FredericaGreat radioReviewed on Mar 14,2025A great radioLucyGreat radioReviewed on Mar 14,2025This mobile radio can use your existing MD-380 codeplug with minor mods. So glad I bought it. Nice signal from my base station aerial.DonaldRock Solid PerformanceReviewed on Mar 14,2025Bought two of these for a DMR business application. Also have about 30 RT3S portables. These mobiles are easy to program and perform well. Sound quality and available volume are excellent.BarryAwesome Radio for Fire/EMS and amateur radio!Reviewed on Mar 14,2025Awesome Radio. I use it in Amateur and at work as a Paramedic. Perfect audio and receive. It stands out in its class and works as good as my Motorola mobile. DMR and analog work perfectly in scan function. Great audioDorothyGreat mobile HAM radioReviewed on Mar 14,2025I bought and installed this HAM radio in my overland truck and it works fantastically. The programming software from Retevis takes a little getting used to but once comfortable it programs quickly. Could also be a good radio for a “go box” if using VHF/UHF (2m, 70cm).GustaveDMR radioReviewed on Mar 14,2025Works as it should, but there is no that goes into or on this unit left it blankMarjorieExtremely satisfied.Reviewed on Mar 14,2025Just what I needed.

If it works out I will use another as my mobile because it is built like a tank and has great loud audio.
