Baofeng UV-B5 and UV-B6 Review

Two new radios from Baofeng have just arrived today, the UV-B5 and the UV-B6.

Baofeng UV-B5(left) and UV-B6 (right) 

Both radios sell on the Internet for less than $50 U.S. and have similar features such as 99 channel programmable, UHF/VHF, dual watch with 5 watts of transmit power.  Both units received an excellent audio quality report when I tested them on a couple of local repeaters.

Baofeng UV-B6 with LED Flashlight

The slight differences between the two radios can almost immediately be spotted.
The UV-B5 has a channel select knob at the top of the radio where the UV-B6 has an LED flashlight.  The radio must be on to use the flashlight.  

The UV-B5 has an red alarm button just below the antenna where the UV-B6 has none.  The instructions on the B6 claims to have the button on the microphone/earpiece/programming jack but we have not found it yet.
Both radios use the same USB Prolific programming cable as the Baofeng UV-5R series as well as any microphone / head set systems.  The programming software is unique, which can be downloaded from the Baofeng website:

Chirp software has a daily build for the UV-B5 & UV-B6:

The Belt Clip on both radios have extra firm springs.   The chance of losing this radio from your belt or vest is slight as it has a very strong grip.

One very cool feature about this radio is the volume knob.   When you turn on the radio the volume knob appears to stick around the first quarter of the volume control.   I thought that this was a defect on the first radio until I noticed the same thing with the second radio.   I think it is intentional.  When you turn on the radio and set it for a desired volume around the first quarter turn of the knob there is less of a chance of that being identically turned down to zero should the radio be attached to your belt or vest and you brush up on something.  For someone using this radio with a headset in a security job setting this could prove a valuable feature.

LED read out on both radios is not as big as the UV-5R series but it is legible.  You can also turn off the back light on the LED to conserve battery.

The Battery on the radios charge up in about 5 hours, according to the manual.  The charger cradle has an LED that will turn green when it is fully charged.

The important thing to know about these radios is that you should not allow your hand to make contact with the battery charging terminals on the back of the radio while you are transmitting.   I noticed that they tend to generate some heat, which could result in a mild burn.   It may have been the humidity adding to the factor here in Long Beach when noticed this.

It's all Chinese to me!!

Programming the radio with the Baofeng software is pain free except when you load the software in from the site it is defaulted to Chinese.   When you run this software for the first time it literally is all Chinese to you.
To switch to English simply press ALT S to get to the Settings Menu. then  L, select English with your mouse and hit Enter.   

Switching the software to English

You can also use mouse controls by selecting the second pull down menu from the right (or second to the last menu) and selected the bottom option on the menu.

There is also a red short cut on the menu to switch languages.

All in all, both radio are super, easy to use and put out a great signal.  They will remind you of another popular radio that comes from China.   The only thing I really did not like about these radios is that they took about 4 weeks to get here from China.   Best have patience if you order this from a vendor overseas or pay a little extra and get one sooner from a US vendor who might stock these.

I still prefer the Baofeng UV-5R series but will keep these radios in the to go bag for back up.

  1. >I still prefer the Baofeng UV-5R series
    Could you compare UV-B6 and UV-5R, please?

  2. Thank you for your suggestion. I will try to get a comparison up in a couple of days.
    Basically, the UV-5R series has less range, a wider variety of accessories available and a better LED read out.

  3. I just purchased the UV-B6 over the 5R because its an updated model but I do like the UV-5R look better than the B6. The 5R has a better look to it and doesn't look as cheap.

  4. I agree with Mike F. The battery compartment latch on the B5 and B6 are kind of cheap and overall appearance looks delicate. I have dropped my B5 and B6 a few times and nothing has broken yet. The good news is if it does it is only another $42 and about 4 weeks to replace it.


  5. I have both UV-5R+ and UV-B6, UV-5R has better look, better LED color, but I prefer UV-B6 because of the curve, I have better grip with that. UV-B6 also has better receiver and better stock antenna, I use nagoya RH701 with my UV-5R, but UV-B6 stock antenna is better than that RH701, so I have to buy UV-b5/6 stock antenna for my 5R.

  6. what about the Step Frequency(5,6.25,10,12.5,20,25KHz) is there a 2.5 option or not ?

  7. I have the UV-B5 that I purchased after seeing reviews on here and other sites. I am using this as my primary communication with our fire department when out on calls (non-firefighting calls). The issue I am having is, I can hear everything clearly over all of the channels, and it works perfectly during line of sight communication, but when I am outside of a certain range, transmitting is not occurring. I can still receive at all distances (10 miles to any repeater and very flat land) but transmission is only occurring when I am near anyone I am communicating with. Transmission anything >2-3 miles is non-existent.

    Any ideas what this may be from, or I need to change anything in the software for programming?


    1. Scott McKnight... Hopefully you've found an answer elsewhere by now. It sounds like you haven't set a repeater off-set. I think you are transmitting and receiving on the repeater output frequency. You need to set an offset so you transmit on the repeater's input frequency. Check with others in your repeater group for specifics.

  8. Wow. Baofeng has come a long way from the days when I bought that old UV-3R. The front end on the UV-3R worked too well. Seemed like every signal in the area was breaking the squelch. Recently bought my Baofeng UV-5R Plus stuff over at and was really satisfied with the radio, price and delivery time. Use the latest build from CHIRP and you are on your way... Forget that poor excuse for software from the Chinese.

  9. Sorry, but the UV-82 kills them all, hands down, and for nearly the same price. It feels better (larger size, larger keys, a little heavier, more professional), performs better, is more rugged, and has two built-in radios (complete with two PTT buttons.) The menuing of the B5 and B6 are the same, and they don't make a whole lotta sense. The menuing of the 82 resembles that of the 5RA and is easy to navigate. Like the B6, however, switching between channel and frequency mode on the 82 is awkward.

  10. Thanks for the tip Noji. I will order one soon and check it out.

  12. Hello. First of all thank you very much for sharing your experiences with the community .
    I 'm looking for an economical dual band radio and in my country ( Argentina ), the Baofeng UV -B5 , the Wouxun KG- UV899 and Wouxun KG- UVD6P have similar prices.
    I would be very useful recommendation on that team performs better , especially in RX. Thank you for your time and sorry if my English is poor. 73's

  13. Hi RinconV.
    For the best bang for the buck (investment) the Baofeng UV-82 has to be the finest radio around.

    Your English is perfecto mundo!
