4 Pack Radioddity GA-2S Long Range Walkie Talkies for Adults UHF Two Way Radio Rechargeable with Micro USB Charging + USB Desktop Charger + Air Acoustic Earpiece with Mic, for School Retail Business

I purchased the 6 pack of Radioddity GA-2S radios to replace some well worn BF-888s . They are used by adults and teenagers during camping, fishing, and scouting events. Here is a summary of how they tested. I set all six transceivers , chargers, cables, and headsets on my bench. After unpacking I had one antenna missing from one of the boxes. I replaced that antenna with one from my Anytone 3318A dual band HT just for testing purposes. The batterys measured 3.8vdc out of the box about 80% charged so I pressed on. I downloaded and installed the cable driver and programming software from the Radioddity website successfully with no issues on a WIN 10 laptop. A programming cable was provided with radios. The radios work out of the box but you MUST program them for use to your application as the 16 factory channels frequencies are not legal for use in N. America. For testing I programmed in two local 70cm Ham repeaters ,2 Ham simplex channels and 12 GMRS channels. All six radios talked to both local Ham repeaters 8 and10 miles away with good audio and signal reports. All six radios communicated with each other on the two Ham simplex channels at both high and low power well at 1.5 miles. All six radios communicated with each other well on the 12 GMRS channels at low power at one mile. All six radios functioned well and all controls, indicator lights, and voice channel annunciation worked fine. Comments from field testers (2 GMRS licensed scouts,2 Hams, and two GMRS licensed adults): 1. Pros: Good audio loud and crisp, good feel in hand, nicer antenna than older BF-888s, scan function actually works. Excited about the ability to charge in car with new Micro USB port and provided cable included with each radio. 2. Cons: Not a spring loaded belt clip so though functional a bit harder to remove from belt. Bench tester comments( myself): All charger bases and USB to MicroUSB cables worked. All headsets worked. All batterys charged in their bases in 2-3 hours to a total voltage of 4.2vdc. Will be longer with dead battery. I charged one unit in car with micro cable and it charged in 2.5 hours similar to the base units. Unlike alot of budget radio import BF-888 similar models out there the GA-2S actually puts out 2 watts in high power mode and drops to about 800 milliwatts - 1 watt in low power mode on my test bench. Nice. Note : The Radio charged fine in the MicroUSB port but did not give indicators as described in manual.( YES I read it.) When you plug cable into radio MicroUSB port and then into the USB 5v source the light on radio goes red. After charge complete the light just goes off. In the manual its says there is a green , orange , yellow transition for the indicator light...negative as of this radio firmware version. Radioddity to do list..!! In closing : Great deal for the money. Has clean signal and clear audio for its class of radio. Programs with CHIRP. Can charge without stand if mobile. Only negative but not a failure...MicroUSB port indicators should act as manual states. Only issue: Missing one antenna but since I have owned two GD-77s for a year and know how well this vendor supports its users I did not subtract from review score knowing they will make it right .

These radios have a pretty long battery and charge quickly. They have 16 channels that are easy to change to. They don't go that far in range, but they are pretty clear when you talk. They are more for adults than kids. They are as big as a ruler.

These are really great little UHF radios, especially considering the insanely low price point. Construction is solid and they feel great in hand. Programming is easy with CHIRP using the same cable I originally bought for my UV-5R units. So why buy these units when competing radios with digital displays are available for only a marginal increase in price, you might ask? Because these are idiot proof: after programming them with CHIRP I can hand one to a family member or coworker and there is no chance for them to accidentally change the settings or switch privacy codes (for example) when they go "exploring" through the menus out of curiosity. All they can do with with the GA-2S is change the channel using the rotary knob. That's it. The scanning feature is great, although without a display you'll have to guess what channel you're hearing if you want to switch over to it and you don't already know the channel from recognizing the voices. I deducted one star because there are a few minor nuisance issues with the design. For example, the channel numbers on the rotary switch are hard to read; Radioddity could easily solve this with a bit of white paint in the number indentations. Also, the belt clip doesn't have any spring or hinge mechanism and requires flexing the plastic in order to remove it from a belt. The batteries do feel quite light, meaning they designers could've used a larger cell (more power) in the same housing. Finally, the charging base is obviously produced in the same factory that a lot of the Chinese brands are using, and it is marked as "110/220V INPUT" even though these chargers only take USB power...not wall voltage. In truth I'd have preferred the chargers that had wall power connectors, although the radio variants from other brands here on Amazon with those better chargers seemed to have inferior features overall. None of these criticisms will prevent me from buying additional sets of these radios, and it really is unfair to expect perfection at this low price. Considering that they only cost $14/each including tax and shipping, these minor concessions are hardly worth obsessing over. They are an excellent value. Just buy a set--you will not be disappointed.

