Chinese DMR Radios

There are more and more digital standards popping up and with that, more and more radios but the Motorola and Hytera radios can be expensive for someone wanting to just dabble in DMR. So what alternatives are there? I've done some browsing on eBay to see what the Chinese manufacturers are offering someone who wants to try DMR.

Top 5:

The following 5 radios look to be the best of what the Chinese manufacturers have to offer at the moment. I've listed them below for comparison. More info can be found by looking on Google or eBay for these. Prices are correct as of 24th March 2015.

Beifeng TD-501

This radio is MOTOTRBO compatible and also analogue and is approximately £190 shipped.

Frequency rRange: 400-470 MHz

1 x Hand Strap
1 x User Manual
1 x Adapter
1 x Desktop Charger ( 100V ~ 240V ) 
1 x Free programming cable

Connect Systems CS700

This radio is MOTOTRBO compatible and is approximately £170-£200 shipped.

Unlike the TD-501 this radio has a CTCSS board and GPS built in as well as being MOTOTRBO compatible. It costs around £200 shipped.

136-174 MHz
350-390 MHz
400-470 MHz
450-520 MHz

Channels: 160

Quantun QP2100

This radio is MOTOTRBO compatible. The sellers claim they are made by Hytera but Quantun have their own website for these so I doubt this is true. They cost around £170-£190 delivered.

Frequency Range: 400-470 MHz UHF / 136-174 MHz VHF
Channels: 1000

KiriSun DP770

One of the earlier manufacturers of Chinese DMR radios, Kirisun has received some great reviews about this radio. It comes with GPS and is MOTOTRBO compatible. It costs around £260 delivered.

Frequency Range: 400-470 MHz
Channels: 1024

Bargain Basement:

If you want to try DMR at its lowest price then the following radios are probably the lowest priced units around. I don't know how well they work so Google search for more info.

QYT D-68

This radio is MOTOTRBO compatible and costs around £99 delivered. A great radio to try if you're just testing the water with DMR.

Frequency Range: 400-480 MHz
Channels: 32


This radio seems almost identical to the one above. It costs around £100 delivered.

Frequency Range: 400-480 MHz
Channels: 32

TYT MD-280

Again, almost identical to the one above this Tytera has some pretty good reviews for the price. It costs around £125 delivered.

Frequency Range: 400-480 MHz
Channels: 32

I hope you found the information above of some use when deciding what DMR radio to try.

Thanks for reading!

I scout eBay regularly looking for new radios appearing from the far east for all the weird and wonderful creations that keep popping up. I came across the TYT (Tytera) TC-3000A tonight and it looks like a nice little radio. It claims to boast 10w output power on UHF among other features:

10W/5W power switch with side-key operation.
10 Watt ultra-high output power.
Computer programmable.
Voice companding function.
Bandwidth select (12.5/25kHz).
Battery save function.
1750Hz tone.
Squelch adjustment function.
End-tone elimination.
Receiving alarm.
Side-key assignment.
Low-battery alert.
Busy channel lock.


Total Length: Approx: 1m (I hope not??).
Weight: 40g (Again, hope not!).

1x Polymer Li-ion Battery Pack.

Baofeng UV-5RA

I've always liked the look of the Baofeng UV-5R cosmetic variants such as the UV-5RA, UV-5RB, UV-5RV2+, UV-5RE, UV-5RAX+, UV-5R PLUS etc. So I decided to get a UV-5RA in yellow. The yellow looks really good and reminds me of those marine radios that come in the same colour.

There's not much to report on this radio really, it is just a UV-5R inside but looks much better. The original UV-5R is a great radio and so it this UV-5RA. It features the second generation board, flash light and high power is around 4w but at £22 delivered it's a bargain.

Basic features are as follows:

  • Frequency Range: 136-174 / 400-520MHz
  • Dual-Band Display, Dual-Standby
  • Output Power: 4 /1Watts
  • 128 Channels 
  • 50 CTCSS and 104 CDCSS
  • Built-in VOX Function
  • 1750Hz Burst Tone
  • FM Radio (65.0MHz-108.0MHz)
  • LED Flashlight
  • Large LCD Display
  • Emergency Alert
  • Battery Saver
  • Time-out Timer
  • Keypad Lock
  • Channel Step: 2.5/5/6.25/10/12.5/25KHz.

Back to basics for me on this radio but I forgot just how good the Baofeng UV-5R is for the money it costs!

Thanks for reading!

Baofeng UV-5X: UV-5R Re-Clothed?

I've been looking into Baofengs latest release, the UV-5X and seeing if it's really worth getting. It is nicely styled and meant to be an updated version of the UV-5R. After reading the specs I can't help but think this is just a UV-5R or GT-3 in a new case yet again.

It doesn't appear to have any new features whatsoever on the technical side. Dual watch feature seems to be heavily advertised but the GT-3 has it. The shell is different and I'm not sure I like the VFO/MR and A/B buttons positioned sideways at all. It doesn't even seem to feature the extra higher power option of 8 watts.

Another new 'feature' is the suggestion that the radio is waterproof. Let me assure you this is not the case at all. Water can slip between the battery and the radio and in all other gaps on the radio. It may be shower/mist proof but definitely not waterproof as you'll see another radio amateur found out in a video I'll include at the end of this post.

He completely submerses the radio in water and it dies instantly. I know there is a difference between waterproof and submersible but I can imagine it'd be easy for some people to mistake the two and try submersing their radio in water assuming it'll be ok. There is no sign of a rubber gasket to seal the radio like on some of the submersible handhelds on the market and water will get inside through the speaker, microphone and the screen.

Lastly the radio is supposed to be resistant to extreme pressure. The radio can sustain being run over by a car tyre but so can the UV-5R. This is due to being such a small product with a hard plastic casing that is filled to the rafters with components that help spread weight evenly over the radio. Secondly, most of the weight of the car is supported by the other 3 tyres so it is not surprising that it will survive being run over however I wouldn't recommend.

So all in all nothing really new here from Baofeng.
