Baofeng UV-3R Review

Following the success of the Wouxun radios, we have a new Chinese handheld transceiver that has many hams excited – the Baofeng UV-3R. The UV-3R is a dual band (UHF/VHF) 2W “micro” transceiver manufactured by Vero Global Telecom and sold by Baofeng. While the Baofeng brand is the most popular, the radio is also sold as the Comtex UV-3R, the Magiksu UV-3R, and the Zastone ZT-UV3R. (Baofeng also sells the UV-100 and UV-200 models that share common internals with the UV-3R, but have some cosmetic differences. Also, on you can find speaker mics for these models that are unavailable for the UV-3R.) One reason the UV-3R is so popular is its relatively low price – less than $50 via ebay and slightly more from the US suppliers. At this price and small form factor, it makes a great back-up radio to keep in a truck glove box or a laptop bag.

Cosmetically, the UV-3R is very similar to the Yaesu VX-3R.


The dimensions are the same, but the UV-3R is missing a few buttons on the front panel and the functions of the duplicate buttons are not the same as the VX-3R.  The UV-3R, in the fine tradition of Chinese radios, adds an LED flashlight. The radio also is available in red, yellow, blue, and camouflage in addition to the standard black. When holding both the Yaesu and Baofeng in my hand, it is easy to see and feel the superior quality of the Japanese radio.

A quick review of the technical specifications reveals that this radio is dramatically different from the VX-3R. The UV-3R is a 2M/440 MHz transceiver and FM broadcast receiver. An abbreviated list of its features/functions/specs is below. (A full list can be found here.) The radio is built by levering the power of the RDA1846 by RDA Microelectronics. This single transceiver chip provides most of the radio functionality – essentially making it a SDR.

Early adopters were “treated” to a version that appeared to be rushed to market – the units only had twelve menu options, the s-meter was worthless, and it came in a rather plain box. The subsequent version added six more menu options, improved the signal meter, and now comes in a more polished box.

The menu options are:

In addition to the cost and size, hams give the UV-3R favorable reports for both transmitted and received audio. On July 20, 2011, the UV-3R became Type 90 accepted by the FCC. The FCC documents can be found here.

The UV-3R is easy to use in spite of a somewhat confusing manual. ZL2GVA mitigated that short-coming by releasing an easy to use cheat-sheet.  While most folks find it easy to program the memories from the radio itself, the UV-3R can be programmed from a computer using a USB cable and software from Baofeng. In addition to the factory software, the UV-3R is also supported by the CHIRP cross radio programming application. (CHRIP may not program all features for all radios; it is intended to allow hams to transfer memories from one device to another with little effort.)

In addition to the USB programming cable, the radio has several accessories. It comes with the manual, charger, a charger adaptor (if needed), a charging stand, wrist strap, an UHF antenna, a VHF antenna, an ear bud/mic combo, and a belt clip. The shorter antenna (with a red ring) is for UHF. The longer antenna is for VHF. The UV-3R requires an antenna with a SMA-M connector. The antennas perform well, but many folks have wished for a dual band antenna. The Nagoya NA-701 and Nagoya NA-666 both seem to be popular choices. The antenna connector is fairly close to the LED, so some trimming may have to be done to get a good fit.

Car chargers, cases, and the USB programming cable are available as options or sometimes included as a bundle with the radio. The battery is a common NP-60 (FUJI compatible), so picking up an extra one is easy to do. Also, with a slight modification to account for the belt clip mount, the AA battery pack (FBA-37) for the Yaesu VX-3R can be used to run the UV-3R. For me, the car charger and the AA battery pack are the must have accessories for the UV-3R in its role as a backup radio.

The radio is not without some minor problems and quirks. For example, one oddity is that it uses the less common negative tip for the power plug. As for the problems, hams have reported issues with fit and finish – specifically plugs/sockets that result in loose connections. If pushing the plug with all your might doesn’t work, then try backing it out a little. Also, hams have found spurious emissions on harmonic frequencies.  There was a lot of debate about the severity of this issue on the UV-3R Yahoo group – bench vs. real world, letter vs. spirit of the FCC regulations, Type 90 Acceptance impact, etc. Whatever the severity of the emissions, it did not prevent the UV-3R from meeting the requirements of the FCC. Another common complaint was with the loud receive volume. Even at the lowest setting, the radio is quite loud. For that reason, I don’t like using it where it will bother others.

