I was first introduced to D-Star some twelve years or so ago.  I purchased the ICOM IC-92AD hand-held and managed to get setup on one of the local D-Star repeaters.  Being one who (at the time) preferred all things HF, my D-Star activities were almost non-existent.  But it was fun to tinker and learn.

Some time passed and I experimented with various DVAP type devices that came onto the market.  I preferred using these to the local repeater, since I could connect into reflectors around the world and share in all the fun of digital radio.

Around the early 2016 timeframe, I purchased the Hardened Power DHAP Mini Mega Self Powered Enclosure along with a Raspberry Pi 3 and the DVMEGA Dualband add-on for the Pi.  The DHAP case is a 3-D printed plastic.

Inside there’s plenty of room for the Raspberry Pi, the DVMEGA and four rechargeable batteries.

I setup the Raspberry Pi with a popular image at the time from the Maryland D-Star group.  As I have never claimed to be a Raspberry Pi expert, even though I do own three devices.  One being an ADS-B aircraft tracker and second which has been running SETI@home and then the third running the Maryland D-Star setup.

Anyway, the Maryland D-Star image was easy to setup and at the time (2016) the group was active.  They had a website which contained more knowledge needed to setup the Pi and a very helpful forum community.  I could fire up my DHAP and via my radio connect/disconnect reflectors all around the world, reboot or shutdown the Pi.  It was all very cool.

Burnout

When the burnout occurred in late 2016, I wasn’t doing any form of operating and as a result I shut down the D-Star Pi and placed it (along with the IC-92) in a closet.  It sat there until just about two weeks ago when (like many of you) found myself bored out of my skull from the self-isolation COVID-19 routine.  I decided this was a project that might take my mind off the events of the world and might even help rekindle some of my amateur radio interests.

Power Up

After being sat idle for over three years, everything needed a good charge.  Surprisingly my ICOM batteries all came back to life and even the DHAP powered on just fine.  Everything worked (just as it did when I shut it down) but I figured at the very least I needed to update the software.  That’s when I realized the Maryland D-Star Pi was no more.

Pi-Star

While everything worked (best I could tell), in my hunt for what happened to the Maryland group, I discovered Pi-Star.  The Pi-Star group is an active group and appears to be the best thing since sliced bread when it comes to all things D-Star hotspots.  So I downloaded their latest and greatest image (4.1.0), installed it onto an empty SD card and began noodling around.

Of course “Noodling” around is much like driving around trying to find something without actually stopping to ask for directions.  The end result left me sort of frustrated and wondering if I should just go back to using the old Maryland setup.  At least it worked…for now.  But it’s not like I don’t have time or the mental capacity to figure this out.  So, diving head first into the forums I began to find the answers I needed and more importantly, I knew once I had everything working…it would be a much better setup.

All the Pre-requisites

As my DVMEGA was several years old, one of the first things required was to update the firmware so it could take advantage of all the features in Pi-Star.  This wasn’t as straight forward as I had hoped it would be.  It required some risky soldering of a short wire so the firmware of the DVMEGA could be updated.  I found all the documentation required for performing this risky step located here.  Well…almost!

With soldering iron, wire and some solder in hand, I completed the risky step and proceeded to update the firmware.  However, each time I attempted to perform the update it failed.  What have I done?  Did I ruin the DVMEGA?  I decided to go to bed and then take another stab at it the next day.

With a strong cup of coffee in hand, I proceeded to double-check all my work.  I felt confident in the soldering job, so hardware was all GO!  I then looked at it from the software perspective.  I decided to try using an older version of Pi-Star to rule out some issue with the latest version.

BINGO!

Once I rolled back to version 3.4.17 (from earlier this year), the process of updating the DVMEGA firmware worked just as it should.  In just a few minutes I had managed to update the firmware of my DVMEGA board from 2.19 to the latest 3.26.

More Frustration

With the DVMEGA updated to 3.26 and my Pi running Pi-Star 4.1.0, I began digging into the programming requirements of my radio.  For the life of me, I couldn’t figure  out how I needed to setup the radio so I could still control the system from my handheld.  After a bit of swearing and more digging in the forums, I discovered a fairly significant difference between how the radio needed to be setup from what was required with the Maryland D-Star setup.

I got there in the end

Yep, all appears to be working perfect.  I can easily connect and disconnect from any reflector I have programmed into my IC-92 from anywhere in the house.  While I tend to leave the setup in my shack (basement man cave) connected via Ethernet cable, I also can move the device around the house and use wi-fi.

From within my QTH the device is fully self-contained.  I can run it off the batteries and wi-fi and have coverage anywhere within the house (or even from back deck) should I choose.

Next Steps

I do have a few additional setup steps which I plan to experiment with in the coming days.  With the old Maryland setup I had my smartphone hotspot configured which would allow me to take this mobile.  Pending I had good broadband coverage, I could activate my hotspot, turn on the DHAP and place it all in the car for mobile ops.

