If you intend on [[Using DMR]] you can register with the DMR-MARC Worldwide Network, which will allow you access to the many DMR repeaters available worldwide. DMR-MARC is for MotoTRBO radios as well as compatible DMR clones including the [[Tytera MD-380]].Motorola digital radio. Compatible with the European 2-slot DMR standard and uses Time Division Multiple Access (TDMA). MOTOTRBO has a few more features than a standard DMR radio including IP Site Connect. Motorola maintains two-slot 12.5 kHz TDMA-based systems, providing 6.25 kHz equivalency.Motorola digital radio.

It has a feature missing from many of the other digital modes in the repeater, and that is the ability to operate in mixed mode digital and analog. Fusion makes it possible for you to send digital pictures if your fusion radio has a camera.All System Fusion radios, (FTM-400DR mobile, FT1D and FT2D) radios can operate in fixed FM mode, DN (Digital Narrow @ 6.25 KHz ) or VW (Voice Wide 12.5 KHz signal).Questions: 1) Did fusion come from the Part 90 world like DMR/MotoTRBO, or was it developed for ham radio like D-Star?2) Does fusion support data roaming like D-Star and MotoTRBO?3) Talk groups and IP packet support?===C4FM FDMA===System Fusion C4FM by Yaesu is the current implementation of Yaesu's digital radio for ham. The 12.5 kHz channel spacing in using the C4FM FDMA digital modulation mode allows high-speed data communication, voice communication and error correction. The data transfer speed is 9.6 kbps.
