Several Dual Band DMR handhelds have been introduced into the market in the past few months. Having owned most of them, I would have to place this one toward the very top of the list. The DMR-6X2 is both VHF and UHF, Tier II DMR digital as well as FM analog with most features geared strictly toward ham radio use.
Important Note: The BTech DMR-6X2 is Not made by Baofeng. (see note below). That being said, let’s see what’s…

Basic Description (additional features)
The heart of the 6X2 is the proven Anytone D868. Under contract with Anytone, BTech had several addition features exclusively added to the 6X2.
Some of the additional features exclusive to the 6X2 include:
– Multiple Scan Groups
– Priority Scan
– Change TG via Keypad (Adhoc) with Unlimited Hold Timer
– Display Color Options
– Digital Simplex Repeater
– Analog Squelch Level Adjustment
– Start Up Code Plug Compatibility
– Display Hold
– Multiple Scan Groups in Same Channel
The 6X2 allows multiple scan lists to be entered per channel. You are no longer limited to one scan group entry per channel. The scan groups can include and mix of DMR or analog channels.
– Priority Scan
When developing a scan list, up to 2 channels can be assigned as priority. This allows the priority channels to be interwoven in the scan list. As an example:
– Channel 1
– Priority Channel 1
– Channel 2
– Priority Channel 1
– Channel 3
– Priority Channel 1
– Change Group via Keypad (“Unlimited” hold timer)
This is specially nice when using a hot spot. By setting a key function to “Dial” or “Long Press 0”, and the Group Call Hold time to “Unlimited”, you can enter a Talk Group using the number pad and it will remain permanently or until the channel is changed. No longer is the hold time set in seconds or minutes.
– Display Color Options
There are two display color options available. They are White on Black background, and Black on a Powder Blue background. (shown below). They are selectable by either software or keypad menu.
– Analog Squelch Level Adjust
The analog squelch level can now be adjusted using one of the programmable keys.
– Start up Code Plug
To assist with start up, the software was written to initially accept an Anytone D868 code plug. I’ve had a 868 since they first came out, and this was a huge time saver. Everything transferred and I was ready to play radio in minutes.
Note: Due to the extra features in the code plug, a 6X2 CP cannot be transferred back to a D868.
– Digital Simplex Repeater
Not to be confused with a standard repeater, this feature allows the DMR-6X2 to function as a Store and Forward Simplex Repeater. The 6X2 records a transmission and stores it in memory. Immediately after the incoming signal is dropped, the transmitter keys and re-transmits the recorded audio. The re-transmission can be either on the same or different frequency (not necessarily on the same band).
This feature allows the 6X2 to be used as a relay point during events such as marathons, races, etc. where a central relay method is needed and there is no local repeater.
– Display Hold
When a signal is received, the data image (name, call, location, etc) remains on the screen until the next signal is received rather than drop back to a standby screen. There is a Call End indicator at the bottom, but the data remains.
The Technical Side of the 6X2
The frequency range of the DMR-6X2 is both VHF 136-174 and UHF 400-480 MHz. Along with DMR, the radio also supports analog FM (Wideband and Narrowband)
The power levels hold pretty close to the specifications. There are four power levels with a high of 5.0W and a Turbo mode of 6.5W. I personally run mine in 5W mode. Turbo isn’t going to Make or Break the signal, but it helps the battery.
What I do like is the low power mode is less than 1W. I run a hotspot here and if the power was only 0.3W I would be happy.
My audio reports have been excellent both through a DMR hotspot and the local repeaters. There is a five level microphone gain parameter that allows you to select the microphone gain level that best suited for your voice. I use level 3 (mid-level) for a full smooth audio response. I tried level 5 and found the audio was way too hot.
Power levels are listed below and were taken using a calibrated Bird Termaline wattmeter.
The DMR-6X2 case has a good solid feel and weight, and fits the hand well. It weighs in at 9.9oz (282g) with the standard battery attached and 10.8oz (306g) with the high capacity battery. Battery removal requires a simple push of the release slide located at the top of the battery. No battery sliding or pushing is required.
I found the keypad buttons a bit larger than most with a lighted keypad layout of three across and four down. This puts the zero (0) at the bottom of the keypad where I believe it belongs. The PTT button requires only a light pressure that doesn’t tire the finger to press.