Want more info on Pi-Star?

Your first stop needs to be the Pi-Star homepage.  From there you can join the forums, download the software and learn everything you need to know about Pi-Star.  I also found another great source of information on the Amateur Radio Notes blog site which is managed by Toshen, KEOFHS.  He’s a fellow Coloradoan living in Lyons.

Well I think that just about does it for this posting.  I wish you and your family a very Blessed Easter weekend (if you celebrate).  I’ll return soon with another update.

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…

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…

If you operate your Elecraft KX3 in a portable environment (and perhaps even if you don’t) there are a few must-have add-ons which really help protect your KX3.  You are probably already aware of the popular KX3 KX Endplates and KX Cover available from Scott, AK6Q and his Gems Products website.  I received both as a Christmas present from my darling wife and love what they do for my KX3.

In addition to operating SSB phone via my KX3 on SOTA activations, I also enjoy grabbing my Buddipole a battery and heading outdoors for some picnic table portable operations in a park or really just about anywhere.  In this setting I typically bring along my laptop and operate PSK-31 or JT-65.  However, one thing I’ve noticed (and have been concerned about) is how the KX3 has the potential to heat up when running these digital modes (even at 5w or less).  This is especially evident in the warmer months of the year.

A few weeks ago I was browsing the KX3 Facebook page and learned about an add-on heat sink designed, built and sold by a fellow ham in Canada.  This OM’s name is Fred Meier, VE7fmn.  I contacted Fred via email and he quickly provided a detailed response on how he designed his KX3 heat sink and provided cost and availability information.  While I did find one other heat sink being marketed for the KX3, I believe Fred’s version is more effective at dissipating the heat from the KX3 and it looks great while doing it.

Here’s what Fred’s KX3 heat sink looks like installed on my KX3.

Fred’s KX3 heat sink is well built and designed to be durable.  The fins on the heat sink are not going to bend or break off and only adds an additional 8 ounces of weight to the KX3. 

I’ve conducted a few tests while in the shack and had the KX3 running PSK-31 and JT-65 at 10w and never received the overheat warning.  I couldn’t run above 5 watts inside or outside the shack without the heat sink installed.  I’ve yet to test the KX3 with heat sink installed outside in a portable setting, but I’m confident I will not have any issues.  If you would care to read another review of VE7fmn’s heat sink, please go here.

As I’ve stated, I love operating portable with my KX3 and I’m Happy, Happy, Happy to have this wonderful add-on to help keep my KX3 Cool, Cool, Cool.

Until next time…

If you own a smartphone and/or tablet device and use any of the amateur radio related apps designed for these devices, I would like to hear from you.  I’m conducting research for an upcoming episode of the Practical Amateur Radio Podcast (PARP) and would like to know what apps you are using, how you use them and how they work for you. 

Please contact me via the email address listed on my QRZ page.  Thank you!

I’ve owned my Raspberry Pi for a while now.  I purchased it around the time they were first introduced (early 2012).  Not having a lot of knowledge in the Linux OS, the most I ever really did with it was set it up and play around with it.  However, my reason for purchasing the RPI was to some how use it for amateur radio purposes. 

As I have mentioned before on my blog, I also own a D-STAR Digital Access Point Dongle (DVAP).  I purchased it in 2011 and had been using it connected to an older Windows XP machine.  I wrote a “first look” post as well as one where I was experimenting on the DVAP range away from my QTH.   However, in following my own advice given in my podcast, The Practical Amateur Radio Podcast episode 64 about the Microsoft Windows XP End of Life, I decided it was time to explore how the DVAP might be used with the Raspberry Pi.

In most situations, Google truly is your friend.  Just doing a simple Google search for DVAP and Raspberry Pi led me to more information than I had time to read.  However, the very first search result happened to provide all the information I needed to setup my Raspberry Pi to work with my DVAP dongle.  Special thanks to Bill, AB4BJ who had blogged about his experience in setting up his Pi for DVAP purposes. 

If you have a Raspberry Pi, a DVAP Dongle and a D-STAR radio sitting around your ham shack, it’s very easy to set it all up just as I have done.  In the below picture, I have my ICOM ID92-AD, the DVAP Dongle and the Raspberry Pi setup.  Once configured, the Raspberry Pi will function stand-alone (without keyboard, mouse and monitor).  I can access the RPI via VNC from my iPad if needed. 

Raspberry Pi running Debian Linux and the DVAPNODE and IRCDDB software.  DVAP is connected to REF001A in Aurora, Illinois.  Screenshot from iPad VNC session.

For now, my setup will remain in my ham shack.  I know many build this setup for mobile/portable use.  At the present time I do not have wireless capabilities for the RPI.  I also want to see just how stable this setup is before making any additional changes.   I was pleased to wake up this morning and find the RPI was still running and the OS was stable.  Time will tell…

Until next time…
