Baofeng UV-3R: Guest Post/Review at AmateurRadio.com

Matt, over at AmateurRadio.com, asked me to do a guest post at his site. The following UV-3R review first appeared there on September 2, 2011. AmateurRadio.com has been a great resource for me - leading me to the likes of Julian and others - check it out.

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 ebay.com 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:

16	SCANM	Scan Memory	TO Time based – time out/ CO Carrier (present) based – carrier out
17	RELAYM	Relay Message
18	BCLO	Busy Channel Lock	Off/On (No Tx when receiving)

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 resistor 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.

Baofeng UV-3R: Second Harmonic Issue

December's QST has a Technical Correspondence (Boafeng UV-3R 2M/70cm Handheld Transceiver) article about the second harmonic issue in the Baofeng UV-3R. Bob Allison, WB1GCM (ARRL Lab Test Engineer), used an HP-8563E spectrum analyzer to determine if the radio meets the standards of FCC Part 97 for spurious transmissions. Bob finds that the radio (two units tested) failed to meet the standards and that "to legally transmit with these radios in the 2 m band, you would have to add a second harmonic low-pass filter at the antenna jack."

First, if you don't understand the basics of a spurious transmission on the harmonic, Steve (K9DCI) provides a good analogy on the of UV-3R Yahoo Group discussion on this topic:

"Spurious signals are more like driving with a 10 foot long beam sticking out the side of the car. As long as you drive on desert roads, you can relax because you "probably" won't whack any hitchhikers in the back of the head."

Some time ago, I had noted the spurious emission problem and posted a link to the mod to fix it on my UV-3R page. And I had thought the issue might have been fixed in newly manufactured radios, since the UV-3R had gotten FCC Type 90 Acceptance. For a major information dump on the topic, I would start with this UV-3R Yahoo Group post - also from Steve (K9DCI). Grant, ZL2BK, documents the magnitude of the problem at various frequencies. Basically, the filtering is better as frequency increases.

It is the issue that will not die on the UV-3R Yahoo Group:

• The original discussion
• The new discussion prompted by the QST article
• And the Mark II?
• And the Mark II again
• How big of an issue is this really?

As you can see in the above links, it does not appear that the issue was resolved in the Mark II. Some speculate that it is a quality control issue, but I am more inclined to think it is a limitation built into the design/components of the UV-3R. G4TUP suggests that Vero Telecom (and the various resellers) do not care as they designed the radio for the commercial market and, at the higher frequencies, it works within the standards. To keep the waters muddied, Bob (GM4CID) reports that Vero Telecom claims to have fixed the issue. And Andy (G0FTD) found that hisYaesu VX7R is worse than an unmodded UV-3R.

Here is the link to the low-pass filter mod that shows you how to add a 0805 size 33pF capacitor to reduce the emissions on the second harmonic.

Oh, and because I am apparently a sadist, here is a follow-up link where the same mod was performed and the results were less successful.

Baofeng UV-3R: Software

[ Don't have a UV-3R yet? Get one here. ]

UPDATE 11-12-12: A new version (1.10) has been released under the UV-X4 model. It adds the ability to update the FM Broadcast memories via the software. 

UPDATE 11-10-25: There is now an updated version of the UV-3R software that was released with the UV-3R Mark II - The new software information is *** here ***. 

UPDATE 11-09-27: As an alternative to the UV-3R software, you may want to try CHIRP. It supports the UV-3R as well as radios from ICOM, Yaesu, etc.

I've encountered two versions of the software for the UV-3R (Amazon). The first version, matching the screen shots below, has the installation steps in Chinese. This version is the one that came on the CD which shipped with my radio. I assume it is Chinese as my computer does not recognize the characters and displays gibberish. In this version the actual software is in English. The other version was the opposite - English installation with a Chinese application. As you can imagine, I stuck with the first version.

I installed the programming software first and assumed I would install the USB driver when I plugged in the radio. You can see the Chinese install below. The middle button in the first three screen shots is the one you want - you can tell by by the "N" that it is the "Next" button. The final window has an option to "C" for "Close" (not shown).







After it finishes installing, you get a folder with the short-cut to start the software.



I then plugged in the USB cable and the radio. When I powered on the radio, Windows detected the new device and started installing it. (Note: I did not do anything to put the radio into programming mode. Some rigs require that, but not the UV-3R.)I must already had the drivers for the Prolific USB to Serial chipset installed as it did not prompt me for any files. When it completed, it told me that the device was ready on COM5.