The included dual band antenna is 6.25″ which is a fairly common size for a handheld. I found that there was a slight improvement of about 2db by using an NA-771. The 771 is 10″ longer, so a difference would be expected, but I’ll probably stay with the stock antenna.
Receiver and Audio
The receiver sensitivity is very good on both digital and analog. I found the receive audio is amazing with wide and smooth frequency range.
The volume control range is adjustable with the software. Level 1 sets the full range of the volume control to a soft level, even at full volume. Level 8 sets the volume range to very loud at the top end. My preference is level 3 to 5 which is plenty loud, even for mobile operation.
The radio has a two multi-color display options. The high contrast White on Black, and the softer is a Powder Blue with multi-color icons. The color is selectable via software or as a keypad menu option. The screen size is 1.1″ x 1.4″ with excellent resolution .
There are multiple sites where the current DMR User Database can be downloaded. There are various formats available allowing you to view name, call, location, user ID, license class, etc.
Along with entering data in the conventional manner, the software allows you to import and export data to ‘csv’ files. Loading in a contact (TG) list, channel list, database, etc. is relatively simple.
I found being able to export to a ‘csv’ file has several advantages. I like having my channel list in sequence. With most software, you can only add new channels to the bottom of the list. Now I can sequence the list so it’s easy to view then load it back into the code plug.
Adding a new repeater can be done in minutes. I just cut and paste a copy of an existing repeater, change the frequencies, and load it back.
Note: The BTECH 6X2 can import a code plug (.rdt) from an Anytone D868UV directly. This is a great way to get your 6X2 on the air. Once loaded, however, due to the expanded parameters, the D868 is not capable of reading a 6X2 code plug.
CSV transfer Caution
Adding large amounts of data, updating and re-sequencing via CSV files is a major plus, but should always be done with Caution. For instance, Talk Group data must always be loaded before or at the same time as the Channel data. If not, improper data attachment may not occur.
Always backup your current code plug before modification.
As additional features and future enhancements are developed, the radio can be updated to latest model. A firmware upgrades can be done with a Windows computer in about 5 minutes.
Note: The DMR-6X2 firmware is specific to this radio. It cannot be uploaded to a different model in hopes of adding new features.
The DMR-6X2 comes with the necessary programming cable. The UART chip inside the radio, so the cable itself is straight through. There is no circuitry inside the cable itself. The driver will load automatically when the cable is attached.
For reference, although the cable appears to be the same as some that have the chip in the cable, those cables are not compatible.
The charger base requires a standard 12vdc wall wart (included). The LED on the front of the charger base is Red when charging, and Green when either fully charged or no radio in the cradle. The battery easily charges to full capacity with an overnight charge.
Battery and Charger
There are two batteries included with the 6X2, a 2100mAh and a high capacity 3100mAh. With battery save on, I can get 2 to 3 days out of the 3100mAh battery before needing a charge.
There are also USB charging cables available with output of 12V. These can also be used in place of the included Wall Wart.
If you think the BTECH DMR-6X2 very closely resembles a D868UV, you are correct, but as shown above, it is definitely not simply a rebadged Anytone. There are features and enhancements that set these two radios apart. I think BTECH was wise to wait for the bugs to be ironed out before introducing the 6X2 to the market.
If you’re waiting for this radio to drop in price, don’t hold your breath. Its features and performance make it well worth the price.
The obvious pros are the following:
– True Tier II DMR
– Same Band and Cross Band digital simplex repeater
– Dual Band VHF/UHF operation
– Multiple Scan Groups per Channel
– Priority Scan
– On the Fly Talk Group Entry
– Built-in Voice Recorder
– 2TONE and 5TONE decoding
– 150K user database capacity
– FCC Part 90 certified for commercial use
– N0GSG Contact Manager Compatible
There are plenty of options geared more for hams than commercial use. It performs well and makes a nice addition to the ham shack.
Available from: and Amazon
BTech (BaofengTech) is not a division of Baofeng. They are an ODM that partners with OEM manufacturers to spec and build to their own requirements, whether from scratch (UV-5X3) or from an existing product. This 6X2 is an Anytone at heart with additional unique features found only in that model.
The AMP-25 series VHF / UHF Amplifiers
The recently announced BTech Digital and Analog amplifier series puts a whole new spin on mobile operation. It performs more like a mobile than it does a power amp. The D series are true TDMA Tier2 DMR amplifiers.
Note: This review was done using an Anytone D868UV on both DMR and analog.
