Let me try and answer with just my viewpoint.<br><br>1: They are semi rugged and waterproof<br>2: Low cost, comes with programming lead and the software is free.<br>3: Dual band. Why in this tech-advanced age do we need to settle for a single band ?<br>4: Customising the screen using the Retevis EXXT firmware which is very similar to Travis Goodspeed&#8217;s TYT 380 toolz and provides even more options.<br>5: GPS built in<br>6: DMR and Analogue. Why not have 4 modes that you can use ? <\/p>\n\n\n\n<p>Bad points<br>1: Battery isn&#8217;t really an all day one, especially when you are on analogue. DMR does reduce the power consumption I&#8217;ve noticed.<br>2: No vehicle dock to charge or use the radio. Surely it&#8217;s quite an easy thing to do ?<br>3: Programming can be awkward for non-computer people, as can the software and having to program the zones, channels and contacts. (but there are ways&#8230;)<\/p>\n\n\n\n<p>I&#8217;m sure that some people will say that DMR should remain a commercial mode, doesn&#8217;t have a place in the amateur world, but it&#8217;s here, there are plenty of worldwide users, plus it&#8217;s open source so anyone can work to improve it. Provided you have the coding and electronics knowledge of course.<\/p>\n\n\n\n<p>I use daily one in the car, with a speaker mic, a battery eliminator and a window mount antenna, with a Nagoya flexible whip, which comes down nightly.<br>Coverage isn&#8217;t bad, people say the audio is good, and I&#8217;ve had some crystal clear DMR to DMR conversations on the move, although when I moved repeaters it threw up an error that I was unaware of.<\/p>\n\n\n\n<p><strong>The error.<\/strong><br>When I had the initial codeplug loaded, everything worked perfectly. Sure there were a few things missing, to be updated and tested.<br>What I didn&#8217;t know until I spoke to another amateur, <em>was that non-Motorola DMR has an issue with deleting a channel<\/em>, so that it messes up the rest of the channels, only slightly, so that you may think you&#8217;re speaking on say, talkgroup 9, but you&#8217;re on a completely different talkgroup, or even timeslot.<br>I can only speak as to what I found in this instance, sadly I don&#8217;t have any Motorola kit to test this theory on.<br><strong>The Fix<\/strong><br>I reloaded the full codeplug and this seemed to have solved the issue. It&#8217;s almost impossible for me to test every UK DMR repeater at this time, so I can only go on the few that I&#8217;ve managed to reach thus far.<br><br><\/p>\n","protected":false},"excerpt":{"rendered":"<p>After discovering they were the same as the RT82 and MD2017 and having to take one apart to fix a faulty screen issue, I&#8217;m loving these handheld radios !Why ?Good question.
