Someone please correct me if I'm wrong. From the reading I've done about DMR, it's not possible to do HT to HT simplex because a repeater is required to synchronize the time slots. Also, do DMR HT radios support those obsolete FM repeaters with CTCSS tones? I've gone through the manual for a couple of Motorola HTs and I don't see how they are programmed.
I'll come out of the closet and admit that I'm becoming a D-STAR fan boy. I've done a lot of research on Fusion, DMR and D-STAR and believe that D-STAR currently offers the best combination of features. Fusion may get there, but I'm just not getting DMR. |

Most TRBO/DMR radios will do anything analog that any other radio will do (there are a couple of Motorola portables that are digital only), So, you can use analog repeaters with PL tones. As far as simplex in digital mode, they will do that to. The radios can handle syncing the digital frames between themselves for simplex. I use a XPR 4550 and 7550 on analog and digital on a regular basis. And just to add my .02 cents, TRBO/DMR blows D-star out of the water (and yes, I own an Icom ID-880). Audio quality is much better, the FEC is far superior, and the layout/user interface is much more user friendly. ETA: Feel free to PM me with any questions you might have about TRBO. More than happy to help you understand it. |

The radio's were my problem from the get go. I always though Icom's VHF/UHF amateur gear was just junk and never really liked how cheap the microphones and radios felt. |

More than happy to help you understand it. Many thanks. I live a little west of St. Louis, and there are NO DMR repeaters anywhere near me according to http://www.dmr-marc.net/repeaters.html, so I have no chance to experience it. All of my "knowledge" comes from the Internet. There are a few clubs close by that are installing Fusion, and one of the clubs I belong to is putting in a D-STAR with both 2m and 70cm, but I'm not hearing anyone talk about DMR. Thanks for the IM offer. You may live to regret it.

I was looking at the Connect Systems CS-701, then found the Vertex VX-539. It would work for both DMR and for use as an extra duty radio. Has anyone looked at this one on here by chance? I've had an EVX-539 for about a week now: it's great. We have a statewide, microwave linked DMR network here, and I needed a 100% squeaky clean legal Part 90 portable for some volunteer work. I'll post to the HT thread in a bit with more info, but for now: -Software is free: get signed up at businessonline.vertexstandard.com and grab both the international and US version of the software. The international will let you program the Analog Wideband stuff for Amateur use. -Aftermarket programming cables are expensive at $50, but cheaper than VS branded ones at $120+ and work fine. I got mine from The Antenna Farm. -For the cost, the build quality is impressive. IP 57 weather proof, IS versions available. -Audio quality is good: no complaints out of a group of Motorola diehards, I'm happy. The price is steep new, but I just picked one up for $300 shipped with an extra battery, speaker mic, AA case and programming cable. I've thrown my lot in with the DMR folks for now. |

Quote HistoryNice. More and more DMR offering hitting the market. I think the multitude of radio options are what will make DMR win against System Fusion. It has already surpassed Dstar, and only because Yaesu is pretty much giving repeaters away is there even a battle. |

Motorola is ceasing production of the first gen TRBO radios in the next month or two so used prices should come down significantly. Paid $225 for this one…only thing it didn't have with it was the dust cover for the accessory connector. Of course, I already had the CPS and programming cable… |

Newer firmware solved this. And now with the gen 2 radios you can select tho is the radio in charge of timing control. |

I wish that there was SOME activity in the St. Louis area. I'd love to try DMR, but there's no one to talk to.
Which radio would be a good entry level choice, given that I'll be using primarily for FM for now? I do travel sometimes and may end up somewhere that DMR is available. |

Motorola XPR-6550, Kirsun DP-770, or you may want to wait a bit for some of the new lower cost options that are supposed to start hiting the streets in a few months. I would say CS-700, but if so I understand a new frimware is being tested (only a couple years late) and would wait until they are shipping with it. |

I love my 6550 and I've only had it for a handful of days. The RSSI meter onboard is something I haven't yet seen on other brands of radios. They are all cool though. |
