Best PMR Radio I've used.Reviewed in United States on Sep 03,2020We bought a couple of these to use at the farm and didn't expect much but the radios are amazing quality both in audio and physically, it can be very loud I didn't have any trouble when using it around loud machines, very good radio would definitely recommend it to anyone.programming software for retevis rt 24Reviewed in United States on Aug 27,2020thanksGreat simple radios for good priceReviewed in United States on Jun 08,2020Retevis RT24 is great set, radios are very simple to use, durable, has Li-ion bateries and big antena, that makes bigger range than similar radios. With my old sencor PMR446 was tested range 3,5km in open field, with this retevis 6km in the same terrain, so I'm fully satisfied. Programmable 16 channels are gret feature, you can have same frequence like other friends, or not for more private communication. The battery lifespan is pretty cool, whole weekend on, without any problem. I miss only one thing sometimes, the "ringtone" button would be nice touch. Meets the conditions of the law of use in my country, what baofeng doesn't. Overall I'm verry satisfied, great simple radios for great price.GizzyThis is a smart buyReviewed in United States on Mar 14,2019It might be inexpesive but the quality is far from cheap.