One of the advantages of an inexpensive radio is that you don’t risk much when trying to modify it. Disassembly mostly involves removing screws, but you will have to unsolder the antenna connector. Two mods seem to be the most common as they address some of the issues mentioned above. The first adds a capacitor to reduce spurious emissions on the harmonics.  The second also involves adding a capacitor to reduce the loud receive volume issue.  More frivolous mods include turning the LCD blue – but then you can have a blue radio with a blue screen.

For me, this little radio has provided a great learning experience as well as a good value for my money. It may not be the best radio ever, but the price, size, and overall good performance make it a good choice for backup radio or even one for a new ham to get on the air. It also has been interesting to see:

  • the debates that sprung up around the severity of the spurious emissions,
  • the wisdom (or not) of using a dual band antenna,
  • the variety of applications from simple transceiver to APRS and tracking satellites

Credit goes to a lot of the guys on the UV-3R Yahoo group  – I don’t have the knowledge, tools, or time to do a lot of the research/testing/playing that they have done. I highly recommend the Yahoo group – although it has now reached a point where a lot of the same questions are being asked.

    Good article.

    “The second also involves adding a capacitor to reduce the loud receive volume issue.”

    should read:

    “The second also involves changing a resistor to reduce the loud receive volume issue.”

  • Paul Ross W3FIS:

    New version from comes with a dual band antenna. However, I get MUCH better performance with a “no name” SMA wire whip. The Diamond SMA antenna works fine as well, but it is a little bulky. Volume level on mine seems fine.

    Use one of the RG-174 adapter cables from Universal Radio or others to make a connection from the UV-3R to any external antenna, such as a “J” pole.

    You don’t need a speaker microphone! The UV-3R is about the size of a decent speaker mic.

    The November (most likely) K9YA “Telegraph” should contain my take on the Baofeng UV-3R.

  • George wb9sjz:

    I like this little radio, but I have noticed that while listening to the person that you are in conversation with, sometimes the speaker will drop for a miniscule second and then be back to full listening of the person you are in conversation with. If anyone has also had this problem and can let me know a ‘fix’ for it, please let me know.

  • Rob AA1UY:

    Looks good, but they need to add a means of utilizing the DTMF capabilities that the chip it’s built around has available.

    Although the Yaesu VX-3R doesn’t have a DTMF keypad, you can generate DTMF tones via the menus from what I remember.

  • Tom WH6PH:

    These little radios do look attrative with their much cheaper price than the Yaesu’s or the Icom’s, but I do wonder about the quality, I am not a big fan of electrical items made in China as their quality control has much to be desired ! I do wish an American company would produce a quality full coverage 2 meter/440 FM handheld, and I’d love to see a handheld with SSB as well as FM !

  • G0VZ:

    This site also has some useful information………


  • Bojan 9a7NAD:

    Just ordered my baofeng a few days ago. It seems to be good value for this money.
    does anyone know if the RX range can be extended?

  • Brick O'Lore:

    @Bojan – some people have had some luck with expanding the frequencies, but it depends on the version of the UV-3R:

  • Mike N7MSD:

    I checked out the link to the RDA1846 you provided, and while there checked out its cousins the 1845 and 1847: the RDA-1847 is particularly interesting because it is designed for DMR (aka MotoTrbo, and what the FT-1D is targeted at); I’m guessing it may be able to spit out D-STAR as well, but I never found the real data sheet.

  • Dave angell, G0BHS:

    The UV3R is a fine little radio for the price, and I have at last worked out how the memory scan works. Now it is very easy to scan the channels, and either select to have it lock onto one or to slowly pass by them until I find one of interest, where one can stop the scan. The Wide setting is much better than the narrow on these little microtranceivers.
