Ham Radio Gamification

Posted on by — 3 Comments ↓

Setting operating goals has been useful for me in ham radio. They often provided a reason or incentive for me to get on the air and make some contacts. I followed the typical award sequence of Worked All States (WAS), Worked All Continents (WAC), DX Century Club (DXCC), and so forth. I wrote about it here: Pursue Radio Operating Goals.

Gamification

Over time, I’ve come to realize that some amateur radio activities include the elements of gamification. Gamification is a hot topic in user interface design, online learning, and other computer-based systems. The basic idea is to incorporate gaming techniques into activities to increase user engagement. From Wikipedia:

Gamification techniques are intended to leverage people’s natural desires for socializing, learning, mastery, competition, achievement, status, self-expression, altruism, or closure, or simply their response to the framing of a situation as game or play.

Gamification commonly uses these elements (also from Wikipedia):

Game design elements are the basic building blocks of gamification applications. Among these typical game design elements, are points, badges, leader-boards, performance graphs, meaningful stories, avatars, and teammates.

This article discusses some of the principles involved and Dennis/AD6DM wrote this piece on the topic: The Gamification of Ham Radio.

Summits On The Air

I first became aware of this topic after I became involved in Summits On The Air (SOTA). Before SOTA was a thing, I was often found on the top of some summit making radio contacts. So when SOTA was established in Colorado (W0C), I thought “this is interesting but I am already doing it.” It did strike my fancy enough that I started submitting logs into the SOTA database. Oh, guess what, many of my mountaintop operations were the first activation for SOTA. How about that? I am the first. I win. I have bragging rights, or something.

Soon I was accumulating SOTA activator and chaser points. My first objective was to qualify for the 100-point activator certificate. (SOTA has many certificates and awards.) Achieving 100 points took me about 15 activations, so it is not too difficult but does represent an accomplishment. It did not take very long to do this and soon I was focused on 1000 points for the coveted Mountain Goat award. That goal took several years to complete, but I got it done. I decided to only use the VHF/UHF bands for the Mountain Goat award, so that was my little personal twist on that accomplishment.

We can clearly see that the SOTA program has these elements of gamification: points, badges (certificates/awards), and leaderboards. For me, the leaderboard is the Activator Role of Honour, with the Colorado (W0C) Association selected:

At the moment, I am #12 on the list. I do not aspire to be at the top of the list but I do want to be on the list, somewhere above the 1000 mark. I also like to see how my fellow W0C SOTA activators have been doing. For example, it has been fun to watch Szymon/WV0X go from zero activator points to over 1800 in a short period of time. Also, Gary/W0MNA and Martha/W0ERI are a couple from Kansas (no SOTA summits in the state) that have both made it to Mountain Goat. Not an easy accomplishment. It is cool to see that we have 19 Mountain Goats in the association and more on their way. Pretty good!

SOTA does not specifically have any teams formed as part of the program but the camaraderie of W0C is essentially a team. We share information about various summits and encourage each other when new goals are achieved. Sometimes groups of activators get together for a joint activation. (Most areas that have significant SOTA activity also have this community/team effect.)

Parks On The Air

Recently, I have become involved with Parks On The Air (POTA), which also has gamification built into it. POTA has the advantage of parks being virtually everywhere. (Unlike SOTA summits, Kansas has parks to activate.) As Joyce/K0JJW and I have traveled around the country, POTA has been a satisfying activity to include in our plans.

POTA has many different award schemes, too many to mention here. I pulled up my awards page to see what I have qualified for:

The objective I have set for POTA is to activate all the parks in Colorado. I want to visit them anyway, so this is a good opportunity to blend ham radio with our travel plans. There are 187 POTA parks in Colorado, so this is going to take a while to complete.

Implications

Gamification can be used to make ham radio activity more fun and to more fully engage the participants. Traditional radio contesting is clearly a competition and has the elements of keeping score, having leaderboards (after the contest) and having teammates. However, most contests provide painfully slow feedback. The official results may not be posted until 6 months later. (The 3830 Scores website was created to bypass this delay by sharing scores immediately.) Contesting is obviously a game, so where’s the gamification?  [Update: Justin/K5EM pointed out there are contests that have online live scoring: contest.run and contestonlinescore.com ]

Perhaps your radio club (or just your group of ham friends) can use gamification to have fun. You could leverage programs like SOTA and POTA to create a club activity. Pursue a club goal (activate 50 parks or summits this year), a friendly competition, whatever. POTA lets you activate with a club call while still providing credit for the operator, so that opens up some possibilities.

