First Impression Of The Ailunce HD2 DMR Handheld Radio.

The HD1 is a good radio, and Retevis improved on an already successful design, notably adding a USB-C port and Bluetooth. In this video I show you the radio compared to the previous model, along with a bit of DMR channel programming.

7:26 DMR uses less power because the radio is only actually transmitting half the time you're holding the PTT due to TDMA. 30ms of time for 1 timeslot, then a 30ms pause to allow traffic to pass on the same frequency for the 2nd timeslot. It flips between these rapidly.

[norrinradd]

I've seen several videos, the features appear to be plentiful, but several reports claim spurious emissions. Thanks for sharing.

[BobBob-ilku]

The orange alarm button can be disabled in the software FYI

[sergiocavazos]

I have both. for me, hd2 has much better reception, can "work" with the screen in the sun, the center dial works a little bit better (yet slow response), the c usb for charging is good, the antenna seems to me with better swr, bluetooth is nice to have, extra upper button is an improvement, gps is slow locking the sattelites and when using gps with aprs would like to have the channel transmiting location even when not selected (blue background) en the screen... what else?? well thats for now

The Encryption DMR feature is interesting for sure. Maybe in Canada you can use it, but unfortunately here in the USA its illegal to use under FCC regulations to use :( (although it would make a great emergency use radio for SHTF)

[ZiggleFingers]

for the bluetooth mic to trigger vox it would have to keep the bluetooth audio channel open which would kill both devices batteries. you would need a bluetooth push to talk button which are available fairly inexpensively. the earpiece that it came with probably has a ptt on it.

At this point I have 7 different hand helds, but you almost convince me I need one more✋73's🎙KD9OAM🎧

11:04 Bandwidth 12, 5 kHz on PMR band it's twice as wide. Transmitting with a deviation of 10 kHz is interfering with 2 adjacent channels. Can this radio be set to receive and transmit 6.25 kHz bandwidth?

[BobBob-ilku]

This is one of the best choices for a Prepper/MAG group IMHO

Anolog/DMR(digital)
Ip67
Text message SMS
USB-C
TRI band uhf/vhf 220 (136-174MHz 222MHz-225MHz 400-520MHz)
AES-256 encryption
Front panel programmable
Proper multpin waterproof accessory/speaker mic port. (Motorola m3)

[EHOQ]

The screen is slightly bigger it would be interesting what firmware will bring later in future

[SebastienPons-exqu]

Bonjour je viens d acquérir le hd2 donc pas encore le diplome de radio amateur (débutant). allez vous faire prochainement une video sur le hd2 en français sur la programmation des radio amateur et pmr 446 sur le hd2 merci pour vos video très intéressantes

[sekibulja-fubv]

Another great video, thank you! Do these Hd1 and Hd2 have fast frequency copy button like most Baofeng radios?

[anthon]

I have noticed some reports of spurious emissions. Do you have some further insides on that?

[hbr.pierre-]

Bonjour je suis tout nouveau dans la radio je viens de me prendre uvk5 8 quelle firmware tu recommende pour du preper, il y a le tout nouveau v03 de f4hwn qui a l'air vraiment bien mais ji connais rien 😅

[senpayt]

is it actually in ailunce hd2 aes256? does it let you write all 256bits? or does it pad after 64 zeros?

[wakatepoo]

Hello Gilles,
Unfortunately impossible for me to show time/ hour on the second channel. Is there any specific manipulation to do ? Thank you !

[paullisi]

How do you get the vox working with tht bluetooth headphnes. What headphones are they.

[williamforest]

Il y a des versions virtuelles de Windows OS qui peuvent être opéré sur MAC OS. Pas un adepte d'Apple, mais plusieurs utilisent ce moyen d'éviter d'acheter un Windows

[geraldcampbell]

There have been Bluetooth equipped radios for years my AnyTone 878 and my Icom ic52 both have Bluetooth that’s nothing new!
