The power switch of the Ailunce HD1 seems to be a soft-switch not a true power switch. It can be tricked into powering up the radio in an off position. The radio will be on and you might believe it was off. This can cause the radio to be in your pocket and potentially transmitting and interfering with other station. The battery could get hot while stored and create a fire hazard. I have contacted Retevis in regard to this issue and they dismissed the case. Please test your radio and make sure it is off when turned off!!
We originally purchased a package of 10 of RT22 walkie talkies. took a few minutes to synchronize them and away our staff went. Seeing as we have more employees, we ordered another series of 10. Worked just the same. Exceptional quality! Light in weight, easy to operate and spans on long distances. Everything we wanted.
My first impression was that it was cheap, due to how lightweight and small it was. But the biggest problem I have is that it only lasted two and a half days. After two and a half days the PTT button stopped working, and it does not transmit audio. So now it is just a speaker. If you want a better mic that will work with the HD1 or RT6, get a Motorola PMMN4027
While this radio is definitely a step forward for amateur radio DMR hardware, there are some noticeable issues and limitations, and some feature currently lacking but hopefully available in the future.
1) Receiver Sensitivity: for a 10w radio, with great long range outreach, it has a very poor sensitivity for the returning weak signals from such range. they can hear you, but you can't hear them!!! at about .30microV it puts this radio to very cheap receiver standards. This is made even worse but a very sharp, low sensitivity squelch.
2) GPS features are primitive: Why not implementing auto switching or location of nearest channel based on the channel and radio coordinates? This would be a jewel and a deal breaker for a lot of traveling radio enthusiasts and could be used for locating nearby radio in simplex.
3) The display is on the dim side outdoors.
4) The programmable keys are lacking options. Zone could be added to allow quick Zone change without using the menu and many other options could be used but are not listed.
5) Missing a simple audio out or a simple audio in/out adapter to use with sound card or other devices.
6) Missing a small Bluetooth module?
7) Was the programming software developed by a student? So many bugs and issues it is ridiculous!
Please opensource and we'll get you a nice software rolling!!!
Overall a nice radio but not perfect and yet, soooo close....
Please Retevis/Ailunce, work on the firmware or opensource it so we can do it!!!
After 2 days : white screen ... return to amazon
second rt 82 :
After one month the « central censor buton « is not so good, a reel button is more but no reel buton on rt 82....
You can’t access vfo in all case ( mr or ch) very boring...
I've only had it a few days so still learning about all it's features but it's very well built, quiet heavy for it's size. The display is bright and easy to read and the menu's are also easy to follow.
The HD1 GPS has been a solid radio for me in terms of ruggedness. It truly lives up to its IP67 rating as I actually submerged it in water for 30 minutes. The HD1 seems to be very tough. I accidentally dropped it from about 30 feet onto concrete and it kept on working. The battery did pop off but I put it back on and it kept on going. I've used it for both repeater communication and in simplex mode. No reports of bad audio or breakups. Programming from the keypad is actually quite easy once you get use to it. The programming software is functional but could use some updates. I'm sure it will mature in time. The display is a bit dim for my taste when in direct sunlight so hopefully this is addressed in future firmware updates. The GPS is very accurate and I hope Retevis develops an SDK so we can create some mapping software. Overall I think it's a great radio and Retevis has been responsive to feedback from users, fixing bugs, etc.
I really like these walkie talkie radios! Me and my son love playing with them and we have had loads of fun with them!
I love the modern design of them too, they are really fresh looking and have a rubber texture so they don't slip out of your hands!
I highly recommend these PMR radios! Really inexpensive and very well made and a lot of thought has clearly gone into these little radios! You can charge them via USB too! Amazing!
Don't hesitate in buying these!
The RT6 gives me peace of mind when trekking in wet weather conditions, it has survived being submerged and in a shower.
The stock antenna is a good match to the radio, and I've had good reports on audio when working repeaters 15 miles away.
Reception of the international space station - both audio and SSTV (decoded using phone app) has been excellent.
The build of the radio feels very strong, and the battery life has been good - after three weeks casual use I've only recharged it twice.
This model is in the CHIRP menus, making it easy to programme.
Using this for a marine handheld. Had to do some research as to the frequencies, and buy a programming cable, but the process was easy, if tedious.
Works great! As good or better than the $200+ ones I have used. Parts are less expensive too.
the order is sure arrived. Fastly. Our frist Tests with the Radios are well in Point of Quality of the Hardware, simple programming
with the Adapter. The Receiver are stronger than our olds MOTOROLA GP1200 on 70cm Band. The sending are clear and more
better than a Baofeng.
I bought 16 of your rt6 waterproof radios we are really happy with how they are working for us we use them as a group for coyote hunting with dogs the only thing I have notice is that the batteries won't last all day on a long day of hunting for example they might last 7 to 8 hours I don't want to loose any range power with them if u have any suggestions so I can 10 hrs of life that would be great but other then that I think the this product works great