If you are getting stale in your ham radio operating, perhaps one of these gamified programs would be good motivation for you. It could be SOTA or POTA (both include chasing, so you can do it from home), or maybe some other program out there.

Those are my thoughts. What do you think?

Ham Radio, Chess and Model Railroading

Posted on by — 1 Comment ↓

Every once in a while, I look at the number of licensed radio amateurs in the US and ponder how ham radio participation rates compare with other hobby activities. Take a look at this post from 2005: Some Amateur Radio Statistics and this one from 2015: Ten Year Trends in US Ham Licenses.

The latest number of FCC amateur radio licenses (March 2018, from ah0a.org) is 749,711 (Novice: 8847; Technician: 379,735; General: 174,478; Advanced: 41,153; Extra: 145,498)

The population of the United States (2018 estimate) is 325 million which means that FCC amateur radio licensees are 0.2% of the US population. (Yes, this number surely overstates the number of active radio hams.) From the 2017 Annual Report, ARRL membership is 159,070, which is a decline of 3% from the previous year, apparently associated with a recent dues increase. There is a slight time skew in the numbers but this means that ARRL membership is ~21% of the FCC licensees. This represents about a 2 point decline from the same calculation for 2005. Not a good trend.

It is interesting and maybe even useful to compare these numbers to other activities we are familiar with in the US.

Fishing

I stumbled across an in-depth analysis of sportfishing (basically all kinds of recreational fishing) by the American Sportfishing Association.  This report on US Angler Participation says that 49 million people in the US participate in fishing, or 15% of the US population. Frankly, that number seems a bit high but let’s just go with it. Perhaps what’s more interesting is their analysis of renewal rates for fishing licenses and potential reasons for why people start and stop fishing. Oh, guess what? Young people are not pursuing fishing at the same rate as adults so there is concern about the future of the sport. Browse through the website and you will find reasonably good data on the state of fishing in the US.

Outdoor Sports

The Outdoor Industry Association publishes data on a wide variety of sports ranging from bicycling to birdwatching. According to their numbers, every activity they track has a larger percent of the US population than the FCC amateur radio license number.  A very popular outdoor activity is bicycling, with a participation rate of 24%. Other significant sports listed include camping (21%), running (21%), hunting (6%) and downhill skiing (4%). Even birdwatching comes in at 3% and snowshoeing is listed as 1%.  This report also analyzes participation rates, motivations and trends by race, age and other factors. Good stuff.

Chess

I came across a web page that asks the question “how many people play chess?” This caught my eye because I think there are significant similarities between the game of chess and amateur radio. The answer: no one knows.

One study claims that 15% of the US population plays chess at least once per year.  This would be close to 50 million players and put it in the same participation class as camping or bicycling. That just seems too high…I can name quite a few of my friends and family that camp and bike. I can’t name hardly any that play chess regularly.

The US Chess Federation has 85,000 members, who are presumably actively involved in chess (for the most part). There are probably many times more people that play chess casually. A wild and generous guess of 10 times or 850,000 players would still only be 0.26% of the US population.

The chess community has many effective programs to help children get started in the game. This is probably a real strength for that community. However, I noticed several discussions in online forums lamenting the fact that children tend to drop the game in their teen years. Also, Sports Illustrated just published an article about how chess has always been dominated by men with women making limited gains in participation.

Model Railroading

Then someone on reddit asked why ham radio magazines have disappeared but model railroading magazines are quite available at the local bookstore. Now that is an interesting comparison. Model railroading is a well-established hobby that many people pursue for enjoyment. It is a bit “old school” with a strong hands-on “maker” aspect to it. It has also has seen the impact of newer technology, especially digital electronics. In terms of alternative activities, it is seeing competition from radio-controlled cars and aircraft.

This online forum puts the number of US model train hobbyists in the range of 150,000 to 300,000, but without much in the way of hard numbers (just anecdotal evidence).  One person argued that the number is more like 1 million hobbyists. This web site makes the claim (without references):

Today there are a half million model railroaders and toy train hobbyists in the US and Canada!

But many model railroaders see challenges ahead. This Wall Street Journal article discusses how the demographics of the railroader population are changing: End of the Line for Model Trains? Aging Hobbyists Trundle On

This web site also discusses the trends in model railroading. I found this quote to be relevant:

This hobby (as well as a lot of other markets) is currently dominated by the baby boom generation. They will be dwindling in numbers over the next ten years, and the generations behind them just don’t have the numbers to fill in unless there is a significant boom of interest in model trains.

One commenter suggests there are 1 million model railroaders in the US.

