I haven't dared to try this because Ailunce sent me this radio for free to test and review, and I'd hate to have to go back to them and tell them I broke it. DMR radios pulse on and off when transmitting, which can manifest as a helicopter noise on transmissions if you’re using an audio accessory with inadequate shielding. Dual Repeater Slots and Dual Point-to-Point Slots: The HD1 offers dual repeater time slots and dual point-to-point time slots, enabling efficient communication and maximizing the use of available resources. You need to be appropriately licensed to use this radio, and it’s not legal to use it on licence free channels such as PMR446, FRS, GMRS, or MURS. You can change the settings for both VFO’s separately in the settings menu, the menu has 11 main settings with more setting within them, they are as follows.
I don’t have test equipment to give accurate results on this, but the sensitivity of the HD1 definitely is comparable to all my other DMR radios including the TYT MD-380 and Motorola DP4800. The colour display looks good and works well, and I especially like the fact that it shows the battery percentage on screen all the time. Upgradeable Firmware: The radio firmware can be upgraded, ensuring future compatibility and allowing for potential enhancements and new features. DMR is a response to the growing requirements of companies and institutions regarding security and unwanted data leakage (information has the greatest value). I believed all the YouTube review channels that touted their Retevis supplied HD1's as the best thing going in radio.
While it does not have some of the whistles and bells of an AnyTone, it does have a little more RF power for the fringe areas. A valid product review is one where you have personal experience or knowledge of the product that you would like to share with others. Multiple reviews of the same product by one person will unfairly bias/skew the product average rating numbers.
On the TYT MD-380 with TyMD380Tools firmware, you can very quickly and easily type in any talkgroup and start transmitting within a few seconds.
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 first one I’m going to mention is that this radio has a proper frequency mode where you can spin the channel selector or type in a frequency and start using it straight away. I have no doubt that the units they received from Retevis had gotten a very detailed QC inspection before being sent out. If you hadn't heard of it already, the Ailunce HD1 is a dual band DMR radio that covers 136 to 174 and 400 to 480 MHz. The CPS is not intuitive and it's hard to find good instructions on how to get a good code plug made.
This is very annoying and seems to be caused by the radio still detecting a signal on the channel even though it’s supposed to ignore it if the CTCSS doesn’t match what you have set. Commercial radios like those made by Motorola and Hytera don't have this feature at all, except in the case of the TYT MD-380 which had unofficial firmware made that does support this. On the other hand, I was frustrated for many weeks in being unable to hear live transmissions that were being routed through local FM repeaters. IP67 Waterproof: The Ailunce HD1 is designed to be waterproof and can withstand immersion in up to 1 meter of water for 30 minutes. I Did some Power tests on the Ailunce HD1 and can confirm that on the 2 meter FM band that I tested I got.If you want to watch the video version in your language, it has full subtitles so you can use automatic translation on YouTube. I don't know if the battery actually has that much capacity, but the radio does seem to have excellent battery life, especially if you turn the power down to medium instead of using high power all the time. I have only had HD1 for a few weeks, but I feel that I have gained enough knowledge to provide honest opinions.
Great Deal