Next I started the software using the short-cut displayed at the end of the software install. First, I went to the Com Port menu and selected Port to display the Communication Port screen. I selected COM5 to match the information provided when the driver was installed.



I then clicked Device and Read to copy the configuration to the software. I saved the file before making my edits.



Once you've completed your edits, you will want to save the file and then select Device and Write. I recommend saving different versions of the file (perhaps by date), so you can always go back if you break something.

Baofeng UV-3R: Expanded Frequencies 222 MHz

Pat (WA6MHZ) expanded the capability of his UV-3R to include 222 MHz. His results:

Upon measuring the Power Output of the UV-3R+Pus on 223.5, I find the power is greatly reduced, On 2M and 440, I see +33dBM, which is 2W. On 223.5, I only get +12.26dBM, which is pretty lame. That come out to be 0.0168267406W, or roughly 16mW. So there must be some Filters messing with us. But I can hear it in my Kenwood TM-331A mobile rig just fine, so for short simplex it will work. Also to some repeaters where U have a good shot at it. The stock antenna is optimized for 2M & 450 so I need to score a Triband antenna so I have a chance of getting out with the 16 Milliwatts.

RX sensitivity is pretty good. Measured at -119dBM minimum discernable signal.

Measured TX frequency (223.5) 223.4988120 Mhz

So it WORKS on 222, KINDA!

In a follow-up post is a link to an app that will auto-mod your .ini file to open the frequencies. He has successfully used the program with a UV-3R Mark II and a UV-3R + Plus. Head on over to Mark's (VE3PZR) page and check it out.

Instructions:

How to update your UV-3R Mark II to support 220mhz Ham Band

 Some models of the radio are able to support a much broader range of frequencies if you store a special memory file into the radio.

Follow these steps:

[1] Install UV-X4 programming software

[2] Run the UV-3R-soft-Modder program to update your UX-X4 software to add some extended Band Plans

[3] If you have an existing memory file, re-run the soft-mod program to change the Band Plan that is embedded inside the .3R memory file.

[4] Load the memory file inside UV-X4 and write the memories to your radio and your radio will now have 220mhz added to your radio!

Tech TIP #1: If you are unable to write a memory file to your radio, power-on while holding down the VOL button. It will reset your radio back to factory and you will be able to write the extended frequency file.

Tech Tip #2: 2 memory files are included. Both files have 220mhz included but during tests with other hams, we found that my radio gave better 220mhz results if we lowered the UHF instead of raising the VHF frequency range. I suggest testing both methods with your radio to verify results.

KYD NC-5H, KYD UV-5H

Kenivore found "another UV-3R clone with more button[s]". At first glance, they look more like the Yaesu VX-3R than the Baofeng UV-3R, because of the extra buttons. The specs for the NC-5H and UV-5H are identical and very similar to the UV-3R. I did a quick search on eBay and could not find any for sale. A search on Alibaba has them for sale for $60 from New Century Communication and Electronics Co., Ltd. The company website is here.

In fact, the physical layout of the buttons on the KYD models is identical to the Yaesu VX-3R. For example, the power button is on the side like the VX-3R, but different from the UV-3R. Most reviewers are pleased with simplicity of the UV-3R menus using the limited buttons and knob to do the programming. Looking at the picture, it appears some of the menu items have gotten a dedicated menu in this radio. For example, STEP (MENU 9 on the UV-3R) has its own button. It does not appear to have a flashlight, but does have an inner and outer knob. Also, the web pages say they will support the channel naming via a programmable alpha-numeric display. The NC-5H does not explicitly say that it is a dual band, but the specs have both 2M and 440 listed.

Yaesu VX-3R Knock-off: The Baofeng UV-3R

The Chinese are at it again. This time we have a knock-off of the Yaesu VX-3R. The VX-3R is a tiny, but full featured 2M/440 HT. At $175, it isn't super expensive, but not exactly cheap either.

Enter the Baofeng UV-3R... it looks a lot like my VX-3R, but you can get three of the UV-3R for the price of the Yaesu.




G4ILO is on top of things again with a great review of this new rig. Some of his key points follow:

"The UV-3R makes [another Chinese radio] look a quality product. This is the first new electronic product I've had that didn't come with a peel-off protective film over the display. The plastic casing is extremely thin and the plastic belt clip that can optionally be attached looks as if it would easily break. To be fair, the flimsiness of the Baofeng may not be due to cheapness but to save weight."

"Confusingly, the rotary switch on top of the radio must be pulled up before it can be rotated."