Analysis

First, I am struck by the number of different hobby and sports activities available to us. From a historical perspective, North Americans have significant leisure time and a multitude of activities to choose from. Some of those are “mainstream” in the sense that most people are aware of them and many people do them (examples: fishing, bicycling, running). Other activities fall into a niche (< 1% of the US population) but still have vibrant communities that pursue them with gusto (examples: chess, amateur radio, model railroading). The participation rate for Chess may actually be higher than 1% of the population…I’m really not sure…but it looks more like a niche activity than a mainstream hobby.

The mainstream activities tend to have access to good data on participation in the sport or hobby while the niche activities tend to be lacking reliable data. It seems that the more popular activities have a industry association or member organization with sufficient resources to pursue obtaining participation data and maintaining it over time. The information available concerning sportfishing and outdoor activities was pretty impressive. Chess, amateur radio and model railroading…not so much. If you are worried about the health of a hobby or sport, the first step is to have accurate data. (I recently heard that ARRL Headquarters is pursuing this. I certainly hope so.)

Participants in many of these activities express concern about the demographics of their communities. There are lots of comments on web sites about needing to attract younger participants for the future of the hobby, along with comments about how kids don’t seem to be interested. The big concern was getting kids involved but there are also issues of low participation by women. Certainly, we hear these same concerns in the amateur radio community.

One big takeaway is that amateur radio is not the only community that is concerned about growth. I’d really like to hear from radio amateurs that are active in chess and model railroading, to compare and contrast their experiences.

VHF FM: The Utility Mode

Posted on by — 1 Comment ↓

Handheld transceiver I’ve been referring to the VHF FM as the utility mode for quite a while now. I picked this up from Gary Pearce/KN4AQ when I inherited the FM column from CQ VHF magazine (no longer being published). Gary recently filled me in on the origin of this term, which he captured in his first FM column for CQ VHF.

Gary describes how he got hooked on VHF operating, especially 2m FM:

I’ve been a ham since 1965 (age 15).  Today, I have an Extra class license, and I operate some HF (mostly SSB and digital, with cw limited to occasional bouts at Field Day).  But since my first days as a Novice with a Heathkit Twoer, I’ve been a VHFer.  I went through the 2 and 6 meter AM days with a Heath Seneca and Utica 650, and then SSB with a Gonset Sidewinder and Hallicrafter HA-2 transverter.  But what really flipped my switch as an early ham was an old, single-channel Motorola 80D on 146.94 simplex, installed in the car of a teenage friend’s father.  For you newer hams, this is an exercise in nostalgia that I don’t have space here to explain – I wish I could.  I will note that the Motorola 80D was an FM radio that began life in a police car or taxi cab somewhere.  It was a huge, heavy, all-tube radio that sat in the trunk and improved traction on the ice.  Below the dash was a control head with volume, squelch, and the microphone and speaker.

It wasn’t long before I learned about repeaters, which enhanced the FM experience immeasurably (all four of them in the Chicago area at the time).  My interest in VHF SSB waned…Getting involved in a local repeater group felt comfortable – this was someplace where I could really participate.

But then things shifted as time passed. Gary wrote:

While I wasn’t looking, FM became just another mode.  At least that’s the consensus I got from some of the guys who have been doing Amateur Radio publishing a lot longer than I have…

Some columns devoted to sub-sets of Amateur Radio have lasted for decades.  VHF-UHF is one.  That’s the weak-signal side of VHF, not the FM side.  Digital modes go through enough reincarnations to keep interest up.  DX, contesting, QRP, holding their own.

But not FM/Repeaters?  QST editor Steve Ford, WB8IMY, suggested why, and gave me the idea for this column’s “Utility Mode” tag line.  He said, “Our research has shown that while FM users comprise a very large portion of the amateur community, the majority tend to perceive their FM activity more as a ‘utility’ function rather than a hobby.”

VHF FM is arguably the most common mode used in amateur radio. (Can I back that up with reliable data? Not sure, but I’m pretty sure it’s true.) I do see where it fits into the concept of a utility function or utility mode. Think about the electrical system in your house (a utility). For the most part, you just plug things in and use it but you probably don’t consider yourself a 120 VAC hobbyist. Well, a few of you might but that’s another issue. VHF FM is a lot like that…most hams have it and they just use it without too much consideration. Push the button and it works.

But that definition is a little bit derogatory…VHF FM is just there and no one appreciates it. The Eeyore of ham radio modes.

Another definition of utility (as an adjective) is:

Utility: having or made for a number of useful or practical purposes rather than a single, specialized one:

a utility knife.

