Baofeng UV-5R: UV-5RAX 2M + 220

"It works, with a few small issues. The radio was marked with a decal in the battery compartment as a 2m/440 radio. A call to Radio-Mart told me to check the antenna markings and power up, sure enough the little rubber attenuator is marked 2m/220 and using a charged battery from my 440 unit the display shows 220. When using the latest VIP programming it will allow me to place the 222 freqs in but chirp will not allow it (the chirp is a one month old nightly) 
Power on with holding the #3 key says BFB-296. Talked last night on the net with no issues. All the accessories such as the extended battery and car adaptor are also fine. Only distinguishing cosmetic is the front labelling with some reflective type as a dual band If you needed an extra battery for your 2/70 uv-5ra then this is only 35 bucks more for another radio with a 220 band. It was shipped rather quickly also. So far so good." 
"Need to get a sma to pl adaptor to check actual power."

Puxing PX-888K: Follow-Up 2

Good things come to those who wait... Hans has completed his full review of the Puxing PX-888K. He's taken the original post and expanded on it. He still gives it a thumbs up:
"I like the Puxing PX-888K, but the radio is not without flaws. Phase noise is generally low, but the signal is not entirely clean. TX audio is muffled. The jacks for connecting programming cables and headsets can give you trouble later in time. Harmonic suppression is fine though, and the receiver is quite good. RX audio is brilliant – the most beautiful sounding audio to date. 
In spite of the price I can still recommend this radio, but using a good speaker/microphone is recommended."
Having never used one or even seen it in person, my contribution to the discuss of the PX-888K is: I like the green color. It has cool retro feel to it.

I did just check CHIRP again and did not seen other notes about adding support for the PX-888K.

Puxing PX-888K: Follow-Up

Hans previewed the Puxing PX-888K and I linked to his post. I even made fun of the fact that you could get a free shirt or jacket if you bought them in bulk. Some how I missed his follow-up of the actual review - Review Puxing PX-888K Part I - First Impressions. (No Part II yet, but he did mention the PX-888K in August when talking about the MYT-Q2.) Here are some key parts from his review:

Good build quality, nice features (like CTSS, DCS, DTMF, 1750 Hz burst tone, ANI), easy programming and "pleasant" receive audio, but "TX audio is still muffled, and the lack of highs makes your transmission hard to listen to."

The lone review by KD8DVR on gives the PX-888K a thumbs up. He seems happier with the transmit audio - just comments it is a little "bassy." He's also posted a more detailed review on He specifically mentions that he has no trouble with the muffled audio that is common to Puxing. He does wish the battery life was better.

As with most Chinese radios, everyone is unhappy with the scanning speed.

The PX-888K has Part 90 acceptance - FCC ID: AUJPXDZ888K001. If you go to the FCC site, and search for AUJ in the Grantee Code  field, you can see the documents submitted for approval including pictures, manuals, etc.

Surprise - there is a Yahoo Group for the PX-888K! Only 77 members and 131 posts as of right now.

Current price is $80.00 with speaker mic at 409Shop. Or $89.95 at Kight Radio if you want a US dealer.

One update, there is still no CHIRP support, but it is on the list.

Here is the usual unboxing video courtesy of the 409Shop.

KG-UV920R: Programming from your PC

So the programming software for the KG-UV920R was uploaded to the Wouxun Yahoo Group. And it turns out that Wouxun has called the software: KG_UV920R Commander V0.1.0. Beta - Programming Software by Wouxun. Ed notes that Wouxun is aware they have appropriated the name "commander" that has been used by Jim for his popular KG-UV Commander software for quite some time.

I guess we should just be happy they didn't call it the Commander CHIRP programming software.

I also see you can get the USB programming cable on eBay now.

Updated after posting: VA3ISP has a fix for an import error when trying to use the software with an Excel file.

Baofeng UV-5R: CHIRP Bug

I have been kinda busy the last few days, so I missed a little tempest in a teapot when a new release of CHIRP started bricking UV-5R radios. There was a flurry of messages regarding squelches that would not close, no transmit/receive, no FM, etc. The problem was reported as bug #210 to Dan. The good news is that he was extremely responsive, found the problem, and got a new release out, and posted instructions for fixing the problem are here.

Quansheng TG-UV2: CHIRP Support

Looks like CHIRP support for the TG-UV2 may not happen in the immediate future:
"Dan replied to my inquiry with the following: " It depends on the radio, of course, but if it is going to happen, it would take less than a week of development time. "

He didn't venture when that week might occur. And that tiny word "if" looms large.

I didn't see a way to vote/show support for a particular radio on Dan's site. He's doing this for free, so whatever he decides to do next is clearly up to him. As a quick data point, the relative Yahoo Group memberships are:

TG-UV2 - 431
UV-5R - 1,126
UV-3R - 3,118

Baofeng UV-5R: Extreme Receive Modification

[ Don't have a UV-5R yet? Get one here. ]

