my very first dmr.. very solid radio...


Good one

Great Product for the price

Good service, great product, fair price.

Nice Dual Band Radio

The radio is my daily driver. Owning it for 15 months it has not failed me. I also suggest getting a spare battery pack and I have the eliminator for the car. The Nagoya 701 antenna works great for this radio.

good tough radio

I run a small communications company and I hire them out to security companies,to date I own 16 of these radios because they are such a great performing radio, I have these radios in service since february with no drama, other than a few busted belt clip but that was due to the environment that where placed in

Great radio for the money

Well-built radio with everything you need to start into the world of DMR. Audio quality is great with plenty of volume available. Battery life is good given the size. Programming software is capable, but more suited for an experienced codeplug programmer. Overall, a great buy!

Great radio

Build quality on this radio is suppurb. I'm loving it. Audio is pretty good both rx and tx. Unfortunately I cannot test tx on dmr due to my license but analogue and rx dmr are both great. Does pick up a bit of interference in the cbd but that is to be expected. Overall a great handheld.

Great First DMR Radio

As this is based on the TYT MD-UV380 the build quality is good. My only criticism is the programming software could do with some code clean up but otherwise its a great first dmr radio

RT3S a success here

Everything working better than expected. In fact it has been one of the most fun radios I have had in 50+ years of being a Ham. Programming was straight forward but the features were so rich that you had to be careful. Now I can store my other HT and just use the RT3S. It does everything I could ask for. It is used while walking the dog, driving the car, sitting in the shack, and sometimes, when my wife lets me, in the living room while watching tv. BTW, it has taken a few tumbles since I got it. It just takes them in stride. No problems at all. I can see one of the Retevis mobile radios in my future. Thanks for a good product.

Solid radio, a couple drawbacks. Good price

Solid radio. However, the transmit button is too exposed and gets inadvertently pushed all the time.Other than that its a good hand held for the price. If there was a fix for the ptt button i would buy again.