 

This fits my perception of VHF FM: very useful for many things. Whether you are providing communications for a bike race, handling talk-in for a local hamfest, working the ISS, chatting across town while mobile, the first choice is likely to be 2m (or 70 cm) FM.

And that’s why I’ve always been a VHF FM enthusiast: there are so many things you can do with it. Just use your imagination.

Amateur Radio: Narrowband Communications in a Broadband World

Posted on by — 4 Comments ↓

5g graphicFor my day job in the test and measurement industry, I get involved in measurement solutions for wireless communications. Right now, the big technology wave that is about to hit is known as 5G (fifth generation wireless). Your mobile smartphone probably does 4G or LTE as well as the older 3G digital mobile standards. For more detail on LTE, see ExtremeTech explains: What is LTE?

5G will be the next cool thing with early rollouts planned for 2018. The design goals of 5G are very aggressive, with maximum download speeds of up to 20Gb/s. (See what I did there: I used the words “up to”, so don’t expect this performance under all conditions.) The actual user experience has yet to play out but we can assume that 5G is going to be blazing fast. For more details see: Everything You Need to Know About 5G. To achieve these high bandwidths, 5G will use spectrum at higher frequencies. Move up in frequency and you inherently get more spectrum. The FCC recently allocated 11 GHz of new spectrum for 5G, including allocations at 28 GHz, 37 GHz, 39 GHz and 64-71 GHz: FCC 5G spectrum allocation demands 3 breakthrough innovations . Yes, those frequencies are GHz with a G…that’s a lot of cycles per second.

Amateur Radio

So my day job is focused on wider bandwidths and higher frequencies. Then I go home and play amateur radio which is a narrowband, low frequency activity. The heart of ham radio operation is on the HF bands, 3 to 30 MHz, almost DC by 5G standards. Many of us enjoy VHF and UHF but even then most of the activity is centered on 50 MHz, 144 MHz, maybe 432 MHz. I recently started using 1.2 GHz for Summits On The Air, so that at least gets me into the GHz-with-a-G category.

Not only does ham radio stay on the low end of the frequency range, we also use low bandwidth. The typical phone emission on the HF bands is a 3-kHz wide SSB signal. That’s kHz with a k. As we go higher in frequency, some of our signals are “wideband” such as a 16-kHz wide FM signal on the 2m band. In terms of digital modes, AX.25 packet radio and APRS typically use 1200 baud data rates but sometimes we go with a “super-fast” 9600 transmission mode. (Not really.)

CW is still a very popular narrowband mode with bandwidths around 200 Hz, depending on Morse code operating speed. Lately, the trend has been to go even narrower in bandwidth to keep the noise out and operate at amazingly low signal-to-noise ratios. Some of the WSJT modes use bandwidths in the range of 4 to 50 Hz.

There are some good reasons that amateur radio remains narrowband. The two most important are:

  1. We love the ionosphere and what it does for radio propagation. The HF bands are great for making radio signals go around the world but they are narrow spectrum. For example, the 20m band is 350 kHz wide, going from 14.000 to 14.350 MHz. Operation is restricted to narrowband modes, else we’d use up the entire band with just a few signals.
  2. We just want to make the contact (and maybe talk a bit). For the most part, radio hams are just trying to make the contact. This is most pronounced during a DX pileup or during a contest when you’ll hear short exchanges that provide just the minimal amount of information. Some of us like to talk…rag chew…but that can be accomplished with narrowband (SSB) modulation with no problem. It seems that narrowband signals suit our needs. I suppose it would be handy from time to time to be able to send a 3 MB jpg file to someone I am working on 20m but that’s not the main focus of a radio contact.

Of course, not all amateur radio operation is below 1 GHz. There’s always someone messing around at microwave and millimeter wave frequencies. I’ve done some mountaintop operating at 10 GHz and achieved VUCC on that band. Recently, the ARRL announced a new distance record of 215 km on the 47 GHz band.

ICOM produced a D-STAR system at 1.2 GHz with a data rate of 128kbps, quite the improvement over AX.25 packet. However, adoption of this technology has been very limited and it remains a single-vendor solution. In fact, it may be a dead technology, hard to say.

There is significant work going on with High-Speed Multimedia (HSMM) Radio which repurposes commercially-available 802.11 (“WiFi”) access equipment.  Broadband-Hamnet is focused primarily on using 2.4 GHz band to create mesh wireless mesh networks. Amateur Radio Emergency Data Network (AREDN) is doing some interesting work, mostly on the 2.4 GHz and 5.8 GHz bands. The HamWAN site has lots of information about a 5.8 GHz network in the Puget Sound area. I just became aware of the Colorado Amateur Radio Broadband Network, in my neighborhood. The basic theme here is use commercial gear on adjacent ham bands…a common strategy for many VHF and higher ham radio systems.

