Product Information

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. To me, this is important because it's a potential safety issue if you ever need to use the radio in an emergency, and an annoyance if you ever want to use the radio around other people who are transmitting on theirs, or anywhere near a radio mast. If a review is posted that you believe is unfairly critical of your product and you wish to respond with useful information contact eHam's Product Review's Manager to request the addition of an "eHam. This is a problem for some users, particularly those who use analog internet linking systems like echolink or IRLP. This is useful in amateur radio because you should always check that nobody is already using the timeslot you want to use on the repeater before transmitting.

The menus are easy and not complicated at all to learn and unlike most DMR radios, this one is "field programmable". Another thing you have to watch out for is that the HD1 uses a direct conversion receiver that is very easily desensitised.They are still working to fix any remaining bugs and add new features to this radio, albeit painfully slowly. You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice.

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. I chose this instead of the higher end Motorolas or Kenwoods because of the fact that these are dual band (UHF/VHF) which I hate about the higher end ones only being one band.you will definitely not be disappointed, the build quality is incredible and I’m sure I will be using this radio on a daily basis for many years to come. But since most amateur radio traffic is not mission critical, this is not a deal breaker for many hams. DMR Compatibility: Compatible with Motorola Tier I and Tier II, as well as ETSI digital protocols TS 102 361-1, -2, -3. Code plugs are a challenge for anyone new to DMR; fortunately this radio has a big following and a very helpful Facebook group that is actively monitored by the Ailunce English speaking staff in China.

The lack of any easy and quick way to switch talkgroup means that you either have to program the radio with a channel for every talkgroup on each repeater, or you just have to put up with it taking a long time to switch talkgroups. Encryption is something that’s not really relevant for amateur radio, but a few people have asked me about it so I thought I’d include it here anyway. To build the largest and most complete Amateur Radio community site on the Internet - a "portal" that hams think of as the first place to go for information, to exchange ideas, and be part of what’s happening with ham radio on the Internet.To me this is a fairly minor issue, since you're not looking at the screen most of the time, but it’s one that does seem to annoy a lot of people. 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. There are proper marine radios available that are built for that purpose and have the correct channels already setup for you.

maximum output power with fully charged battery on high setting does not exceed 7W for both UHF and VHF (even with 50W specialized resistive load) - should be 8W/10W and I do not know of any way to adjust the factory calibration right now. Programming was pretty straightforward with the included programming cable and downloadable CPS software from Retevis. And there are many related videos on YouTube, and I can now fully enjoy the functionality of the transceiver. The radio will work with speaker mics and other accessories made for Motorola radios with this connector, but you do have to be careful because these were probably all made for analog radios. I bought the lapel mic with it as well and both looks and feel it reminds me of the Motorola's we use at the Fire Department.This solution enabled a quick expansion of the communication system, remote management, sending SMS messages, GPS position, telemetry and encryption. 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. The speaker mic and programming connector on this radio is one that you may have seen before if you’re familiar with Motorola’s radios. As such it could be a "Rosetta stone" for C6000 and C7000 differences in code setup if it was possible to decompile the V2 firmware.