In the Box
Included with the 40W Mobile Amp are:
– Mounting Bracket
– 3′ Interface Control Cable (Kenwood K1 connectors)
– 3′ RF connect cable (SMA-M to SMA-F)
– Microphone and Hanger
– All necessary mounting hardware
– User Guide
– UHF or VHF Power Amplifier
– 2-6W > 20-40W Output
Modes of operation include:
|V25 U25||V25D U25D|
P25 (Phase 1)
| > DMR Tier II (TDMA)
> P25 (Phase 2)
P25 (Phase 1)
A Different type of Mobile Amplifier
I found these to be much more than a typical power amplifier. Although they can function as a simple ‘In and Out’ power amp, this is about as close to a full mobile as you can get. Although the driving force was my DMR handheld sitting in my cup holder, the transmit audio was that of the included hand microphone and the receiver audio out was coming through the built in speaker driven by a four watt audio amplifier.
I tested the power on two different models. The VHF V25 (non TDMA) and the U25D for UHF DMR. The power was tested using the analog side of both into a calibrated Bird Termaline wattmeter. The maximum current drain from my 13.6V 30A power supply was just under 6A. This is low enough for the amp to be powered by the 10A accessory jack in your vehicle.
The basic frame measures 4.6″W x 1.3″H x 5.5″D (excluding the SO-239) and weighs in at 26oz. I was curious to see the internal layout of the amp and to no surprise, there was a 5/8″ finned heat sink spanning the entire length and width of the case along with air vent along the back of the enclosure.
These are single band amplifiers.
V25(D) = VHF 136-174MHz
U25(D) = UHF 400-480MHz.
Note: The V25D and U25D were designed to include DMR Tier II (TDMA) and P25 Phase 2 along with all other modes. Their operation varies slightly.
V25 / U25
To operate VHF through the UHF (U25) amplifier, or UHF through the VHF (V25) amplifier, simply power off the amplifier. This will allow you to run straight through directly to the antenna without power amplification on that band.
V25D / U25D
These amplifiers will only operate within their specified VHF or UHF range. This is due to the circuit switching design of DMR Tier II and P25 Phase 2.
The simplest configuration is using the included RF cable to attach the radio to the amp. You could add a Spkr/Micr to the handheld, but you would still be bypassing some of the best features.
I use the two included cables. The 3′ RF cable to attach the radio to the amp, and the control cable. This allows me to use the full size hand microphone as well as connecting the four watt audio amp powering the speaker. The power included power cable is compatible with handhelds using the standard two pin Kenwood style connector, such as an MD380, D868, GD77, UV5R, F8HP, UV82, etc.
I use an Anytone D868 on DMR as well as analog with the hookup diagrammed below. Depending on your radios antenna jack, you may need to pickup an SMA-M to SMA-M adapter.
All channel selection and volume adjustments are done using the handheld. No duplicate programming or code plugs are necessary. Whatever is in my handheld is what I operate in the mobile
Operating my handheld in the low power position, I still get 22W out on UHF and my handheld’s battery life remains excellent, but high power gives me a solid 39W.
I was glad to see someone finally develop what is a full featured mobile amplifier capable of DMR as well as all other modes including C4FM and D-Star that is small enough to mount in the car, boat, and on top of your computer. This amplifier is Part 90 certified and definitely worth considering.

I’ve been wanting to get involved with APRS for a while now, and this made it extremely easy.
APRS-K2 interface cable
The APRS-K2 cable allows you to interface your handheld transceiver with your existing mobile device, including. iPhone, iPad, and Android.
One end of the cable uses the Kenwood style K2 connector, while the opposite end is terminated with a TRRS connector. Also included with the APRS-K2 is a Reverse Adapter to insure compatibility with all devices. This adapter allows cable to connect to earlier 3.5MM TRRS standards, such as Nokia.
The APRS-K2 cable uses a virtual TNC found in several apps, such as APRSDroid, APRS.fi, and Pocket Packet. Plug in the cable, turn on the VOX, and you’re pretty much set to go.
BTECH APRS-K2 TRRS / APRS Cable A simple way to start using APRS by using devices you already own. The BTECH APRS-K2 Cable will quickly connect your radio to APRS by using virtual TNC (app driven) on your tablet or device. The APRS-K2 cable is built with a custom circuit board that will automatically adjust the audio for clear packet transmissions with minimal adjustment; along with protecting your devices from strong over modulated signals.