Also worth mentioning is the FaradayRF work, currently aimed at creating a basic digital radio for the 33cm (902 MHz) amateur band. The raw data transfer rate is around 500 kbaud.

There are probably some other high-speed digital systems out there that I’ve missed but these are representative.

Infrastructure Rules

A critical factor in making LTE (and 5G) work is the huge investment in infrastructure by Verizon, AT&T and others. With cellular networks, the range of the radio transmission is limited to a few miles. One of the trends in the industry is toward smaller cells, so that more users can be supported at the highest bandwidths. With 5G moving up in frequency, small cells will become that much more important.

On the other hand, most amateur radio activity is “my radio talking to your radio” without any infrastructure in between. Most of us like the purity and simplicity of my station putting out electromagnetic waves to talk directly to fellow hams. In many cases, this simplicity and robustness has played well under emergency and disaster conditions.

FM (and digital voice) repeaters are a notable exception with the Big Box on the Hill retransmitting our radio signal. For decades now, FM repeaters have represented an infrastructure that individual hams and (more often) radio clubs put in place for use by the local ham community. There is a trend towards more infrastructure dependency in ham radio as repeaters are linked via the internet via IRLP, EchoLink and other systems.  (Some hams completely reject any kind of radio activity that relies on established infrastructure, often claiming that it is irrational, unethical or just plain wrong.)

One interesting area that is growing in popularity is the use of hotspots (low power access points) for the digital voice modes (D-STAR, DMR, Fusion, etc.) In this use model, the ham connects a hotspot to their internet connection and talks to anyone on the relevant ham network while walking around the house with a handheld transceiver. See the Brandmeister web site to see the extend of this activity. It strikes me that this is the same “small cell” trend that the mobile wireless providers are following. You want good handheld coverage? Stick a hotspot in your house.

Looking at ham radio and broadband communications, I summarize it like this:

  • The vast majority of ham radio activity is narrowband, for reasons described above.
  • There is some interesting ham radio work being done with broadband systems, mostly on 2.4 GHz and 5.8 GHz.
  • Commercially available broadband technology (LTE, 5G, and beyond) will continue to increase total network bandwidth and performance increasing the difference between commercial broadband and narrowband ham radio.

Implications

The reason for writing this article is that the amateur radio community needs to recognize and understand this increasing bandwidth gap. We like to talk about the cool and exciting stuff we do with wireless communications but we need to also appreciate how this is perceived by someone with an LTE phone in their pocket.  Just communicating with someone at a distance is no longer novel. After all, Amateur Radio is Not for Talking.

What do I conclude about this? Here’s a few options:

1. Don’t worry. We are all about narrowband and that’s good enough. This attitude might be sufficient as there are tons of fun stuff to do in this narrowband world. In terms of ham radio’s future, this implies that we need to expose newcomers to narrowband radio fun. We’ll need to get better at talking about how amateur radio makes sense in this broadband world.

2. Embrace commercially available broadband. Use it where it makes sense. This approach means that Part 97 remains mostly narrowband but we can make use of the ever-improving wired and wireless network infrastructure that is available to us.

3. Develop Part 97 ham radio broadband. I am initially a bit skeptical of this idea. How the heck does ham radio compete with the billions of dollars Verizon, AT&T and others poor into broadband wireless? But that may not be the right question.  Once again, I fall back to the universal purpose of amateur radio: To Have Fun Messing Around with Radios.  Can we have fun building out a broadband network? Heck yeah, that sounds like an interesting challenge. Would it be useful? Maybe. Emergency communications might be an appropriate focus and some hams are already working on that. Create a network that operates independent from the commercial internet and make it as resilient as possible. It doesn’t have to be at 5G speeds but it better be way faster than AX.25.

I think Option #3 is definitely worth considering. What do you think?

Is the Internet Destroying Amateur Radio?

Posted on by — 31 Comments ↓

How many times do you hear the comment “ham radio…do people still do that?” followed by the statement that “surely the internet has made ham radio obsolete.” For the most part, that misses the point about the use and attractiveness of amateur radio.

And yes, that is a click bait headline.

I’ve written before that Amateur Radio Is Not for Talking and that the Universal Purpose of Ham Radio is to have fun messing around with radios. One significant statistic is that the number of FCC amateur radio licensees remain at an all time high. Eventually, the demographics will likely catch up with us and this number will start to decline, but it hasn’t happened yet.