Note: the VX-3R works this way as well.

"I also checked the strong signal handling performance of the receiver the same way I did recently with my other hand-held transceivers. It was on a par with the VX-8GR and the JMT-227, at the poor end of the spectrum."

Here you can see the UV-3R in all its glory.



For $55 I am willing to roll the dice. When the storms hit last week, my wife was looking for my VX-3R. Unfortunately, I keep that one in my laptop bag. I was contemplating another radio already, so finding this one has tipped the scales. I'm off to eBay.

Chinese Radios - The Center?

The Baofeng UV-3R is a re-branded Vero Telecom UV-3R.

The Vero Telecom VR-2200 is a re-branded TYT TH-9000.

The Baofeng UV-5R (which I cannot find on the Baofeng site) is similar to the TYT TH-F8.

When the UV-3R came out, I thought VeroTelecom was going to be the actual manufacturer - if not the design house, too. The UV-3R was availible as a Baofeng UV-3R, Magiksun UV-3R, Comtex UV-3R, and a Zastone ZT-UV3R. Vero Telecom was going to be the source.

Now it appears that the VR-2200 is actually a TYT TH-9000. And the UV-5R looks like it has it origins in the TYT TH-F8.

Is TYT going to be the center of the ham radio world for China manufacturers?

Does ICOM buy Yaesu radios and re-brand them? Is Elecraft reselling Ten-Tec rigs? The game is different in China. Maybe they just like to keep us on our toes. I am going to need a map.

One Year of Brick O'Lore

One year ago today I started this blog with a post about Financial Commitment Sunday at my church. At the same time I was contemplating a purchase of some radios and guns. Well, I got some radios (IC-7000 and UV-3R), but I never did get the AR or the Glock. And now I've been leaning towards the M&P9.

When I was writing that entry, I was thinking that I would blog for a year and then see if I wanted to keep doing it. I plan on continuing the blog, but I feel less pressure now. I've had various undocumented goals - three posts a day, so many a week, etc. None of which I've consistently met. I blog when I feel like it - which is fairly frequently. I had envisioned longer, more thoughtful posts (like Linoge and others), but it turns out that I'm closer to being a linker. As far as the personality of my blog, it was going to be some guns, ham radio, technical, commentary on society, etc. It turns out I was going to post quite a bit about a little radio and the page views would go up dramatically.

As you will see in the stats below, some how this became a Baofeng UV-3R blog. It all started with a simple post about a Yaesu VX-3R knock-off.

As of late yesterday, the blog had 112,231 page views for its first year. I've made 856 posts in that time.

The single largest referring URL was Say Uncle - primarily for the Ninjas in my House post with 1,850 views.

However, the single most visited post is the Baofeng UV-3R software instructions at about 7,000 views.

The single most visited page is the Baofeng UV-3R summary at almost 11,500 view for the year

Google.com is the largest referring site at about 12,500 pointers to the blog. If I add in the referrals from Google in Germany (2,500), the UK (2,200), Italy (2,100), Netherlands (1,200), Spain (600), and Canada (400), then Google is responsible for 21,500 views. Most of the hits from Google are from searches for the UV-3R.

Feedburner tells me I have a few RSS subscribers. Google Analytics tell me that I have lots of people who get here by way of the Baofeng searches and they click through to another post between (roughly) 30% to 60% of the time depending on the particular starting page. People average 2.93 pages and 3.15 minutes per visit.

So, where do I go from here?

More of the same I suspect. The UV-3R has been a great learning experience for me - both as a ham radio and as a blogger. I've got too many interests and not enough time. I think you've see that here... radios, running, tablets, guns, prepping, computers, reading, etc. Toss in a wife and an almost three year old - time is my limiting factor for sure. The Radio Amateurs Code reminds hams that playing with the radio is a hobby and that the ham should be balanced - never letting it interfere with "duties owed family, job, school or community." I might add church to that, but it still sums up where I am.

Let's see what the next 365 days bring. Some goals... pass the Extra Class exam, keep running - maybe a marathon, earn a WAS award, pay off my student loan, finally pick up that plastic pistol, and blog a little.

Thanks for reading.

Baofeng UV-3R: Mark II Software

[ Don't have a UV-3R yet? Get one here. ] 

UPDATE 11-12-12: A new version (1.10) has been released under the UV-X4 model. It adds the ability to update the FM Broadcast memories via the software. 

