Customers say
Customers find the two-way radio works well, with one mentioning its 6 programmable actions, and they appreciate its great reception and reasonably clear audio. The battery life is sweet, and they consider it good value for money. The programming capability receives mixed feedback – while some find it straightforward, others find it too difficult to program. The headset adapter availability is also mixed, with some customers noting it’s not included.

Nice inexpensive air-to-air radio
For the low price this costs, I was concerned it would not be a good radio, but I was pleasantly surprised. Once you get past the confusing manner in which you program the channels and frequencies (they could do MUCH better with their manual) it actually is a very nice radio. The range is quite impressive, and I radio checked it with aircraft miles away, and it all came back 5 by 5. It has only a couple of extra features like a flashlight (?) mode and a timer… but none of the extra stuff like VOR nav that you see in far more expensive radios. If you want an air-to-air only unit, this is it. I highly recommend it.

Headset adapter is not available
First and foremost, this is a great radio. I have several Wouxun radios, ham and GMRS models. The superheterodyne receiver in the Wouxun radios makes them by far superior to other “Chinese” radios. I purchased this KG-S74A to replace my aging Icom IC-A4.. The reason I have given only3 stars is the fact the headset adapter shown in the listing and in the manual is not available.I contacted Buy Two Way Radios and was advised that they do not carry the adapter and they are unaware of where I can get it. I purchased the radio for use on my ultralight and without the adapter it is not usable for that purpose. So, if you intend on using the radio merely for ground to air communications it’s a fantastic choice.

This radio is wild
I came from having a Bendix King KX-99 brick of a radio. In contrast to another reviewer, it took all of 5 minutes of reading the manual to learn ALL the buttons, aside from the PTT, are programmable. I was able to even customize the welcome message which is super corny but a nice to have. Yes, the squelch buttons from factory is set up pretty uselessly as its the top red button and only allows you to go up, but I programmed the two side button short presses to command squelch and the long presses for something else then the red button long press for guard. For the price this thing is great, my only suggestion is to do better to remove the side panel for the headset adapter. Gotta find some thumb screws for that one. Seriously, dock and usb-c charging, and it comes with an adapter for a headset….. Game changer.I’m gonna follow up with an update for its battery life soon, but from what I can see I expect good things.Update after one month: Haven’t had to charge it, battery life is pretty sweet. I use it all the time with students to listen in on comms and to get weather without cranking up the plane. It just does the business. I love that I can save frequencies and name them whatever I want. If you’re an instructor or a private pilot, the size is great for flight bags and simply put the radio can compete with pretty much any aviation transceiver out there. Sure you need an adapter for the headset plugs, but honestly comparing it to the sporty’s pj2 or iCom radios, it’s a fair trade in my eyes.1 year update after original post in June 2024:Radio holds up great. Battery life is as good as I thought it would be when I purchased. Have already used it to get clearances, ATIS, and even during a 7600 situation. I have already recommended this product to colleagues and friends. Compared to Sportys Pj2, it’s objectively a better radio. The USB-C charging functionality is incredibly convenient and I’ve probably charged the thing maybe thrice since owning it.

I am not a pilot. I bought this radio to listen to airband radio traffic.
I am in a metropolitan area with a major airport and a number of small airports all within 8-10NM. I am basically using the as a scanner. It works great for me. I have given only 4 stars because I have not (and will likely never) transmit so I can’t address that functionality. The radio comes with everything one would need: a charging cradle and power supply (though the radio has a USB-C port for direct charging), belt clip, BNC adapter for different antenna connectivity, a headphone/mic adaptor (though I am using only the headphone side). Some other niceties as well like a rubber seal to replace the USB-C port cover making access to the charging port easier (though you then sacrifice the IP67 spec).It’s my first handheld radio and IMO this thing seems solid. The button action and feel is great. As a beginner I like the audio feedback with button entry though both the beeps and voice guide can be turned off. The radio is highly configurable including the ability to assign pretty much any function to three of the buttons. Each of the three can be configured to two differnt functions, one for short press and one for long press. So there are 6 programmable actions. This configuring is easily done and well described in the User Guide. The stock antenna seems fine but I have not tried others.I mapped frequencies to channels by hand. It was a little tedious but straightforward. The User Guide is very complete and reasonably clear though there was some trial and error involved for me. The radio is pretty new and not (yet) supported by CHIRP. I did not try Wouxun’s own radio programming support and did not even buy a programming cable. Looks to me like it will take some more research on my part to understand the nuances of programming support (both hardware and software) for this class of radio so I’ve avoided it for now. I am not a power user.I am defintiely happy with this choice. There are cheaper solutions for airband support and way more expensive ones as well. The cheaper radios that support airband seem to be GMRS radios in which the VHF AM support is some kind of and-also feature. But I wanted a radio that was specific for airband thinking (hoping) that I’d have a better chance of getting a device that works more reliably. FWIW, from someone new to this, I would definitely recommend this radio.

Does not come with headset!!!!!! as seen in Photo
The stock photo shows a headset and even the enclosed booklet states that an headphone is enclosed but that is not true and I feel sad.