The internet has become a tool that is used to complement amateur radio, often in ways that we may not have predicted. Although there are plenty of “keep the internet out of amateur radio” folks in the hobby, there are many more that have found clever ways to make use of the internet. I view emerging technologies and technological innovation as unstoppable forces that will impact us whether we try to ignore them or not. Using that lens, let’s examine the impact of the internet on amateur radio.

Here are a few broad categories of impact:

1. Communication Pipe

The internet is often used to provide an additional mechanism for transporting ham radio communications. Obvious examples are VoIP systems such as EchoLink and IRLP. Also included in this category are digital voice systems that use the internet to connect radios together: D-STAR, Yaesu System Fusion, Brandmeister Network, DMR-MARC Network. WinLink is a global email system using ham radio. The core transport technology is the Internet Protocol Suite (TCP/IP) which is not limited to the public internet. Some ham radio organizations are implementing IP links using microwave gear on the amateur radio bands so they are independent of the internet.

Another application in this category is remote operation of ham stations. That is, use an internet connection to control a ham station at another location. Sometimes people refer to this as the Long Microphone Cord Model (or maybe I just made that up). Hams do this with their own private stations but there are also shared stations established by radio clubs and commercial vendors (see Remote Ham Radio). With community restrictions on external antennas being very common, having a remote station available is very attractive.

This has turned out to be quite disruptive because so much of ham radio operating depends on your location, which is generally determined by the location of the transmitter. But now you can have a person sitting in downtown Denver operating a transmitter that is in Fiji. Kind of confuses things a bit. Regulatory issues also come into play: that transmitter in Fiji is going to fall under Fiji regulation which usually means needing an amateur radio license issued by the local government. The day is coming when a DXpedition to a remote island will consist of a helicopter delivery of a remote radio box (with satellite link and self-deploying HF antenna) that is operated by someone sitting at home using their smartphone.

2. Reporting and Coordination

Ham radio operators also use the internet for spotting and reporting purposes. Spotting has been around for a long time, which basically means letting other hams know that a particular station is on the air and can be worked from a particular location. Hams have done this without the internet but the internet certainly allows for more efficiency. Or at least a lot more spots. DX Maps is a good example of a spotting web site that supports lists and mapping of spots.

Radio hams also use the internet for coordinating radio contacts. One of the most extreme examples is the use of pingjockey for arranging meteor scatter communications. Typically, two hams will connect on pingjockey and agree to try a meteor contact on a specific frequency, with specific timing, etc. This technique is easy to abuse, either intentionally or via sloppy operating habits, because you can inadvertently share the radio contact information via the internet. However, properly used, pingjockey is a wonderful tool that promotes meteor scatter operating. ON4KST operates an amateur radio chat website that enables a wide variety of online communication and coordination between hams.

The Reverse Beacon Network (RBN) is a network of radio receivers listening to the amateur bands and reporting what stations they hear. These stations are often referred to as CW Skimmers because they skim the CW information from the received signals. RBN began with decoding CW but now also supports RTTY. There’s no fundamental reason it couldn’t be extended to other modes, even voice modes, with sufficient computing power.

PSK Reporter is a similar reporting system which accumulates signal reports from HF digital stations. As the name implies, it was first focused on PSK31 but has expanded to include other digital modes.

Weak Signal Propagation Reporter (WSPR) is more advanced propagation reporting system that uses transceivers and advanced DSP techniques. The compressed protocol sends the transmitting station’s callsign, Maidenhead grid locator, and transmitter power in dBm. WSPR lights up the world with low power transmitters and measures HF propagation on all bands in real time. Very clever system.
These worldwide networks produce a very complete picture of available propagation and stations on the air. Some hams complain that “nobody tunes the dial” anymore because they just rely on the station of interest to be spotted. DX stations often have the experience of huge pileup as soon as they are spotted on one of the networks.

3. Logging and Confirmations

For decades, hams have been keeping their radio logs using a wide range of software that is available.  This is a handy way of keeping track of radio contacts and tracking progress towards operating awards. More recently, online systems have been developed to allow radio contacts to be confirmed electronically. That is, instead of exchanging QSL cards as confirmation of a radio contact, both hams submit their log information to a central server that records the radio contact. The ARRL offers the Logbook of The World (LoTW) which supports these awards: DXCC, WAS, VUCC and CQ WPX. The eQSL web site was the first online QSL site, offering electronic QSL card delivery and its own set of operating awards. Club Log is another online electronic logging system. The popular qrz.com web site has added a logbook feature to its set of features.

