My employer has some frequencies from 406 to 420 mHz that we use with MOTO TRBO equipment. We also need interoperability with our "local" neighbors who use 800 mHz on a digital, trunked system. While we get by now with two separate radios, it might be nice to have one radio for everything. Anyway, does Motorola, or anybody else for that matter, make a radio that will work on 400 mHz MOTO TRBO AND 800 mHz APCO P25 digital trunking? I assume that the answer is still no, but I hope that might change in the hear future.
Think merging a 400 mHz MOTOTRBO XPR 6550 with an 800 mHz XTS 5000, if you will. It looks like a Motorola APX 7000 will NOT do MOTO TRBO, at least just yet.

Nope, no one at this point, and I suspect Moto won't introduce TRBO in the APX since they want to push public safety to Astro25 and push business/commercial to TRBO.
Depending on how many units you want to buy, I would consider having a talk with Harris and/or Thales.

This is straight from the motorola XPR4380 service manual. Funny they mention APCO C4FM in a XPR.
"800/900 MHz (851–870, 935–941MHz) Band Receiver Circuitry
The receiver is dual-band operating in both the 800 MHz and 900 MHz bands capable of FM, 4-level
FSK and APCO C4FM demodulation. It is a dual-conversion super-heterodyne using IF frequencies
73.35 and 2.25 MHz. This configuration allows for a dynamic range of 130 dB in both analog and
digital modes. The receiver in general is divided into three sections, front-end, back-end, and DSP.
The overall block diagram is shown below in Figure 1-1."

Build a gateway, and make the 800 system a talkgroup on the Trbo. It would be D_A_D, but it might sound okay.
