There are other issues, the AMBE+2 codec used 4 is proprietary and costs an arm and a leg to license, we locked ourselves in to DVSI’s proprietary codec and would now have to throw our rigs away and buy new to change that. It is not done well but you are surprised to find it done at all. is like a dog’s walking on his hind legs. It is remarkable that this is intelligible at all, in the words of Samuel Johnson: This is due to the AMBE+2 speech codec and the 2450b/s digital capacity of a single channel 3. Use the parrot function on the repeater to hear what you sound like. It’s better if you close-talk the rig and get enough volume. DMR is never going to sound greatĭV sounds horrible and robotic. I am the odd one out in the club using a Retevis RT84, so I cannot use the Anytone codeplug. It’s obvious in hindsight, but took a lot of messing about to get there, and thanks to G5FM and 2E0OSS for some late night experimentation on FI to shake down what was going on. I wanted to understand what the codeplug did and how to get control of my own radio so it does what I want it to do, and to set it so that I know what I am doing. That’s great for chatty types and a real boon for mobile operators, but I am on the geek end of the spectrum, and my fight was trying to make sure that I stay on the GB7FI repeater and don’t get drifted off to a UK or world-wide talkgroup. It’s all too easy on DMR to end up accidentally talking to the whole world or the UK in general. That’s kind of bad in a handheld ) The aim of this piece is to outline the stages in getting to use GB7FI for local talkback when we are experimenting with datamodes.

DMR on the other-hand often isn’t quite so user friendly, requiring some research and understanding of the mode. With most analogue (FM) radios they are ready to go straight out of the box. Most of the issue with DV is summarised in this paragraph of analogue vs DMR That makes DMR rigs a real bear to set up, and many people rely on codeplugs 2 set up by others.Ī good guide to DMR is on. DMR is based on business radio, and inherits a lot of complexity from business users requirements. It’s quite a neat rig, with GPS, APRS, FM voice and DMR at a reasonable price point for the functionality, compared to say the Yaesu FT-3DE at a higher price point (and the C4FM Fusion digital voice, which does not interwork 1 with DMR). Many members of the club have the Anytone AT878UV DMR/analogue handheld. monitoring yourself, the repeater or another user.Usage - selecting a talkgroup on the repeater.Repeater Slot: Otherwise known as Time Slot.creating a Digital Contact for local TG 9.Setting up DMR for simplex and use on the GB7FI Phoenix-UK repeater
