MGDB123Nice cheap radioReviewed on Mar 03,2025Works well as a base station in the garage. Not so well in vehicle, excessive interference which could be from electronics or the vehicles radio antenna. Either way it’s a pretty great little radio and easy to set up manually.BoDeventeGreat little radio for the right priceReviewed on Mar 01,2025Great little radio for the right price. It says 50W and that's what it does. Plenty of features. Was able to program utilizing their software and cable on Windows 11 machineFredseems to be a great little radio !Reviewed on Feb 20,2025really like this radio ! Also liked the price and the fact that the programming cable was included ! It was fairly easy to program "manually" but the computer cable and the software from Retevis really made it easy ! Good choices on the power options, too. usually run in the MID power , for all local stuff, but the HI power of 50 watts is there if you need it !CoyotesilencerNice simple to set up package.Reviewed on Feb 17,2025This is a good radio for the price. The included antenna works well. I am consistently getting into repeaters from 30miles away. Receives clear enough. For the price it is great to have and keep in a vehicle. I did have to adjust the settings to get it to accept more frequencies/bands. Programmed with CHIRP easily with the INCLUDED CABLE. I ordered a programming cable separately because the specifications didn't list it as coming with one. It did in fact come with the appropriate cable.atomic hamsaladexcellent valueReviewed on Feb 15,2025The retevis rt90 is an excellent value in a mobile dual band radio. A much higher quality than most Chinese 2 way radio. Easy to program with retevis software. Radio is easily programmable for MURS, GMRS as well.David B. MilewskiFantasticReviewed on Feb 10,2025Terrific little dual band. Easy to program ONCE you understand the icons buttons Great audio reports on this. Only drawback is it gets pretty hot running on high power and transmitting extended time.Morgan A.Amazing Deal; Great RadioReviewed on Feb 10,2025I bought this for my truck. I have a few Yaesu radios as well as other Chinese TYT radios. This radio is great so far after a week of using it. If you are comparing this radio and the Anytone radio, I would recommend this one just due to price. Giving five stars because it fits my needs.Justine WaltersNice radioReviewed on Feb 04,2025Awesome radio, I have a bunch of dual band ham radios and this one is excellent and unbeatable for the price!!! Excellent transmit and receive audio! Buy itRandyGreat little radioReviewed on Feb 04,2025Was going to go with an expensive Radio glad I didn't. This little guy does great super bright display. Easy setup so happy with my purchase think I may get a couple more. Easy to use really don't know how you could do much better unless you just feel the need for more power but this little guy really gets out there.PaPawsProjectsThe RT90 Exceeded my Expectations !!Reviewed on Jan 28,2025This is my second one. Bought one for the truck and one for the house. Works great, great reports, sounds good. Don't like the mic hook, just put a standard knob on the back like everything else.
