I've now had 3 of these radio's. 2 were gen 1 and the third is a gen 2. All are very well made, ease to program with very long battery life. The gen 1's I charged up as per instructions in the manual and didn't have to recharge for about 2 months and that was with quiet a lot of usage. Compared to other brands these seem to be quiet a bit heaver too and have a great feel in the hand.
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.
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.
