steve lazarDual Band DMR MobileReviewed on May 12,2022prior to use you should update the firmware using the CPS provided. this added additional contact space and APRS. DMR programming is different then classical input frequency , offset and pl tones. There are a number of Youtube videos demonstrating how to construct code plugs the Ailunce web page has examples of code plugs , CPS and firmware upgrades generally a very solid radio and would recommend.Little T.works greatReviewed on May 12,2022This unit is about the size of removable faceplates on radios which have them. GPS, dual band, easy to program. Looking to standardize on mobile radios installed in fleet vehicles.. it works greatKen Fongeallazsmall DMR radioReviewed on May 12,2022I really want a small DMR radio that is portable and easier to use in the car than an HT with an amplifier. It can be programmed very well on the walkie-talkie, easy to use, can use digital and analog mode, I have not used the analog mode yetNoel Lozadamini DMR mobile RadioReviewed on May 12,2022This mini DMR mobile Radio works very well, the sound is very clear, the most important thing is that it is easy to carry, easy to carry, it is very suitable as an entry-level mobile Radiodonald grubbsmini mobile DMRReviewed on May 12,2022Cool mini mobile DMR radio. Have only used it analog so far, received a good report on how it sounds. Have found a mike gain setting and we will see. Has a place on the side to plug in a different spkr mic, will try that , too. Actual size is closer to 4 3/4" x 3" x 1 7/8".Michael Shirlesmall radioReviewed on May 12,2022This radio has potential. It is a true mini mobile, so small that it is about the size of a control head (removable front). That is it's real draw even though it has just 20 Watt RF output. For DMR use, it works pretty well. It has a very small display that would be difficult to see in a vehicle and its analog FM operation is annoying. The radio is marketed to the commercial/business/public service arenas but not to US Amateur Radio community. It does not have the part 90 sticker but will transmit there. But it does support Ham Radio and is legally able to operate on the UHF and VHF ham bands. That was my interest in this radio, so the out of band operation was not important to me. Special mention of Retrivis customer service: It was surprisingly good. A China based rep Emailed me and phoned as well and over the course of 7-10 days, I was provided with tips and they wanted my codeplug for testing. So hopefully in time this radio will mature. My Evaluation (no technical specs testing) There are many issues with this radio but much of it could be fixed with better CPS and Firmware. I am fairly picky on radio operation and performance but cost is also part of of the evaluation for overall value. If you use it for DMR only and are willing to wait for CPS/firmware improvements and the cost stays below $200, this could be the answer to the removable control heads for DMR mobiles for Hams. Ham digital use is useful now but barely and not for what I envisioned, a DMR mobile in mdonald grubbsgood radioReviewed on Mar 30,2022This is a good radio. Seems to do what it says. APRS modulation can be a bit unstable. It seems my Kenwood and yaesu don't like to decode it directly but Digi decided it. It's a good radio for analog and DMR. They also seem to be rolling out some firmware updates, so that's promising. I like the length of the mic cable, especially considering it's for a mobile app and it's probably mounted quite far from your head Also, you can use the mic as a speaker, which is nice too.Gunnar NorénNice radioReviewed on Mar 20,2022Really a nice little (very little) radio. Feels price worthy if you want 20W and a mobile radio. Good sound. I now use it as my first radio at home and in my car just because it is a DMR and FM. Only sad thing is the software. It was not stabile but I loaded Radioddittys DB25-D and then also got function buttons 4-7 at the microphone. It is the same radio. Retevis had a better price with the combo with the magnetic antenna. Good!ALEX GARCESEXELENTE SERVICIOReviewed on Oct 30,2021exelente servicio me enviaron el cps enseguidaKevinRT73 And AntennaReviewed on Oct 20,2021i ordered while the on a holiday and theymailed as soon as they was back and they put up with me messaging then alot radio arrived quicker than expected radion came in 10 days and is well worth they money ive spent ive have had lots of good reports from friends well worth it
