Beoordeling RETIVIS RT3S

martin1947 on Oct 17,2018

Een goed product software werkt super snel gebruikersgemak is ook heel goed ligt lekker in de hand. Helaas niet spatwaterdicht en het zwakste punt is de riemclip deze is al in korte tijd 2 keer afgebroken. Positief is de duidelijke display met mogelijkheden. Ook de korte antenne werkt prima.

Best Radio I've ever owned

Lmontano on Oct 16,2018

I'm new to the radio world, I've own other radio walkie talkie type and those worked too, but not like the RT3 I work in heavy concrete buildings and cell signal sucks. But not for my Retrevis RT3 I can be heard crystal clear in basements and distances my other radios couldn't come close to.. Awesome job!!

good

Nice little DMR radio, excellent value for money

Very robust, dropped down twice and nothing bad happened. Sound quality is very good, both transmit and receive. Sounds like a much more expensive radio. Operates on analogue as well, which is very nice since you can have both analogue (many repeaters out there and many radios) and DMR on one device. You absolutely need the programming cable to configure. Note that you need a license to use it, such as an amateur radio operator license, depending on which country you line in. The only thing I don't like is that the battery only lasts for two days in listening mode or one day if you transmit as well, so you need to put it on the charger frequently AND the charger is really slow, takes hours to charge fully. If you intend to use it in the field often, buy a second battery (which can be a challenge due to the recent strict post legislation). Other than that I really love this radio and wait to see its long term reliability.

Really nice radio,defective out of the box, but immediately replaced by Retevis.

Item came on time, but when I was using it I noticed that when pushing the PTT button, the screen would completely distort and then go white. I had to turn radio off and back on to fix this. So,back it goes. Bad QC? Contacted Retevis, they responded in a timely manner but wanted me to take a video of the issue and sent it to them. If I buy an item I want it to work out of the box. So I will return the radio. Update: 9/21/18. Immediately after I posted my review, I was contacted by Angela from Retevis Direct and they shipped me a new unit, no Questions asked. I received it yesterday and I must say I am so happy and excited, Retevis really stands behind their products and they want the customer to be 100% satisfied. They apologized numerous times and I am really impressed by their customer service. This is my 2nd Retevis product and I will be a customer for life after this experience.

starsGood device for cost and use.

I have digital and analog devices so the setup was easy out of the box. The device runs and operates as expected to and the battery so far has been lasting 2+ days depending on use. The only issue I have was not being able to add channels from the device, but being able to edit them is possible. The other features of the radio seem a little confusing at first, but once you get past the learning curve it's much better. Overall it's a great radio and I would definitely recommend it.

Top item for less money

Chinese manufacturers have arrived in the luxury class. This device does not need to hide from brand manufacturers. The large-signal immunity is perfect. The storage facility, and the battery life is better than the brand-name manufacturers. Qualitatively better than any ICOM, YAESU, or similar device. Have the device now for 3 months and I am absolutely satisfied. Die Chinesischen Hersteller sind in der Oberklasse angekommen. Dieses Gerät braucht sich nicht vor Markenherstellern zu verstecken. Die Großsignalfestigkeit ist perfekt. Die Speichermöglichkeiten und die Akkulaufzeit ist besser als bei den Markenherstellern. Qualitativ besser als jedes ICOM, YAESU oder ähnliches Gerät. Habe das Gerät nun seit 3 Monaten und bin absolut zufrieden.

The Next Version Needs to be Dual Band

W6CSP on Dec 25,2015

I strongly recommend the designers start working on a dual band unit (if they have not already started.) Thank you

GREAT