With the release of the new Baofeng UV-3R Mark II, the original software has also been updated. (You still have the option of using CHIRP.) And, as usual, Julian is ahead of the curve with his post about the updated software.

To use the software, you will need a few obvious items - the UV-3R (Amazon), the free software, and a programming cable. Download the software here for version 1.09. You can order the programming cable or build one. If you don't have a radio, then you can order one here, there, and yonder.

Before walking through the install, here are some trouble-shooting tips to keep in mind.

• Make sure the first memory location is populated. It will cause errors if it is left blank.
• Always read from the radio first and save the file as backup. It is nice to have a known good config. This practice does assume you can read from the radio without writing first.
• As you may have gathered from the lines just above, sometimes you must write a file to the radio first. An example of this situation is when you get an NKT_3R.EXE Error Signature.
• Likewise, if you get both rows on the display showing DDD.D25 then try adding some frequencies via the software and write to the radio.
• Make sure your cable is good.
• Confirm in Device Manager that the USB driver installed correctly.
• Verify that the COM Port used by the USB device matches what you have configured in the software - see screen shots below.
• Set the baud rate to 1200 if you have inconsistent results using the software.

Also, you should note that the old software created ".dat" files. The new software creates ".3R" files. You cannot simply rename a ".dat" to ".3R". However, you can open the new ".3R" files in the old software.

The install process is fairly simple.

I plugged the USB cable into the radio and then into my computer. I turned on the radio and Windows 7 installed the Prolific appropriate driver. In this case, it is using COM8.

As I mentioned in the trouble-shooting, you may need to change the baud rate to 1200. Right-click the device and select Properties. You can change the baud rate (Bits per second) using the drop-down box.

Now that we know the USB driver is installed correctly and which port it is using, we can start installing the software. Double-click the file you downloaded (extracting it from the compressed file if needed - if you need something to open .RAR files, try 7-zip.) Click Next.

If you are okay with the default install location, click Next. Otherwise, use the Browse button to change the location.

Click next to use the default name for the Program Folder that will be visible under your Program Files.

Confirm your settings and click Next.

Once the file copies are complete, click Finish.

You get one more screen showing the version. Click OK to complete the install.

To launch the application, double-click the short-cut it created.

You can click Help then About to confirm the version you are running. If you've installed previous versions, this might be worth a couple of seconds to make sure you have launched the latest one.

Click Settings the Communication Port to make sure your configuration matches the COM Port the USB device is actually using and then you are off to the races!

And in a comment on an earlier post, Chris had already assured me that he will have the yellow version soon.

Baofeng UV-3R: Charging

If you open up the the supplied charging base, you will find that there is no circuity between the input and the battery. This has lead to much speculation about the wisdom of using the base to charge a battery outside the radio.

Grant, ZL2BK posted the following which appeared to be a definitive answer.

I did a bit of research [on]the battery and it is also used in a number of different products such as cell phones. It appears to have some protection in the battery to prevent overcharging as is common with these batteries (or single cell in this case).

I put my partially discharged battery on the charger and the charge current was 1.1 amp. The voltage across the terminals was 4.25 volts. I checked the current occasionally and it remained close to 1 amp until the voltage rose to almost 4.3 volts at which point it dropped to zero.
As there are only two terminals on the battery, there is no way of controlling an external charger so there has to be some electronics in the battery for safety and this quick test shows that.

I used the supplied wall supply for this quick check. The voltage on no load was 5.09 volts.

I was happy with that bit of detective work until Tom PA2TSL had to muddy the waters again.

I wonder why a charge circuit (with the LTC-4054-L IC) is present in the UV-3R
when it is already build inside the battery.

I can ony imagine an additional protection when a non-standard power supply is used to charge the battery when it is in the UV-3R.

Anyway, it is nice to have a spare battery available that can be charged outside the UV-3R.
I was about to build the same charge circuit in the cradle, but that makes no sense when it is already inside the battery.

Tom PA2TSL later adds:

It should be quite easy to reproduce the charge circuit and put it into the
cradle.

A few additional components are required when using the LTC-4054L that is used
in the UV-3R.

You can add a LED for the charge status (just connect it between the appropriate
pin of the IC and the supply voltage with a small resistor).

I guess I will assume that the battery is smart enough to prevent over charging (and fires!), but it would make me wary of buying a knock-off battery that might not have the built in brains.

Baofeng UV-3R: Expanded Frequencies

In addition to the old trick of opening up the ability to store alpha tags in the Baofeng UV-3R, Frank Fort notes in the comments that he's opened up the frequencies available to his radio via the software:

"Baofeng Uv-3r Mark 11 is now with a 115Mhz to 530Mhz TX and RX modification, with the modded program...

