Their first attempt to get into the DMR market (both commercial and amateur) was the DM-5R, which while вЂњconformingвЂќ to the DMR standards had one major failure, that it was only a Tier 1 device вЂ“ that means it only transmitted on one of the two possible time slots that are available on just about every amateur repeater that is in service. Whose вЂњspectral qualityвЂќ was not always the best. While there is now a SOTA вЂњTalk GroupвЂќ (973) (this TG Died through lack of supportive use!) set up on the Brandmeister DMR network (with links from Yaesu Fusion and in the future possibly D-Star), for use as a вЂњbackchannelвЂќ between activators and between activators and chasers, and while DMR repeaters are вЂњpopping up like mushroomsвЂќ around Europe, I decided it was time to replace my old dual-band Wouxon KG-UVD1P FM HT with a DMR+FM version HT.

DMR has many, many features built into the hardware that are not used in the amateur implementations. Used both commercially and now more and more in the amateur radio world.

ДMR: Digital Mobile Radio вЂ“ Digital voice on VHF and UHF. The times are changing! with Open-GD77 firmware from Roger Clark VK3KYY, the Baofeng RD-5R / DM5R tier2 / DM-1801 / DM-860 or Radioditty GD-77/S (TYT MD-760/730) is literally transformed into a user-friendly AMATEUR Class Handie Talkie.Д«efore you consider going through all the pains and tribulations documented below to get a factory standard DMR HT to so kind of useful amateur DMR device consider ( at your own risk of course ) looking into the great work Roger and his team has done with this (still expanding) firmware upgrade. So for a long time, the advantage of buying an ICOM or Yaesu DV HT was that they were designed for amateurs to use and for this (and the smaller market), these units were (and are) more expensive. They were not primarily designed to be used as a multi-purpose radio where the user decides what the radio should do. The units would then go out into the work area and only come back when someone drove a truck over them or some other catastrophic accident happens to then. These radios were designed primarily for use by not technical people on Industrial sites, hence there may be one вЂњTechnical guyвЂќ back in the office who programs in the standard channels that they were licensed to use, but that would be all. All of what is written below is based on the DMR HT running using the firmware and concepts supplied ex-factory.
