So here it is, a FT-1DR:
Their PDF talked a lot about C4FM. So many hoped they'd use IMBE and let it work with P25 gear.
They also talked about DMR (compatible with MotoTRBO), and we know the Vertex Standard branch does have DMR radios like the VXD-720 DMR HT.
However, there are 3 tiers in the DMR standard (described in ETSI technical standard TS102 361):
DMR Tier I products are for license-free use in the 446MHz band.
Under Tier I, ETSI has also defined two Tier-1 protocols:
DMR Tier-1 protocol utilizes 12.5kHz FDMA <---- br=""> dPMR protocol utilizes 6.25kHz FDMA
Both protocols provide for consumer applications and low-power commercial applications, using a maximum of 0.5 watt RF power. With a limited number of channels and no use of repeaters, no use of telephone interconnects, and fixed/integrated antennas, Tier-1 DMR/dPMR devices are best suited for personal use, recreation, small retail and other settings that don’t require wide area coverage and advanced features.
DMR Tier II covers hand portables, mobiles and base stations operating in the VHF and UHF allocations for PMR.
The ETSI DMR Tier-2 standard is targeted to those users who need spectral efficiency, advanced voice features and integrated IP data services in licensed bands for high-power communications. ETSI DMR Tier-2 calls for two slot TDMA in 12.5 kHz channels.
DMR Tier III products will support trunking operation.---->
Most savvy hams are familiar with Tier-2. This is what the above mentioned Vertex/Standard VXD-720 uses, as well as MotoTRBO.
According to a Yeasu FT1D sales flier picked up at Dayton :
C4FM 12.5 KHz FDMA.
Peak data transfer rate 9.6 kbps.
It can send a 320x240 pixel picture using a camera speaker mic. (as eluded to on the universal radio page)
It takes 20 seconds to send the picture over the air at 320x240, and 4 seconds at 160x120.
Because of display limitations, it can only save it in JPEG format to the Micro SD card slot on the camera. It can't display it on the radio itself.
What is interesting is the radio has a USB connector. This is for accessing the camera speaker mic as a webcam, and for firmware updates.
So in effect it's not really compatible with anything other than the cheesy radios designed for the license free PMR 446 band in Europe. But never fear, keep your anticipating eyes open for the Yaesu radio that will be compatible with Tier-2 DMR:

At this point in time, Vertex Standard believes the C4FM (4-level FSK) FDMA or TDMA are the most suitable selections for Amateur radio applications. In early 2012, we will release a C4FM (4-level FSK) FDMA Handy-Talky and a Mobile transceiver into the Amateur radio market.
After our initial introduction, we plan to introduce a C4FM (4-level FSK) TDMA (2 slots) or TDMA Handy and Mobile transceiver into the Amateur market.