Salve a tutti ragazzi. Oggi andremo a recensire una coppia di radiotrasmittenti marcate Radioddity. Nello specifico andremo a recensire le Radioddity® GA-2S Coppia Radio UHF 400 – 470 Mhz. Si tratta in sostanza di una coppia di radiotrasmittenti che operano sulle frequenza UHF. Ma andiamo ad analizzarle nei dettagli. Procedendo all’unboxing all’interno delle due identiche confezioni troviamo: - Radioddity® GA-2S Radio UHF 400 – 470 Mhz; - Batteria; - Clip da cintura; - Laccetto da polso; - Cavo usb per la programmazione; - Caricatore per la batterie con connettore USB; - Auricolare con tasto PTT e accessorio trasparente; - Manuale d’istruzione in lingua inglese. Superiormente troviamo due rotelle. La prima serve per selezionare il canale di trasmissione da 1 a 16 mentre l’altra serve per accendere la radio e per regolare il volume di ascolto. Lateralmente troviamo il classico tasto PTT per azionare la trasmissione e al di sotto di esso abbiamo un piccolo tasto gommato utile per disattivare lo squelch della radio. Dal punto di vista tecnico diciamo subito che le radiotrasmittenti sono in grado di trasmettere e ricevere in tute le frequenze comprese da 400 a 470 Mhz (UHF). Vi consiglio di programmarle sulle frequenze legali che avete intenzione di utilizzare in quanto di fabbrica sono impostante su frequenza dove in Italia non è possibile trasmettere. La programmazione può essere facilmente effettuata grazie al cavetto di programmazione usb fornito nella confezione attraverso l'utilizzo del software "Chirp" liberamente scaricabile da internet. Con la programmazione possiamo selezionare la potenza di trasmissione (max 2W), il tono (CTSS o DCS) o l’ampiezza (FM o WFM) per ogni singolo canale. Concludo dicendo che si tratta di ottime radiotrasmittenti dal prezzo molto accessibile ma ci tengo a precisare che per poterle utilizzare in Italia avete bisogno della licenza radioamatoriale anche se le programmate sulle frequenze di libero uso PMR in quanto anche sulla medesima banda la massima potenza di trasmissione è di soli 0.5 W. Visto l'ottimo rapporto qualità/prezzo non posso fare altro che consigliarvi questo prodotto. Come sempre vi lascio con qualche foto esplicativa del prodotto. Se avete domande o dubbi vi invito ad inviarmi una domanda. Sarò felice di rispondervi. Ciao e alla prossima recensione !

