The other method to communicate with a radio is through a repeater. A repeater is an electronic device that receives a signal on one frequency and retransmits it at a higher level or higher power, or onto the other side of an obstruction on a different frequency, so that the signal can cover longer distances. So, the repeater’s transmitting frequency is our receiving frequency and our transmitting frequency is the repeater’s receiving frequency.

For business & private radio, DMR followed by NXDN is the two most popular choice. For emergency services and government communications, P25 is by far the most dominant, there’s no doubt about that. And guess what? Absolutely none of them are compatible!Choosing what digital voice standard you'll go with can be daunting.With Tier 2 DMR, repeaters are used in a TDMA arrangement, with two "timeslots. The human voice is digitally sampled and compressed with the AMBE+2 codec, and then transmitted in this digital form to another radio.Tier 2: Things start to get a bit more complicated here. This is helped in no small part by the ready availability of DMR radio equipment at prices that rival traditional analog two-way radio, and that one of the biggest names in two-way radio, Motorola, are throwing their weight behind DMR.Motorola's SL7750 blurs the line between DMR radio and cellular mobile phoneThere are three "tiers" or levels of functionality for DMR systems.Tier 1: The simplest form of DMR is Tier 1, which is mainly used for simplex communications, with no repeaters. Hams have always been keen to leverage off existing commercial equipment, and it seems the most popular commercial system adopted presently is DMR.Personally, I think DMR will take the lead in both the commercial business & private two-way radio field as well as in ham radio. Pro cycling manager 2004 demo downloadThis is used by more complex or larger networks for big businesses and commercial radio users.So why go to all this trouble, when plain old analogue FM works perfectly well? DMR has the advantage that it four times more efficient when it comes to spectrum usage. A pool of frequencies are used to carry the TDMA transmissions. All amateur radio DMR systems are Tier 2, as are many business / commercial radio DMR systems.Tier 3: This is effectively a trunked radio system on top of Tier 2. Again, the AMBE+2 codec is used to turn speech into compressed data for transmission. Repeaters can be linked via the internet to form networks that can be as small as just two repeaters, or thousands of repeaters across the world. In addition to this, radios can be set to logical closed groups called ’talk groups’, which you can think of as ’virtual channels’. DMR is also designed to be easy to network, with connections using IP, so creating wide coverage areas using a network of DMR repeaters is already built-in cover your city or cover the entire country! Yet another advantage is because a DMR transmitter is only turned on about half the time due to it transmitting in bursts, battery life is longer.TYT's hugely popular MD-380 can be bought for around $100Colour codes: Every DMR transmission uses a "colour code" which is very similar to CTCSS or PL tones in the analogue radio world. While not every DMR network supports it, sending of data and short messages is also possible. Not only that, but DMR offers some very flexible calling facilities - you can call one person, a group of people, or everyone in your fleet at once. ZUMspot, Jumbospot, Openspot, MMDVM etc are all examples of hotspots that you can buy or build yourself.Radioddity GD-77, dual band, DMR & FM, I think the best bang-for-your-buck DMR portable, also around $100The use of DMR in radio hobbyist circles falls into two categories: ham / amateur radio and scanning receiver use. Most hotspots are multi-mode, handling not only DMR but DStar, Yaesu Fusion and P25 as well. You can even take them with you and use your cell / mobile phone wireless data to connect the hotspot to the internet and be able to use DMR anywhere you get cellular signal. Simply put, this is the software you’d use to create a "code plug" and configure your radio.Hotspot: A small box that connects to the internet and acts like your own personal low power DMR repeater, useful if you're not in range of a DMR repeater to access. The code plug can be saved to computer disc, and is used to program a radio to give it the functionality a user requires.CPS: Another Motorola term, meaning Customer Program Software. In some cases, you can get on air to the DMR scene for less than a hundred dollars!Scanning: As the world relentlessly marches on to a digital future, many businesses and commercial interests have migrated their legacy analogue FM two way radio systems to DMR. Motorola DMR equipment is frequently used, but increasingly the cheaper units, in particular TYT, have increased the affordability and availability of DMR equipment to the mass market. Depending on the talk group selected, you could be communicating just around town, across your region, across the entire country, and some groups even cover the world. Worldwide, DMR enabled and connected repeaters are appearing and are interconnected to provide a huge linked network spanning the entire globe. Wwwhgstcomtech supportfor instructions on re format for macFor those hobbyists who can’t justify the high price tag of those scanners to listen in to DMR, there are other alternatives: certain computer software can decode DMR with a regular scanner and a ’discriminator tap’, or a ’virtual audio cable’ if using an SDR, or if portable DMR reception is desired, an entry level DMR transceiver from TYT or Radioddity will do the job very well - to keep yourself on the correct side of the law, you should disable any transmit capabilities of these transceivers.
