Baofeng UV-5R: Tri-band

I have not been paying much attention to the tri-band posts on the UV-5R (instead looking at the TYT TH-UV3R running 220 or the 2M/220 specific model of the UV-5R). The following post did catch my eye with its certainty that it works on all newer firmwares.

Instructions on how to make all recent UV_R5 radios run 200 band wiith 136+400mh
"I have just come back to the forum after a month or so and I am suprised to see the big response there is to my original post . Look there is no debate if it works or not------------it does.All UV-R5 radios- Firmware BFB291 and Newer-will TX-RX 220 with 2 meter and 440. I have done this to 3 radios The new 220 radio is a ADVERTISEING GIMMICKbaofeng did not advertise that all the new radios would be 220 and did not release instructions-I discovered this through trial and error 
This is exactly how to do it.
This method is for Firmware BFB291 and Newerto find your firmware --turn on radio while holding the 3 button- look at screen 
download this program BF5R_VIP_v120725_BFB291_ENG(VB6).zip
from here-----http://www.miklor.com/uv5r/UV5R-Software.html
these instrucktions assume your radios cable driver is installed correctly if they are not this program can be used to get them going.
1---unpack zip ---install and launch program.
2---press comunication menu and click com 3
3- plug in radio and press the-- Other-- menu
4--click the check box that says work band-it will switch from 136-174/ 400-520 to 136-174/ 200-260 --type in 200 to 260 in the UHF boxs.
5--- press write to radio on the 'Other' menu--your radio led will flash during download.
6-- press VFO button on radio to VFO mode and you will see on channel A__ the 400 band number has changed to 200.000you can now program 200 band simplex--- and repeters on the radio- -2 meter and 400 band programs will continue to work.
7--now that the radio has been switched to 200 bandPress the 'program' button on software --press ""read from radio"" this will switch the software so that the spread sheet will take 200 band.
8-- press the edit menu -press channel informmation you will see the 2 meter-and 400 repeters that are on the radio on the spread sheet and now it will accept 200 band programing but not 400.
9-- press program menu --press write to radio and now 2 meter -400 and 200 band programs will be working all at the same time!!!!!!
9-- remember!! first you must switch the radio 200 0r 400 with the '' Other"" menu, Then upload back to the software to program with the spread sheet.-- then write back to the radio to make allthem work.To use 200 with 400 and 2 meter the frequencys you want to use must be in a program.
10-- Follow theses instrucktions and you will have a 3 band radio instead of 2 Do this before you say it doesnt work!!!!

73 AND CLEAR SUPERFROG"
Maybe all radios are tri-band. I should pull out my UV-3R and see if I can work some DX on 20M. Crazy, crazy, crazy.

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.

** 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.

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:

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-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 library.zip 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 library.zip
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 Tech UV-2501+220: Tri-band Antenna and Mount

I really like it when it appears that companies think things through. So if you are going to offer a tri-band mobile like the UV-2501+220, you should probably sell an antenna to go with it. And that's just what Baofeng Tech is doing. They are offering the Nagoya TB-320A tri-band antenna ($57.95) and Nagoya RB-35 5/8 NMO Mount Magnet ($22.99) - details of each below.

(EDIT: So apparently all the antenna and mount links go to the same place. You'll have to select antenna or mount on the Amazon page to see the details for each.)

Nagoya TB-320A - Fold-Over 39-Inch PL-259 Mount Triband 2m/1.25m/60cm (144/220/430Mhz) Antenna:
The Nagoya TB-320A is a 39 inch tri-band UHF (PL-259) mount antenna with up to 5.5 dB of gain. It is designed to be used with your mobile or base radio. An included SO-239 to NMO Adapter allows for flexible installation to both UHF and NMO set-ups.

Fold over design allows the Antenna to Fold-Over which allows you to easily put the antenna down in parking garages or in other places where height matters.

The Nagoya TB-320A triband is a 2 meter, 220 MHz (1.25 meter) and 440 MHz mobile antenna. It is a 1/4 wave on 2 meters providing 2.15 dB gain and a 1/2 wave on 220 providing 3.8 dB gain and a 2 5/8 wave on 440 MHz providing 5.5 dB gain. This antenna can handle up to 200/100/200 watts.

Included in the package is a SO-239 to NMO adapter.