Electronic confirmation of radio contacts is a huge improvement for ham radio. While many of us still enjoy getting a paper QSL card, collecting QSLs for awards is a royal pain. Mailing QSL cards is expensive, takes time and often involves long delays.

Impact on Amateur Radio

Here’s my analysis of the situation: Categories 2 and 3 mostly represent a net positive influence on amateur radio. These are straight up information age applications that provide useful and quick updates about radio propagation and radio contacts. Yes, there is some downside in that many hams become dependent on them instead of doing it the old fashioned way: turn the big knob on the radio and listen. Not a big deal given the benefits.

Category 1 is more of an issue for me. The major effect is that it enables worldwide communication a lot easier while using ham radio. This is what causes many hams to say That’s Not Real Ham Radio when the internet is used to do so much of the work. Focusing on the actual radio wave propagation, there is really no comparison between working DX on the 15m band and making the same QSO with a UHF DMR handheld piped through the internet.  At this point, I try not to overthink the issue, dropping back to The Universal Purpose of Amateur Radio is to Have Fun Messing Around with Radios. So if chasing DX on 15m floats your boat, keep on doing it. If the DMR handheld provides enjoyment for you, I’m OK with that, too.

Perhaps more importantly, we can’t really stop the impact of new technology. Oh, I suppose the amateur radio community could petition the FCC to restrict Category 1 use of ham radio. There could be regulations that limit the use of the internet being interconnected with Part 97 radio operation. However, that would have an even bigger negative impact on the hobby by arbitrarily restricting innovation. Imagine if we had to tell technically-minded newbies in the hobby that “well, we have this rule that says you can’t actually use the biggest technology shift in the 21st century” while using ham radio. We do have some rules concerning awards and contests such as you can’t use a VoIP network to qualify for DXCC. There will probably be more of that kind of restriction occurring as technology moves forward, which is fine by me.

What’s Next?

When it comes to technological change, it’s often difficult to predict the future. Some of it is obvious: we’ll see higher bandwidths and more wireless coverage on the planet as 5G and other future technologies roll out.  Figuring out how this affects ham radio is a bit more difficult. Right now, there are still remote locations that aren’t on the network but that will change. I expect even remote DXpeditions to eventually have excellent connectivity which could lead to instant check QSLs. (That’s kind of happening already but it could become more of a realtime event.)

As systems become smarter (e.g., machine learning, artificial intelligence), distributed systems will become more automated. We can expect more automation of ham radio activity which will certainly be controversial. Did you really work that other station if the software in your home ham station made the contact while you were away at work?

To wrap up, I don’t think the internet is destroying amateur radio but it is certainly changing it. The key is to keep having fun and enjoying the hobby. If you aren’t having fun, you probably aren’t doing it right.

Pursue Radio Operating Goals

Posted on by — 1 Comment ↓

Operating goals or awards are a fun way to keep focused on accomplishing something via ham radio. Really, it’s a specific reason to get on the air and make radio contacts. I am not big on idle chit chat via the radio (“the weather here is 65 deg and raining”) so having a reason to make contacts helps me get on the air. I’ve tended to pursue awards in a serial manner…once I hit some level of accomplishment, I usually declare victory and move on to something else.

Way back in the wayback machine, the first award I pursued was Worked All States (WAS). It does take some effort but I was pretty active on the HF bands at the time, so many of the states just showed up in my log. But to really drive it home, I kept track of which states I still needed and actively looked for opportunities to work them.

Next up was Worked All Continents (WAC), which obviously requires working some DX. But then I decided that if I was going to have any DX cred at all, I needed to get DX Century Club (DXCC). This turned out to be a bit of a challenge with my modest station (100 watts and a dipole) but I found that working DX contests to be very helpful. The big hassle was collecting the QSL cards and getting them checked by the ARRL (back before the Logbook of the World was a thing). Once I checked the box on DXCC at just over 100 countries, I was satisfied and went on to other things. Serious DXers chase all available countries/entities to get Honor Roll and other bragging rights.

The VHF and higher bands have always been a passion for me, so I pursued the VHF/UHF Century Club (VUCC) awards. First, it was 6 meter VUCC, the easiest one to get. A really good run during the ARRL June VHF contest can produce the 100 grids you need for the award in one weekend. For me, it took a few more contests than that after factoring in the fallout that occurs when trying to get confirmation QSLs. The 10 GHz VUCC only requires 5 grids which turned out to be not too difficult. My VHF collaborator at the time, Doug W0AH (now K4LY) and I took turns operating from Pikes Peak while the other guy went out and activated the required 5 grids. It helps to have a big honkin’ mountain nearby to use for 10 GHz operating. About this time, I got into working the LEO satellites and worked the required 100 grids for satellite VUCC. I still don’t have very many grids confirmed on 2 meters, so that one is still calling to me.