Along with allowing APRS functionality the APRS-K2 cable can provide a simple interface gateway to allow several features to your radio!

Although the case design is familiar, the radio inside is not. BTech has recently introduced the new UV-5X3 to the US Ham Radio market. This radio is a true triband transceiver with internal filters specifically configured for triband operation.The firmware in this radio has been reworked to include several new features not found in similar appearing radios.
In the Box
Included with the radio are the:
– 1500mAh Li-Ion Battery **
– 85 page User Guide – English
– Charger base & AC adapter
– Hand strap
– Belt clip
– PTT Earpiece / Microphone
– Antenna (1) – VHF / UHF 6 3/4″ (17cm) A-V85
– Antenna (2) – 220 MHz 6 1/4″ (15.5cm)
** This is the identical battery that is commonly mislabeled as 1800mAh on some handhelds.
The UV-5X3 was specifically designed as a Tri-Band transceiver. The internal filtering allows not only the traditional VHF and UHF frequencies, but also includes the 222-225 MHz Ham band for the US.
The UV-5X3 has the traditional case design, which allows me to use my high capacity BL-5L 3800mAh battery with no alteration to the base. Accessories such as my mobile battery eliminator, Spkr/Micr, etc. are fully compatible.
The frequency range is VHF 130-176 / 222-225 / UHF 400-480 MHz, supporting both Wide and Narrowband with 2.5kHz steps.The radio’s filtering scheme allows for full power on all bands. My OTA audio reports have been clean with clear with mellow audio. Power levels are respectable using a Bird VHF/UHF Termaline.
DTMF / IRLP Access
Something new also appearing on this model is a DTMF gain adjustment, allowing me to adjust the DTMF audio to the transmitter to a comfortable level for both repeater control and IRLP access.
If you are in a area that requires tone burst for repeater or network access, the 1000Hz, 1450Hz, 1750Hz, and 2000Hz burst are accessible by pressing the PTT along with one of the four pre-assigned keypad keys.
The receiver sensitivity is excellent, and the audio quality is clear, loud, and undistorted. Along with the 3 TX/RX bands, the receiver also includes the traditional commercial FM radio band. (65MHz-108MHz)
Tone Scanning – The receiver also has the ability to identify the tone of a repeater being transmitted by a received signal.
This feature gives me the ability to add / delete channels from the scanning list using the keypad. No longer a software only function. The more I can do from the keypad, the better I like it.
A Long Press of the [*SCN] button will start the scanning process.Channel Mode – When scanning with the Display Sync set to ON, the upper and lower display will scan together. This is explained below under Display Synchronization.Frequency Mode – When entering Scan, the image below will appear on the screen. Enter the first 3 digits set the range start, the second 3 digits sets the stop.
Example: Entering 146 : 146
Start the scan range at 146.000
Ends the scan range at 146.999
I found two antennas included with the radio. One was the standard upgraded A-V85 antenna, and a slightly shorter one for the 220MHz band.
Antenna (1) – VHF / UHF 6 3/4″ (17cm) A-V85
Antenna (2) – 220 MHz 6 1/4″ (15.5cm)
The separate antenna specifically tuned for 220 MHz is a great addition. The SWR shows 1.3 which is excellent. No compromise. I labeled my 220 antenna, as they are very close in appearance.
The radio has a tri-color display, allowing the color options of the blue, orange and purple. The LCD can be formatted in either of three formats. Choices are Frequency, Channel number, or up to 6 Alpha Characters.Display Synchronization
The UV-5X3 supports display syncing, which gives ability to track both the upper and lower LCD. I keep mine set to display the channel name in display A, and the frequency in display B. When you change the channel, both the upper and lower displays move together..
Manual programming is pretty straight forward once you enter a few channels. A programming guide can be found at Manual Programming with a Menu Definition summary available at Menu Definitions.
The software support for the UV-5X3 can be found in the Latest Daily Build of CHIRP. There are a few new options that will be added to the 5X3 in the near future. One is the ability to Stun, Kill, Revive. This gives you the ability to disable your radio remotely.
The new chipset (RDA1846S and RDA5802N) provides reduced AGC switching noise and a low-IF digital audio processor for improved sound quality.
