Being able to use both bands is essential for me as we operate around buildings and in cities as well as straight line of sight on highways and whatnot.

You can program it from keyboard, but much easier it's to use CPS software provided by manufacturer. Although, so far, my use has been mostly receive only, the battery goes for days before needing a charge.

Programming code plugs for digital repeaters can be a bit confusing but there is a lot of information on the web to help.

There’s also a demo of the radio working on both DMR and FM in my HD1 front panel programming video. I set up my pi star hotspot, and my interface is up but I can’t seem to figure out where to go from here. I was a little disappointed Chirp and Repeaterbook can’t be used to load repeater frequencies into the HD1 like with the Baofeng and other radios. The backlight has an ‘always on’ setting that has very little impact on battery drain from my experience.

The speaker on the HD1 is the best one I’ve seen in a handheld radio, super loud and really good quality audio, you will never struggle to hear this radio that’s for sure! these symptoms makes me guess that your radio is misaligned/uncalibrated and that's why you have these issues, try check my post here: https://auto-cb18.You could drop it and run over it and it would survive but it feels so nice in your hand that you will look after it. The AILUNCE HD1 handheld radio operates in analogue and digital modes using TDMA technology and is fully DMR compliant, Tier I and Tier II compliant. This is fantastic for those weekend fishing or camping trips and being a waterproof radio you really do not have to worry about it getting wet. DMR is a response to the growing requirements of companies and institutions regarding security and unwanted data leakage (information has the greatest value).

That was a hardware issue in the early radios, which has now been fixed in all new radios by the addition of a small ventilation hole in the back of the radio. The color LCD is nice and can be customized to show both bands (channels/frequencies) or one band and a clock.This issue has been reported to Ailunce, but they haven't given any official response which I think means it's a hardware problem that they're not planning to fix.