• Close the UV-3R Mark 11 software if you have it running.
•  Browse to folder where the software is installed. (The default is C:\Program Files\UV3R.)
•  Double-click the "setting.ini" file.
• I tried copy and paste but didn't worked for me so i just changed manually for this.

[setup]com=2searchcom=1name=1
language=english 

[ModelInfo]
Freq0=[136-174/400-470]
data0=6013401700400047

Freq1=[115-400/400-529]
data1=5011993900409952

• Close the file and save the changes.
• Run the UV-3R Mark 11 software.

The (Name) option will work in the program only,not on the Baofeng but you can take notes.

So now you have now 3 frequencies choices in the menu up left in the program window. Now that's fun...I have a Baofeng Mark 11 with 19 menu options and work very well..."

Anyone else try it and have any luck? I know with the Wouxon that you can open it up and receive, but that the radio isn't designed to transmit outside the original frequencies.

Baofeng UV-3R: Speaker Mic

I briefly mentioned it in the previous post, but NH7QH Radio Supplies, LLC has a speaker mic for sale that will work with the Baofeng UV-3R Mark II. The critical note is that it only works with the Mark II. If you read through the UV-3R Yahoo Group archives, you will see a) lots of people asking why you need a speaker mic for the UV-3R and eventually b) no one having an answer for one that works well with the original UV-3R.

Baofeng UV-3R: Battery & AA Battery Case 2

Today, I got the AA battery case that is based on the Yaesu FBA-37 and should fit the Baofeng UV-3R. I already had a Yaesu case, so I am comparing it to the cheap eBay version. I hate to give away the surprise, but you get what you pay for... The $21 FBA-37 is clearly better made than the $10 eBay version.

The eBay case (right) had a film all over it. It wiped off easily, but it looked like it came from a dirty plant.


The Yaesu (left) is much better engineered. On the eBay case (right), the metal strips that run between the contacts are just roughly covered with some plastic tape.


Here is the eBay case on my VX-3R. It is hard to tell in the photo, but there is a gap along the side where it does not fit well. I think the batteries do not sit flush against the base of the case and this keeps it from close snugly.


As usual, once I get the actual Baofeng UV-3R, I will update when I try this case on it.

Baofeng UV-3R: Battery & AA Battery Case

Alternate Batteries
The UV-3R comes standard with a 1500 mAh battery with a stated run time of 10 hours. There are reports that this a common camera battery and you can use the NP60 and SLB1037 as a replacement. I will verify once I can lay my hands on the parts.

AA Battery Case
Some people have had good luck using an AA battery case for the Yaesu VX-3R, part #FBA-37, with their UV-3R. I've got the Yaesu part and have ordered another knock-off one from eBay. RPComms43 posted pictures indicating that a small modification had to be made to the plastic case before it would fit. Again, once I have the parts in place I will update and show how it worked for me.

I will once more suggest joining the UV-3R Yahoo Group. These guys are smarter than me and have been really great at getting answers to those that ask.

Baofeng UV-3R: Firmware Hacking

I'm way behind on this topic, but I am posting this in case you haven't see it at all. Lior is working on a custom firmware for the UV-3R. (He started with the UV-5R, but moved to the UV-3R when the project looked to be easier.)

If you have suggestions for features, he's started a thread on the UV-3R Yahoo Group.

Baofeng UV-3R: Mark II

The internet is all a twitter with news that there is a new version of the UV-3R - the Mark II.



No one knows yet, but speculation abounds that the loud volume and other issues may have been fixed. Also, perhaps this version will work with a speaker-mic. The only certainties are the new dual frequency display and a dual-band antenna.

One of the VeroTelecom sites has been updated to mention a dual display version. FleetwoodDP has them on their site with the new info as well.

Andy posted on the UV-3R Yahoo Group with some additional info:

"Got an email today from 409 shop. I asked about whether the Mark 2 is able to do dual receive FROM the memories (Mk1 cannot, you have to dual watch in VFO mode only). Apparently you can (hooray). The cycle between the frequencies is apparently every 5 seconds. Also you can do VV/UU/UV modes too. The Mark 1 cannot, it can only switch between a VHF and a UHF frequency."

I'm disappointed to see a new Yahoo Group for the UV-3R Mark II. I'd be surprised if they are so different that it is worth a new group.