Package:

1x Nagoya NB320A Antenna (PL-259 Base)
1x SO-239 to NMO Adapter




Nagoya Antenna magnet NMO mounts are premium quality magnetic antenna mounts with very good holding power. They are a heavy 2 lb magnet mount (durable hold) with a 3 5/8" diameter base, and are recommended for antennas up to 45 in. tall.

Package:
RB-35 NMO Magnet (18 Feet RG-58)
Rain Cap


So add the UV-2501+220 radio, the antenna, the mount - and you are ready to rock and roll mobile!

Baofeng UV-3R: Cheap UV-3R Repeater


Bart (eo512) has created a UHF repeater using two UV-3R Mark II and a small UHF duplexer. He thinks he'll be in the hole for less than $200 (excluding antenna and feedline) for the project.


I'll have to check back later as he indicates he'll add more notes about the setup.

Baojie BJ-UV55/HYS TC-UV55

Given the luke-warm reception of the Wouxun KG-UV920R, everyone is looking at some alternatives. Following is a essentially a guest post by Nate as he reviews the HYS TC-UV55 (Baojie BJ-UV55) by watching a video review by Andre Silva of Brazil. These mobile radios were first mentioned in his earlier Mega List guest post. I've done some editing, so assume any mistakes are mine. (Already updated as I've made plenty of mistakes! Hopefully, they are fixed now.)

Many thanks to Nate for the in-depth review!

Here is basically a "second hand" review as the video is not in English and Nate could not understand what he was saying. Basically, he watched the display and compared the specs listed in the catalog page.

This video consists of two parts. It is probably not a complete overview of all the features and menus of the HYS TC-UV55 - some key features weren't even showed. (He was using the pause buttons to check out all the settings, etc). The unit sells for about 2/3 of what they want for the KG-UV920 on AliExpress. Actually, the video is about the HYS TC-UV55 (which is essentially the same radio as the Baojie BJ-UV55 based on the specs and this video).

Part 1 Highlights

- Unique way to enter frequencies, the MHz button actually allow you to change digit by digit, most radios will just allow 1 MHz steps, and then you have to scroll up or down up to 500KHz .
- 36 Menu items (00-35).
- Offset steps - 10 KHz. Same digit by digit entry Offset Frequency (can be set between 0 and 69.9875 MHz in Frequency Mode).
- To switch between VFO and Memory Channel mode, he turned off the radio, held the MENU button while turning the radio on again. This seems odd, but I don't understand what he says. There could be a more conventional way to switch between VFO and Memory Channel. Here is a video from Thailand showing the Baojie BJ-UV88 HT radio and the guy demoing the radio did the same on the HT.
- The display can do VV VU - U+V,U+U,V+V,V+U dual band working mode can be selected arbitrarily Dual Frequency standby in any band.
- The button to the left of the MENU button, is the SCAN button.
- BDR function? TX-AB function?



Part 2 Highlights

- The display backlight can be turned off.
- Separate Tone Squelch or Digital Code Squelch can be set for TX and RX.
- The video gets cut at the end, but no Part 3...




Misc Notes
- A lot of similarities to the Baofeng UV-5R (The menu system is actually the same as the Baojie BJ-UV88 handy talkie).
-The Menu button is used to enter the item/save the change.
-The display shows a used memory channel the same way the Baofeng UV-5R does: CH-001 - used channel 1, 002 - empty memory channel 2.
-Like with the Baofeng UV-5R, programing a channel for the second time, the second frequency will become the TX frequency, the first will be the RX frequency, the display will show +-

HiGrade HG-109

Nate has been looking around for the latest radios and come up with some good stuff. So, thanks to Nate! I'll start with this one - the HiGrade HG-109 which is described as:
"Handheld Walkie Talkie big screen MP3 MP4 two way radio with Camera,Video Recorder,Box Speaker 2840,FM radio,Clock,Calculator function"
Other specs are below, but check out the screen.




Nate points out some of the interesting features like MP3/MP4 player, built in digital camera + video recording capability. He also notes that one of the pictures shows a calendar with a January 2012 - so either that is a test date or this thing has been in development for awhile. I'm also confused by the listed frequency range (400 - 470 MHz) that doesn't match the "Dual Receive Yes (VV/UV/UU)" line.
