supported" or somesuch.

Thanks for any help you guys can provide.

Dual radio was supposedly coming to the O9 head, but with the imminent release of the 8500 mobile I doubt we'll see it now.

Multi-system scan is incapable of priority because of how it's handled on trunking systems - with embedded data in the voice channel stream (or subaudible data on a 3600 analog system) versus "lookback" to the priority channel in conventional. Many sysadmins discourage or don't allow multi-system trunking scan due to the likelihood of missing traffic.