I'll post more as people start getting their hands on the Mark II.

Baofeng UV-3R: US Re-seller - Import Communications

Some facts plus some guessing on my part...

I think Ed of wouxun.us might be setting up to sell the UV-3R.

Follow along...

On the Wouxun Yahoo Group, Ed responds to some comments about the UV-3R:

"The factory has applied for Part 90 certification, which may take about a month.
Hopefully they will be distributed in the US by a company, Import
Communications.

Regards,
Ed Griffin
www.Wouxun.US"

So he knows the factory has applied for and hopes to have their Part 90 Certification in a month. I had not heard that anywhere else and I've been trying to keep up with any developments on this front. I tried looking for Import Communications via Google, but didn't really find anything. On a whim, I tried http://importcommunications.com/ and got the following error:

I believe that http://www.kmaantennas.com/ is Ed's original/other business. A quick whois check confirms that Ed is the owner of the Import Communications domain and that it was registered about a year ago.

Lastly, I did look and see that Ed is a member of the UV-3R Yahoo Group. This doesn't mean a lot by itself, because it would make sense for him to an eye on the competition, but I'm adding it to the pile of circumstantial evidence.


Worlds collide - Wouxun and Baofeng! It makes sense that he might setup this more generic company to sell multiple brands. I'm actually a little jealous. I thought about trying to set myself up as a re-seller, but didn't have the courage or time to really pursue it. I hope I am correct, because I think Ed will be a good guy to sell these things.

Baofeng UV-3R: Review by Dave, N9EWO

Paul has pointed me to Dave's (N9EWO) review of the, as he call its, the VGC / Baofeng / Magiksun / Comtex / Zastone UV-3R "Micro" Dual Band Handheld Transceiver. You have to scroll half-way down to find the start of the UV-3R info, but it is worth a little mouse work. He has lots of good information.

First, he's found two other brands the radio is sold under - Comtex and Zastone.

Second, he's encountered a few problems with the radio and has some fixes like this one for :

"When we do PC uploads to the UV-3R transceiver using the "409shop's" Universal USB cable,the 5 Khz channel step appear like this [B. 4BK] on the LCD afterwards on some memory channels and/or each VFO . Software version used : 1.01.01.
We cured this bug by going to Menu # 9 after and just rotating through the loop of "steps" once to wash out the weird step entries (done after every upload ).
Needs to be done for both VHF/UHF VFO AND also for EVERY memory channel used to clear these weird entries out and for the display to show properly ."

He also mentions the slow scan times and loud receive audio, but comes to the same conclusion that we all do:

"Cheap, Fun and Useful."

Radio's currently listed on BaofengTech (Plus some additions):


Generation Zero:
~~~~~~~~~~~~~
UV-3R, 3R+ (UV-100, UV-100 MKII, UV-200, UV-200 MKII, UV-3R MKII, Vero Electronics UV-X4.
The improved Vero Electronics UV-X5 = TYT TH-UV3R probably belongs here too*).


First Generation:
~~~~~~~~~~~~~
UV-5R, UV5R+, UV-5RA/X, UV-5RC/X, UV-5RE (and most re-branded clones such as the Ronson UV-8R, the Waccom WUV-5R . 409Shop models - UV5R[A-Q] ** belong here too. also if they have + or UU after the model number, it just means that the frequency range was extended by software on the UHF band from 400-470/480 to 400-520, not an improved firmware ).

Slightly better receiver and newer firmware:
UV-B5, UV-B6, UV-82 (=UV82L), UV-82X (=144/220 Mhz model), UV-82C, (And probably the F11, BFUV66 and BFUV89 belong here too).


Second Generation:
~~~~~~~~~~~~~~~
GT-3, A-52, B-580T, BF-F8+ (Also BF-530I, BFE500S and maybe BF-F9+  ***).

Notes:

* Vero Electronics UV-X5 = TYT TH-UV3R probably has some small changes in the filter section, similar to what RadioMart\Martyn was trying to do with the TYT TH-UVF9 that probably became the TYT TH-UVF9D.

Ref5: http://www.tyt888.com/en/Products/Detail.asp?ID=2068
** 409Shop models names UV5R[A-Q] might have added letters to indicate the color R/BLUE/CC 
*** Note the lack of [BAND] button on second gen radios that have the UV-5R form - the BF-F8+, the 409Shop's Baofeng BF-F9+ and possibly other clones that we will see in the future.

I hope this will put an end to the Baofeng/Pofung model variation confusion.
