DorothyGreat 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).MarjorieExtremely satisfied.Reviewed on Mar 14,2025Just what I needed. Extremely satisfied with product.LenGood goodsReviewed on Mar 14,2025Work great with OpenGD77 firmware.SelenaDMR radio at a reasonable priceReviewed on Mar 14,2025Quality looks very good and it is very small in size which is nice..DaisyFirst DMRReviewed on Mar 14,2025Looking forward to learning this radio so I can use it as a base. If it works out I will use another as my mobile because it is built like a tank and has great loud audio.DouglasWorks, good radio, software is easy to use.Reviewed on Mar 14,2025I like the radio. It is a simple old school type of radio that can do DMR. Some of the DMR radios I have, have more bells and whistles that I never use. Just set it up in the software or set it up with the buttons on the front, then change channels and it just works. And that's what you want in a mobile radio, simple to use will driving.BevisGood dual band DMR mobileReviewed on Mar 14,2025Good dual band DMR mobile rig. Programming can be a pain as it can’t use chirp, nor the same CPS as any other DMR radioHarleyMust get for dmr users that still use analog as well!Reviewed on Mar 14,2025Amazing radio overall! I especially love the the fact that it does analog and dmr the radio is built with quality parts, microphone works great with the key pad as well! The speaker is very loud and clear just very very satisfied with my purchase!AdamGreatReviewed on Mar 14,2025It is loud and I like it.LesleyWorks great, would buy againReviewed on Mar 14,2025Better than expected quality. It took awhile to program the DMR side of the radio due to being new to DMR. I would tell a fellow Ham Operator it's worth the price. I also bought the extended warranty. 73 would buy again