The programming cable requires a traditional two pin Baofeng / Kenwood style. There are several cable available. The generic cables may require special drivers, due to the use of cloned chips. For Plug and Play, a cable using an FTDI chip is recommended. Conclusion
The UV-5X3 firmware has obviously been reworked to include:
– Tri-Band Support: VHF/1.25M/UHF
– D-ANI (Display incoming DTMF Tones)
– Synchronized Displays
– DTMF audio gain level adjustment
– Add / Remove Channels from Scanning list via keypad (LCD Dot Indication)
– On the Fly scanning by Frequency Range
– 4 Tone Burst options
– Remote Stun, Kill, Revive
Last week I cleared the dust out of my blog and podcast websites and briefly discussed ordering the Baofeng UV5RA HT from Amazon. While this model was released several years ago, Amazon has them available brand new for $26.06. This includes the HT, charging stand and hands-free kit. Here’s the link to the Amazon product page for the Baofeng UV5RA HT.
I guess it’s been several years now since these cheaper (I guess less expensive might be the more PC way of describing these) Chinese made hand-held radios came onto the market here in the US. Fellow hams began showing these off at local club meetings and I began reading reviews of these radios on various amateur radio blog sites from around the world.
For the most part, the opinions expressed all seemed to have a common theme around pricing, ease of use and durability/reliability. Many viewed the low cost of ownership to be favorable over any durability issues. I guess the idea of use it, abuse it and toss it comes to mind. I also seem to remember a strong sentiment of “steer clear” when discussing these units.
I could see all sides of the argument. But I also fully understand some folks just getting into the hobby may be on a limited budget and may not have the resources to afford the latest and greatest from ICOM, Kenwood or Yaesu. As time went by, I really didn’t hear complaints regarding the durability/reliability of the radios. But certainly most everyone I spoke to all said that the programming of the radio was often a challenge and the provided user manual was of little to no help.
As for me and my reasons for not entertaining the idea of these cheaper Chinese made radios all boiled down to the fact that I really didn’t need another HT. I already own more HT’s than I have hands, so I just didn’t see the need.
So what changed?
Last week I was thinking about future topics to discuss on the Practical Amateur Radio Podcast and was researching just how many different HT models were available and the price range. This research led me to all the usual amateur radio dealers as well as a quick check of Amazon. I simply searched for Baofeng and that’s when the UV5RA popped up. With my Amazon Prime membership and a $3.00 credit, I could actually get this HT home for less than $25.00. Deal!
I decided I would gain some first hand experience with at least one of these cheaper Chinese made HT’s and share my knowledge with all of you reading this blog and later on the podcast.
Reverse Bait and Switch???
So my package shipped from Amazon as expected and was delivered on Saturday. I opened the package and inspected the contents. Immediately I noticed something was different.
If you look at the Amazon product page for the Baofeng UV5RA you’ll see the photo below. This is the Baofeng UV5RA. However, the HT shipped to me looked nothing like this.
Instead of receiving the UV5RA (as shown above), I received the UV-82 (shown below).
Initially I was slightly upset. We’ve ordered a lot of items from Amazon. While this was my first amateur radio purchase, it was also the first time I didn’t receive exactly what I believed I ordered. However, after doing a little more research I discovered the following:
First, while the Amazon store page for the Baofeng UV5RA doesn’t match what I actually received. If you carefully read the product description, under the section “What’s in the Box?” you’ll see the Baofeng UV-82 listed.
Second, from what I understand…the UV-82 is an upgraded (newer) Baofeng hand-held. If I read this Baofeng product comparison chart correctly, the UV-82 includes an updated PCB, commercial grade case and other enhancements as compared to the UV-5R models.
Third, the UV-5RA is a 4 watt model with the UV-82 offering 5 watts output.
Did I get what I paid for? Well…not really….but advantage appears to be all mine. I can’t guarantee what will happen if you order the same model I ordered…but from all appearances you’ll also receive the UV-82. Just no guarantees. Alternatively, you can purchase the UV-82 via Amazon (listed as UV-82) for $28.80. It’s a few dollars more than what is listed on the UV5RA product page, but you’ll be guaranteed to receive the UV-82 if that is the model you desire.
How I plan to use the new radio
Before I go into my initial thoughts/review/feedback (what ever you want to call it), I think I should clarify exactly how I plan to use this new Baofeng UV-82 transceiver.
This radio is not replacing anything I currently own. My main go-to HT is the Yaesu VX-8 which I have the GPS module installed. I also own an older Yaesu VX-6 (which I should probably sell) and also the ICOM IC-92 D-STAR HT which I also rarely use.