Alvin and b1gslacker have been editing the .dat file to expand the receive frequencies of the UV-5R. As usual the results are a big of a mixed bag given the limitation of the hardware and software involved. Steve, WB8GRS, details the limiting factors:
"There are two components (the DSP and MCU chips) in the UV-5R that determine the band limits.
 1. The RDA1846 DSP chip is the chip that generates all the transmit and receive functions and it specifies the band limit as follows.
134 MHz to 174 MHz200 MHz to 260 MHz400 MHz to 500 MHz
This information is provided in the RDA1846 documentation in the file area. Many have reported the UV-5R will operate outside of these band limit on the 134 to 174 and 400 to 500 MHz bands (no one has reported any success using the UV-5R on the 222 MHz band), so my guess is the above band limits are not "hard coded" in the DSP chip, but are just guaranteed band limits and in fact some chips may operate outside these band limits to some degree.
2. The MCU which I believe is a custom version of the EM78P568-44 microprocessor tells the DRA1846 DSP chip what frequency to tune. If the MCU does not send the correct commands to the DSP chip the right frequency will not be received or transmitted. If for example you load in a 222 MHz frequency, the DSP chip is capable of receiving and transmitting on 222 MHz, but only if the MCU provides the correct commands to the DSP chip. If the MCU does not provide the correct commands, the display may should the correct frequency, but the DSP chip is doing nothing. Even if the MCU send the correct commands to the DSP chip, the RF pre-amplifiers and RF amplifiers external to the DSP chip are not designed to operate on the 222 MHz band so even if the DSP chip was commands correctly by the MCU, the power output and receiver sensitivity would likely be very bad."
b1gslacker gives the details of how to make the change here. The usual warnings apply - do this at your own risk.
"For those of you who would like to attempt to destroy your brand new shiny UV-5R, here are the instructions for "slightly modifying" CHIRP to accept frequencies WAY outside of the manufacturers recommended operating boundaries. These instructions are for windows XP only (but will probably work for others also)
1) Download the UV5R.pyc file in the files section.
2) Using your favourite zip utility (I recommend winrar) open the file located in your C:\Program Files\CHRIP\ directory (location may slightly differ based on your flavour of windows, but you get the idea).3) Delete the UV5R.pyo file from the zip4) Add the UV5R.pyc file5) Save the modified
I know that your thinking, but if you don't understand the instructions, you should definitely not be trying this, so don't even ask.
Now that you have installed the "ever so slightly enhanced" version of the UV5R CHIRP module you should be able to program frequencies between 10MHz-999MHz in the CHIRP application.
NOTE: Even if the radio accepts the frequency and displays it on the LCD display, this does not mean that the radio will actually work on that frequency (in fact we do know that there are definitely limits)"

Baofeng UV-5R: Alphatags 7 Characters via CHIRP

Timing is everything... Last night, I finally got around to updating the 7 Character Hack post with a Google Cache link to the missing instructions. So, what do I read this morning?

CHIRP will now do the heavy lifting for you and update the radio with 7 character alphatags. Daily builds are here.

Baofeng UV-5R: CHIRP Support

Ed (Import Communications) sent a UV-5R to Dan, so that he could add it to the list of radios supported by CHIRP*. That was three days ago and Dan has already added support for the UV-5R in his daily builds!

*"CHIRP is a FREE cross-platform, cross-radio programming tool. It works on Windows and Linux (and MacOSX with a little work). It supports a growing list of radios across several manufacturers and allows transferring of memory contents between them."

Baofeng UV-3R: Mark II Software

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

UPDATE 11-12-12A 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!

Baofeng UV-3R: Guest Post/Review at

Matt, over at, asked me to do a guest post at his site. The following UV-3R review first appeared there on September 2, 2011. 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 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.

Functions and Features
- 50 CTCSS, 104 CDCSS
- Time-out Timer (Off/30/60/90/120/150/180 secs)
- Shift Frequency

- Squelch Set (1-9 Levels)
- Electronic Volume Adjusting (8 Levels)
- Keypad Lock - Backlight (On/Off/Key)
- Tail Tone Elimination
- Battery Save
- Restore to Factory Default
- PC Programming
- FM Radio Channel Storage

Battery Life | 10 hours
Dimensions | 1.9" x 3.2" X .9" (Approximate)
Weight | 140g

Technical Specification - Transmitter
RF Power Output | 2W

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:

Menu #
Name Description Options
1 RXCODE Receive Tone Off, CTCSS, DCS
2 TXCODE Transmit Tone Off, CTCSS, DCS
3 SQL Squelch 0-9
4 LIGHT LCD Illumination Off, On, Key

7 POWER RF Output Power High, Low
8 DW Dual Watch/UHF & VHF Off, On
9 STEP Freq Size Step 12.5/25KHz
10 OFFSET Repeater Offset 0-37.995, 0-69.995M
11 SHIFT Repeater Shift 0,+,-
12 STE Squelch Tone Elimination Off, On
13 W/N Wide/Narrow Receive Wide/Narrow
14 SAVE Battery Save Off, On
15 TOT Timeout Timer Off, 30, 60, etc.
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: CHIRP Now Available for Testing

You've got to love software with frequent builds...
Support is added in today's build:

This is a first stab and only represents a couple hours of work, but it
seems to work for me. Feedback is appreciated, although I'd prefer it go
to the chirp_users list if possible. Future fixes and enhancement
announcements go to that list.

Software One for the Valentine One Radar Detector

I was looking at the KG-UV Commander software again for the previous post about CHIRP and I noticed KC8UNJ's link to his Software One application for the Valentine One Radar Detector. I don't even have a radar detector, but I still think that's pretty slick. If I were a programmer, I think I would have to learn how to work with serial communications - that stuff is everywhere. I would be all powerful if I could talk to machines through the serial port and do database selects, inserts, deletes, and updates on the back-end!

Universal Radio Programming Software - CHIRP

Instead of having a program to update the UV-3R and a program (or two!) to update the KG-UVD1P, how about a "one size fits most" application for programming radios. CHIRP will update, as of this writing, three Alinco, seventeen Icom, one Jetstream, seven Kenwood, nine Yaesu, and three Wouxun models. It will not do everything the radio specific software will do, but will update the basic memories for your favorite frequencies. You will still need the appropriate cable for your radio.

Baofeng UV-3R: Software

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

UPDATE 11-12-12A 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.
