Working Alone
Good dmr licence free radios. I wasn't able to program them yet tho so not sure about all the features . The speaker on them isn't great, audio is a bit low even with the earpiece that's one thing I would change. Not sure how they would do in noisy environments. Decent build quality, durable and look professional 👍
Fab dmr 466 radio works well good all rounder
Great radios, simple to operate, has more functions if you want to delve deeper, haven’t tried the range yet but I think around 2-3 miles line of sight
Están muy logrados son robustos y la comunicación es perfecta se pueden comprar sin ninguna duda muy buenos walkies
Para rádios de entrada de gama, fiquei bastante surpreendido pela positiva.Eles funcionam sem necessidade de qualquer programação, no entanto com o cabo de programação permite configurar encriptação, modos e muitas funções.
Good radios, with some advanced features, however, most of the advanced stuff requires a programming cable, and a software download. The cable is cheap enough, but there is (as far as I could find) an almost complete lack of documentation for the software. I did manage to get them working as I wanted, but it was much harder and more time consuming than it should have been.
Qualità costruttiva complessivamente buona. L'audio in digitale è discreto anche se, come già detto da altri, il volume è basso. L'ho programmata tramite un cavo Baofeng che, essendo una semplice connessione seriale tramite USB, risulta compatibile. Una caratteristica abbastanza noiosa, è che c'è una coda di circa un secondo al rilascio della trasmissione che rende la conversazione poco fluida. Probabilmente è una caratteristica che si può modificare da software ma per il momento non sono riuscito a capire come.
Muy robusto pero para cambiar las características hay que hacerlo mediante programación externa.
Bought this as a business radio. Software download from Retevis works fine allowing programming of radio parameters. It is light, feels solid and simple to use out of the box. Not tested distance yet but sure it will be good for my needs. The price was very good for the type of radio. It is NOT a CB Radio but a business communication radio. Do not confuse the two!
Verkar helt OK radio, känns bra, saknar dock bordsladdare vilket borde följt med. Kan vara svår att programmera om man inte är van vid DMR radios. Förvisso så är radion redan programmerad med 16 PMR frekvenser både analogt och digitalt.
The rt40 charge's via a usb socket on the base of the battery. A High power charger will not work with these units so a standard micro usb plug charger is all you need, they do not accept a fast charge. The battery does not need to be attached to the radio to charge if you want to do it that way.
Funcionan perfectamente. Buen sonido
J'ai été impressionné par la qualité apparente de ce matériel. Grâce au logiciel de programmation j'ai pu assez facilement paramétrer ces talkie-walkie.
È diventata un best buy , rapporto qualità costruttiva prestaIoni e prezzo top!
Die Retevis rt40 Geräte sind digitalfunktauglich, von sehr guter Verarbeitung und IP 68 tauglich. Die Verpackung der Geräte ist vorbildlich.
Klein, handlich, gut zu programmieren, DMR und encryption funktionieren super, gute Lautstärke. Dagegen unbrauchbar ist die VOX Funktion, man muss schreien, damit die Übertragung beginnt, sehr schade...
Ich nutze diese als Kommunikationsmittel bei der Motorradausbildung. Klappt gut. Sehr wenig Störungen
Die Geräte kommen mit dem nötigsten Zubehör, haben eine tolle Haptik und funktionieren mit dem vorgeladenem Akku auf Anhieb. Leistungen und Reichweite sind dem PMR Funk entsprechend.
Sehr gute Digitale PMR Funke. Mit der Software sehr viele Möglichkeiten der Individualisierung.
Das Gerät ist voll zu DMR Tier 2 kompatibel und von 400-470 Mhz bzw für den Amateurfunk frei programmierbar. Die Software dafür gibt es auf Anfrage beim Verkäufer.
We use this walkie talkie for a road trip across the UK and Ireland. We have 3 cars. If you're within a few hundred meters of each other, you should be OK. you'll get relatively decent transmission. Once you start talking about a couple kilometers distance or more, however, you're probably going to have issues. Don't cheap out on them, though. If you guys aren't super spread apart, its a good option.
I could not believe how clear the reception on the handset would be, my boss could hear me talk to a colleague inside our premises and he was over a mile away from our work, absolute value for money
The best walkie talkies available for the money, this is the second set I have purchased, not that any of the first load broke, but my staff have run over them with a forklift trick, left them in the rain, thrown them into a fire basically misused them to the point of destruction, these work so well, highly recommended
purchased by a secondary school for use by PE staff to communicate across a large site on sports day. Slim and lightweight, these fit easily into pockets. They seem to be durable
These radios are perfect for their compact size, lightweight, decent battery life, and clarity of transmission. Perfect for mounting on a helmet for kitesurfing lessons.