I actually plan to program a few local repeaters, simplex and NOAA weather frequencies into the Baofeng and leave it at my office. For less than $25.00 I am really just considering this a weather radio that will do a little bit more.
I’ve had the UV-82 now a few days and feel comfortable in sharing some of my initial thoughts on just what I think of this radio. I’ll break my thoughts down under a few different categories.
Over all Design
The overall design of the radio (my opinion) is fine. The radio fits nicely in my hand (not too small, not too big). It sort of reminds me of an older Nokia cell phone from the time when cell phones weren’t smart.
Channel Mode/Frequency Mode
If I’m honest, I really dislike having to power the radio off to switch from channel mode back to frequency mode. While it’s simple enough, just hold down the Menu button while you switch on the radio. All my other HT’s have a button which toggles between the two modes. However, as previously stated…this radio will be programmed with a few local repeaters, simplex and NOAA weather frequencies. For the most part, the radio will be used to listen to weather information from the national weather service.
While I’ve not taken a hammer to the case (nor do I plan to) and I’ve not performed a drop comparison from the top of my building (I don’t plan to do that either). The overall case quality appears to match that of my Yaesu rigs. As I’ve previously stated, the radio fits nicely in my hand. It’s easy to grip and the included belt clip has a nice firm spring. While I don’t plan to use this HT as I use my Yaesu, I also wouldn’t have an issue clipping this onto my belt or pack and heading down the trail.
Stock Rubber Duck Antenna
What’s In Your Rubber Duck? Well this was answered by Bob, KØNR and I would highly recommend reading his excellent review where he reveals the “inner workings” of several popular stock rubber duck antennas (including the Baofeng UV-5R).
But what can really be said about ANY stock rubber duck antenna? Regardless if the radio brand is Yaesu, ICOM or Baofeng, you will greatly improve the radio by installing an aftermarket antenna. I use the Diamond SRH77CA on my Yaesu VX-8 and it works great. But at the moment, I have no plans to replace or upgrade the Baofeng rubber duck.
The LCD screen on the UV-82 is slightly smaller than what I’m used to on the Yaesu VX-8. But to be honest, if I don’t have my reading glasses with me 24×7 these days…and the screen size doesn’t rival the Dallas Cowboys Jumbotron, I’m not able to see anything.
Dual PTT functionality
The UV-82 features dual PTT switch functionality. This is a bit odd (compared to my other HT’s). I suppose in time I will get used to it.
FM Broadcast Band
If this is something you care about, the UV-82 features a button on the side which switches the radio to the FM Broadcast band.
Built in Flashlight
If you are in the need of a hand-held amateur radio transceiver WITH a built-in flashlight, then the UV-82 is the rig for you. A conveniently placed button on the side will turn on/off the flashlight.
This is the radios weakest link and is perhaps not worth the paper they used to print it. It could be written in Chinese and even non-Chinese speakers would obtain as much knowledge by reading it.
But seriously, the entire user manual is 29 pages long. Not one page actually covers how to program the radio. Thankfully YouTube exists and many others before me figured it all out and shared their knowledge.
Ease of Programming
The UV-82 offers 182 different channels which can be programmed (once you figure out how to program them). Unfortunately, Baofeng (in their infinite wisdom) pre-programmed 20 channels (1-21). As you can’t edit a pre-programmed channel, you’ll need to delete these which can be done one-by-one in the menu.
While I believe it might be a daunting task for any brand new ham (or soon-to-be brand new ham) to sit down with an HT, User Manual and Repeater Directory and successfully program the radio. The Baofeng (unfortunately) really makes it impossible. This is part of what I was talking about during the Practical Amateur Radio Podcast (episode 70). As I’ve always recommended the Nifty Ham Radio Guides for ALL radios, I think it is a must have for the Baofeng.
Alternatively, if the UV-82 is going to be your primary hand-held and you’ll want/need to reprogram often. I would highly recommend purchasing the programming software and cable from RT Systems. While I don’t plan to purchase the the cable/software for the Baofeng, I do own the software and cables for all my other rigs.
While I’ve not discussed each and every feature/benefit of the Baofeng UV-82 in this blog article. I’ve identified a few key areas which I’ve discovered and most importantly have feedback/opinions on regarding. More importantly, as I’ve previously mentioned…I don’t plan to heavily use this radio. But having said that, I also wouldn’t have an issue with clipping it to my belt and heading down the trail either.