These radios are, for the money, really good, but that assessment comes with multiple caveats. First up, as supplied these are not suitable for license-free operation in the UK or elsewhere. While they could (with some effort, see below) be set up to inter-work with, e.g. PMR446 sets, they won't do that "out of the box". As supplied, they are set to a mixed set of frequencies, using wide FM modulation at a couple of watts. Some of the preset channels might be OK if you have a HAM licence (I forget the exact ones that were set), some not, but none are OK without a licence. Do NOT expect these to work with PMR radios, as supplied, they won't. (If you want a nearly-identical radio, but configured for license-free PMR446 use, look at the Retevis RT24. As far as I can tell they're extremely similar except they have a different PTT button, an antenna you can't remove (without tools) and power fixed to 0.5W ERP, on the 16 PMR frequencies.) As another (extremely helpful) reviewer pointed out, to get proper use out of these you have to get a programming cable for them, and get yourself a copy of CHIRP (which is free). I used a Retevis branded cable bought to go with different Retevis PMR radios - it cost about half what the Radioddity brand cable did (on Amazon) last I checked (although someone said Radioddity will send you a cable on request - I haven't asked so can't confirm). The cable I have works without any additional drivers with a Linux laptop, and I would expect it to work also on a Mac. (People seem to have problems with these cables on Windows. They typically use FTDI or Prolific serial comms chips, and there are lot of cheap clones of those. A few years back, Windows drivers started refusing to play nice with older, or clone, FTDI chips, and Prolific clones suffered a similar clamp-down. The fix is to revert to an earlier version of the driver, or get a cable with a genuine (and recent) FTDI or Prolific chip. If the cable is suspiciously cheap, and "doesn't work" with Windows, it probably has an old or clone chip. Clone or old versions can be made to work, but it's a pain.) If you set these radios to narrow FM, on PMR446 frequencies, set a limit on transmit time, optionally set CTCSS or DCS (N) privacy codes, and set 0.5W output, technically they can interwork with PMR446 sets, but it's a reasonable amount of hassle, and still not legal because these sets are not licensed PMR radios (they have removable antennae for a start). There is no control on the radio itself for the CTCSS or DCS tone/code ("sub-channel") - you get whatever you pick for each of the sixteen channels when you program it. If you don't know what you are doing, it would be very easy to set these up in such a way as would likely get you into trouble - for example, over-power and/or overmodulation on PMR446 frequencies, the latter of which would be quite obvious on any PMR446 radio within range. At least one reviewer reported great range with them as supplied, in Snowdonia, and that's not really surprising as they come set to 2W, on probably-uncontested channels, with broad modulation, and open, high ground is ideal for UHF radios. I would not, though, use these, as supplied, to transmit in the UK/EU, you have to configure them first, and you can only do that with a programming cable. The configurability does mean that it's easy to make them fool-proof. For example, you could set all channels the same. Or you could set them to use the same base channel and different CTCSS tones on each "channel". Or whatever - they're super flexible. Each channel can be individually configured for frequency, power output (0.5W or 2W), modulation bandwidth, CTCSS/DCS. On the subject of the antenna, the supplied ones are OK, but they're a bit unwieldy - they jab you in the side if wearing them on a belt, and get in the way if dangling them from a wrist strap. I have four of these radios and no two of the supplied antennae are precisely the same physical length (though the wire inside them probably is). I replaced them for general use with some stubby antennae, that are also less fussy about orientation. If you like, you can attach a BNC adapter and run cables to proper aerials. These radios are super-cheap and simple, and fun for HAM use, if you don't mind that the radio itself has barely any controls. They could function as "prepper" radios, at a pinch, but their dependence on a computer for setup, and their limited power, makes them less than ideal for that. They seem like they were designed to be a kind of general purpose personal recreational or business radio that can cover all the bases, without having to have multiple versions in different territories, but otherwise stripped to bare essentials. The supplied accessories are a mixed bag. The charging bases are fine, if cheap and cheerful, likewise the (rigid) belt clips, and the antennae aren't too bad. With the wrist straps, it's best to add stitching at the bit where they join the thin part that goes through the hole in the radio, a couple of mine fell apart at first use, and the way they are made is very poor - the wrist strap braid is just melted together at the end where the thin string loop is joined, and the join to that is simply a knot in the thin string pulling against a hole in the braid. I have stitched all of mine, now. The "secret agent" style curly-air-tube earpieces look the part, but are super quiet and have very poor sound quality, at least that's how the ones I got were. The mics are OK but the earpieces, not so much. The mic and speaker built into the radio for traditional handheld use, though, are absolutely fine - excellent, in fact. The radios feel solid in the hand and appear well-made, built on a metal chassis. When the wrist straps broke on mine, they dropped from bicycle handlebar height onto a concrete surface and suffered no damage. They're clearly not particularly "ruggedised", or waterproof, but they've a quality feel. For the price they are excellent. Battery life is excellent, and you can charge them on the supplied bases. There's no mains adapter supplied, the bases are powered by USB-A. You can also charge them via micro-USB plugged into the radio, handy for charging in the car etc. If you had spare batteries, the design is such that these could be charged in the bases without the radio attached. The spare batteries appear to be listed as "discontinued", but I have found Retevis RT24 batteries to be nearly identical, and they fit and work fine. The scanning feature is weird. They scan the channel slots as configured, when scanning is activated, but only if you set the channel switch to 16. If you leave the "scanning" feature set to its default behaviour, and leave the radio set to ch 16, it goes into scanning mode after a short idle period. This means that it takes a relatively long time to respond to transmissions on that channel, as it has to go around its scan until it hits ch16. It's not *at all* obvious that this is what it's doing, it just seems like it has become mysteriously laggy and unresponsive. I have turned off the scan feature on mine. Again, you need the programming cable to do this. Overall, nice radios, with the low price more than making up for any niggles or missing features. However, if you're looking for something to use for PMR446 out of the box, or don't like the idea of having to hook them up to a computer and reprogram them before you can use them at all, then look elsewhere (eg the RT24, or more expensive PMR sets with screens and controls for sub-channel setting.) At the price, I think these are very good value, and I like their simplicity.
