The QSO with ON5DN in Rune’s shack would be the only one I made as SM/PA2BX. As I reported in a previous post I packed small and took a Chinese made crystal controlled, direct conversion trx with me. Just for fun and just to try out if you could make some QSOs with it at all.

Before I left Taiwan I tested it in the shack and there was indeed some signal coming out of it. But not the 3 Watts as advertised. Actually not much at all. In fact, barely noticeable on my power meter. And I’m lying here: not noticeable at all on my power meter. But I could hear a lot of Japanese stations on both 20 and 40 meters and I could hear my own signal S9+60 dB on my big rigs in the shack using only a wet noodle. Well, if not QRP then maybe QRPp. Or QRPpp. Or QRPpppppp. I didn’t expect a lot power from a single D802 transistor anyway.

So when we arrived in the small town of Rättvik, in Dalarna County I took out my small box and within 15 minutes I was “on air”. Enjoy with me the beautiful backdrop of my temporary, outdoor shack.Reception was good and I heard most of Europe on 40 and 20 meters by juggling between four different crystals and two end-fed half wave antennas. But my CQs went unanswered and answering the CQs of the strongest stations also didn’t yield a QSO. I didn’t mind, honestly. I had a lot of fun just listening and taking code, something I haven’t had time for in the last 18 months. And what really impressed me was the direct conversion receiver. Even more impressed when I heard a station from the US calling CQ.
Compared to Asia the bands in Europe are much more fun. They are crowded and you can hear many different modes any time of the day. In Asia there aren’t so many hams to begin with and during weekdays most of them work (Japanese retirees being a notable exception). On the weekends it gets busier, but then I have to work. Tough luck, so I was happy to get a good dose of ham radio in Sweden.

So, if you are thinking of buying a Chinese QRP CW kit of off eBay, then prepare yourself for being either surprised, or disappointed. The kit I bought was easy to assemble (surprise), received better than expected (surprise), but lacked the power for a proper QSO (disappointment).

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. 

Initial Thoughts

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. 

Case Quality

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. 

Screen

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. 

User manual

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. 

In Summary

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…

For the past several months I have been beaconing overnight on 630m WSPR mode. I've been using a new transverter designed by Roger Croft (VK4YB) and Ralph Loveday, in Queensland, Australia. One unit was sent to me for beta testing and I have been hammering it as hard as I can ever since setting it up in the spring ... no problems have been experienced after several months of 12 hour nightly beaconing punishment. Nightly signal reports often range from Hawaii / Alaska and eastward to New England ... all during the 'not so good' summer band conditions.

Now that beta testing is complete, production units are now ready for distribution from Monitor Sensors, a family environmental-sensor manufacturing company of which Roger is Governing Director.

The introduction of the VK4YB 630m Transverter presents another new option for those wishing to get on the band, or in the case of American amateurs, to get prepared for the band ... soon expected to be implemented in the U.S.

When I first started using the test unit provided, I was immediately impressed with how simple it was to set up and to get operational. It sits inconspicuously beside the main station's transceiver, taking up less space than the typical station speaker unit.

One usually associates 'transverter' operation with a rat's-nest of cabling or re-cabling to accommodate the new addition. The transverter arrived with all necessary cabling, even a nice Anderson power pole connector to connect the user-supplied 12V power source. A second pair of 12V contacts is also available for sharing with other station needs. One feature that I quickly appreciated was the dual RCA jack on the rear panel for controlling the transverter's PTT keying line. With my transceiver's PTT line already being used for another purpose, it was simply a matter of plugging-in (cable supplied) and sharing the line with the second jack ... no need for unplugging or using an external adapter to split the PTT line. Switching from 630m to normal HF operation is simply a matter of turning the transverter 'off' ... all HF operations are back to normal with antenna routing taken care of. There appears to be a lot of thoughtful engineering packed into this little box.


A look under the hood shows a well-planned and efficient use of space as seen in this pre-production prototype shown below. If Collins Radio were to manufacture a 630m transverter for the military, I can't imagine it being any better than this!

prototype board under test

Although rated at 50W output, my transverter produces ~ 70W output when run at 12.6 volts. More output can be realized at higher voltage, up to as much as 16 volts. Power is generated with six carefully-matched Lateral MOSFETS, three aside, in a parallel / push-pull configuration.

"... we carefully match the FETs into three pairs. Each pair is matched to its opposite number but the pairs are chosen so 2 have low gain, 2 have mid gain and 2 have high gain. This improves the IPs and also the harmonics. With matched FETs we are getting the 2nd harmonic at typically -60dB. That's 10dB better than the stringent FCC requirement." 

Roger's unit is running at 16 volts and produces 90W output, with his 630m WSPR signal being the one most often heard in North America from down under.

The transverter's multi-colored screen combines with a multi-function menu, allowing a visual on-screen display of numerous parameters such as RF output power, DC supply voltage and current draw, SWR, exciter drive power, heatsink temperature, graphic SWR display and various warning screens.

The transverter requires 3-5 watts of 160m drive from the station transceiver for full output power. Built-in safety circuits prevent overdrive from causing any damage. Similarly, transmitting into a high SWR or with no antenna connected is no cause for concern. Temperature sensors will trigger shutdown should the heatsink rise above 100 degrees C. Software also prevents out-of-band transmission.

This is a microprocessor controlled linear-transverter. This means that operating system software can be readily updated (via the supplied micro USB cable) as new features are implemented. It also means that any mode your transceiver is capable of operating on can be produced on 630m. At present, the most popular modes on the band are WSPR, CW and JT9 but I suspect this order may change once the band is opened up in the U.S.


A shortened eight-page Operator's Manual can be downloaded from the Monitor Sensors web site but units will ship with a more comprehensive 22-page manual. For more information regarding pricing and shipping, please contact Monitor Sensors here. For technical questions, please contact Roger here.