The opinions within our hobby of what makes a great first radio for a beginning ham are strong. Some are pro the HT and some are against the HT. If you are just starting out in our wonderful hobby, on a tight budget and looking to pickup a radio which won’t break the budget and allow you to enjoy the hobby…then I certainly recommend the Baofeng UV-82. After all, the package contains everything (transceiver, antenna and power source) you’ll need to get on the air. Get your ham radio license and join the fun of the worlds best hobby.
Until next time…

Hello fellow hams. Yes it’s been awhile since anything spewed from my blog site. I’ve just not had time in recent months to do much of anything related to the hobby of amateur radio. But once again I am easing back in as I hear it calling my name (or my callsign)…..
Like most hams, I have more radios that I truly know what to do with. This is especially true in the hand-held or HT department. I own a few Yaesu HT’s and one ICOM D-STAR HT. As I only have two hands…..anyway
Yea, PARP is also going to return from the ashes and in looking at some of the topics I want to cover in the next several months I decided to journey to a place I’ve never been. Yep…that is the world of the Chinese inexpensive hand-held radio.
As PARP is 100% commercial free and fully self-funded by the bank of KDØBIK (and Mrs. KDØBIK) I have always done my best to only make purchases for things that I believe I’ll actually use when it comes to podcast topics.
If you look through my ham shack you’ll find lots of ham radio goodies. I would estimate a solid 95% of all my gear has been purchased in person at my local HRO (Ham Radio Outlet). For us hams in the greater Denver area, we are very fortunate to have a candy store here. I’ve always realized the importance of “buying local” whenever possible. But as I say again, PARP has no sponsors and I really didn’t think I needed yet another HT. So I began comparing prices.
This price comparison exercise eventually led me to Amazon and eventually led me to an older Baofeng UV5RA 2m/70cm dual-band HT which comes complete with charging stand and hands-free kit for a whopping $26.06. With free two-day shipping via my Amazon Prime membership and an almost $3.00 credit I had floating around, the total purchase price was just too low to pass up.
So if you are in the market for another HT, on a limited budget and/or don’t mind the fact this is an older model…then check out this Amazon link.
As I write this early on Friday morning, my new Baofeng UV5RA will arrive sometime on Saturday. I’ll spend some time with it and as I said will most likely discuss this and other inexpensive Chinese HT’s on a future episode of PARP.
Bottom line, this new HT won’t replace any of my other models. My Yaesu VX8x is my main “go to” HT. But I’ll most likely program a few local repeaters along with the NOAA weather frequency and just leave this Baofeng at my office. This way as I watch those summer afternoon storms build, I can also monitor the weather info and perhaps some of our fellow storm chasers.
I’ll report back my findings and experiences at a later time…
Until next time…

Both the Baofeng UV-5R handheld UHF/VHF radio and the Sainsonic AP510 APRS tracker come with interface cables with pirated chips. These are clones of Prolific USB/serial chips. Since Prolific has taken measures against this, only old drivers will work with them. That means that one has to stop automatic driver updates as explained on the Miklor site for the Baofeng UV-5R. The same is true for the AP510. This is a nuisance.
I got tired of this and got myself some USB/serial modules from Ebay based on the CP2102 chip instead. The cost was US $1.43 a piece so it should be affordable for anyone. I also got some clear heat shrinkable tube.
It wasn’t too hard to follow the instructions on the Miklor site. I ended up replacing the chip in the original Baofeng serial cable. I’m a hardware guy so I think it is a shame not to see the three LEDs for power, rx, and tx so I used my Dremel to make a 12×12 mm cut-out in the original case, and then I closed it by using transparent shrinkable tube. For a picture, see the top of the first image.
If it doesn’t work the first time, exchange the rx and tx connections and see if that works better. According to this site, the boards can be marked just opposite of what you might think.
The Sainsonic AP510 APRS unit has a cable that on first sight just looks like a standard USB cable, but it also contains such a chip. Here I made a completely new cable without any case. It is important that 5 Volts also passes through as this is used for charging. The pinout can be found on the site of DJ7OO (use Google translate if needed). I enclosed the board in shrinkable tube which is transparent enough for the LEDs to shine through as seen in the bottom of the first image. The board with the fake chip is found in the middle.
