Retevis RT-B6

You never know where these things will show up... I was helping with a class and noticed a radio sitting on the counter.

The labels on the radio and the charger don't match. I turned it on for a quick picture and then popped the battery off.

I want to see if there are others scattered around the building. If I had to guess, someone bought something like this 10 pack for emergency communications. I'm betting they think they just bought some walkie-talkies.

I can't recall if I've seen this before, but a pointer in the comments has it back to the top. The image is from the BaofengTech website.

Baofeng UV-B5: Flashlight Mod

You know I like opening radios up for no apparent reason. This UV-B5 was especially attractive to me - look two rotary encoders with that easily breakable blue plastic!

But that's not the point...

See, this enterprising soul has discovered that you can add a flashlight to the UV-B5:
"Just underneath where the rotary knob is the two holes for the flashlight L.E.D. on the UV-B6 model. 
Even though the circuit board is printed UV-B5; I assume that both radio's have the same circuit boards? 
It also look like the switching transistor for the L.E.D. next to it. I wonder if you put an led in here whether it would light up? If so maybe a backlight mod can be done as the button under the monitor IS wired in circuit (On the B5). I take it that the flashlight on the UV-B6 is either ON or OFF and doesn't flash? if so then this has given me food for thought!"
"Just temporarily put an L.E.D. in the holes and it works! So a mod can be done to have a UV-B5 with a flashlight!! All the components ARE already in circuit on the PCB."

Now some may ask "Why?" when you could get a UV-B6. To them I say, why not? Also, you could have both a flash light and knob for changing channels.

Baofeng UV-B5: Best Kept Secret

[ Don't have a UV-B5 yet? Get one here. ]

Ben (PA2OLD) called me out for being so slow to post about the Baofeng UV-B5. Hans posted some general information about it when he discovered the UV-B5 and UV-B6. (Yes, back in November - just wait, it gets worse.)

On the surface, it is your typical dual band 5W Chinese HT: 136 - 174 MHz and 400 - 470 MHz along with 65 - 108 MHz FM receive. Here are the links to the radios on the Baofeng site: UV-B5 and UV-B6. Of note is the lack of the customary flashlight (for the UV-B5) and, perhaps more importantly, 2.5Khz steps. You can get one at the 409Shop for $53 (USD) along with many of the usual accessories (USB programming cable, serial programming cable, extra batteries or chargers) - no colors or AA/AAA battery packs yet. Give them time and I am sure they will show up. As you will find, the UV-B5 does not share the same form as the UV-5R, so you won't be able to share batteries or chargers. However, the programming cable from your UV-5R should work.

No surprise.. a Yahoo Group has been started for the UV-B5.

Hans, in his full review, says:
"For now this is the HT to compare others with – the receiver is at least as good as the Wouxun KG-UVD1P and outperforms the Quansheng TG-UV2. Overloading is not impossible, but far from easy – almost unreal for an HT this price."
"The Baofeng UV-B5 is close to perfect. The only two niggles are the 5-character limit for alphanumeric descriptions and the belt clip screws which are too short. For the rest: best value for money to date. Needless to say, I’m keeping this one."
Hans also points out that you can save a few dollars if you don't want the pretty box by ordering from AliExpress. I'm guessing price was not the biggest factor when Hans did his "Best/Worst of 2012" and ranked the Wouxun KG-UVD1P ahead of the Baofeng UV-B5. If price had been weighted heavily it looks like the UV-B5 might have been the winner.

Lastly, after living with the radio for a while he found some problems with the FM tuning and memories. He also reports the battery life, while not horrible, isn't great.

And Ben got his hands on one. He's got a summary page here with lots of pictures. He comments:
"The radio works excellent and the modulation is also good, not like some UV-5R types.I also think that the battery is more than enough capacity.
This Baofeng UV B5 cost at the 409shop only 53 Dollar, which is in Euros (with the exchange rate of January 2013) € 41.75 including shipping."
Bob (K0NR) really likes it as well:
"My overall assessment is that Baofeng has cleaned up the issues with the UV-5R (and don’t forget, I really like that radio!). The UV-B5 is a sweet little radio that will make a splash when it hits the US market."
Given my tardiness, the price, and the glowing reviews from the big name ham radio bloggers above, I'm surprised these things aren't the talk of the internet. The Yahoo group is of a modest size and Google searches don't reveal much beyond the links above. (I found one other review, but there wasn't much meat to it.) Here is the best video I found. (Best meaning the better of two.)

So for now, I'm calling the UV-B5 the best kept secret in the world of Chinese radios!