Recently, I spent some effort going for the CQ WPX Award (worked prefixes award). This is an intriguing award structure because every new callsign prefix counts as a new one. For the basic mixed-mode award, you need to work at least 400 different callsign prefixes. I found this format to be a lot of fun because “everyone is DX” so to speak, but DX prefixes are also very valuable. This scoring approach is used for the WPX contests, which naturally brings out stations with less common callsign prefixes. A big motivator for me was when the ARRL announced Logbook of the World (LoTW) support for the CQ WPX awards. I mean, there was no way I was going to collect 400 QSL cards to submit for this award, but using LoTW made this very efficient. More on that story here: CQ WPX, LoTW and the End of QSL Cards.

Summits On The Air

Lately, I’ve been active in the Summits On The Air (SOTA) program, both activating and chasing summits. This is a natural fit for me as I’ve enjoyed mountaintop operating in various forms, mostly on VHF and UHF. (See my SOTA blog postings.) The SOTA program has a wide variety of awards, supported by a very powerful database used to record SOTA radio contacts and keep track of the scores. It is not really a competition but there is friendly rivalry between SOTA enthusiasts as they monitor each other’s posted scores.

I’ve been using VHF (and UHF) exclusively for SOTA and managed to qualify for the Shack Sloth Award using just those bands. (Shack Sloth is achieved with 1000 chaser points.) Shack Sloth is a bit of a misnomer for me as many of my SOTA chasing contacts were done while hiking, mobile or portable (not sitting at home in a shack). The Mountain Goat Award is taking a bit longer because I have to drag myself up enough summits to reach 1000 points as a summit activator.

Here’s the current scores for the Colorado (W0C) SOTA activators:
At the top of the list, we find Carey KX0R totally killing it with 2808 points. These folks have all reached the coveted Mountain Goat status: KX0R, K0MOS, K0JQZ, W0CCA, KC0YQF, W0CP, KC5CW.  I am further down the list, tied with AD0KE at 302 points. Now, remember this is not a competition 🙂 Honestly, I wish I were further along the path to Mountain Goat but I’ve decided to not fret too much, keep working at it and enjoy the journey. Walt W0CP recently gave me some excellent advice: just keep making progress.

Other Goals

You may not find the awards and goals I’ve mentioned to be very interesting, but there are many other options. In 2016, the ARRL sponsored the National Parks On The Air (NPOTA) program, which created a lot of interest and activity. I did just three activations for NPOTA but many people really got into it.

You might also set your own personal goal, not associated with any award. I know one ham that decided his goal was to make a ham radio contact every day of the entire year. This sounds simple but if you have a full-time job and other responsibilities, it takes some persistence to make this happen. Perhaps you are public service oriented; you might set a goal for the number of ARES events you support this year. I challenge you to think about what it is you are trying to do with ham radio and set a goal that is consistent with that.

Those are my thoughts, what do you think?

That’s Not Real Ham Radio

Posted on by — 11 Comments ↓

Things had been pretty quiet on the ham front lately but then I ran into a string of “That’s Not Real Ham Radio” discussions. This happens from time to time…I usually ignore it…but this time I got sucked into the topic.

It started with some HF enthusiasts I know talking about how “digital modes” are just not very satisfying. Their point is that with CW and SSB, there is an audio connection to your ear that makes you an integral part of the radio communication. The extreme-DSP modes such as JT65 insert serious signal processing that essentially removes the human connection.  This can quickly lead to the generalization that these digital modes “aren’t real ham radio.”

I think its fair to say that most hams think of the HF bands as the center of the hobby…getting on the air, bouncing signals off the ionosphere to talk to someone over the horizon. Some hams will go even further and say that CW is the only way to go. Anything less is just phone. FM and repeaters? Forget that stuff…not enough skill required. And certainly, don’t get stuck on 2 meters.

In a previous post, I argued we should not confuse religion with modulation. I do occasionally make snarky comments about the continued use of AM (AKA Ancient Modulation), but I’ve tried to tone that down in recent years.

What About DMR?

Just last week, I was playing around with a DMR hotspot on the Brandmeister network. It really struck me that people on the system were having a blast talking to each other across North America and around the world. But then that nagging little voice in the back of my head said “hey, wait a minute…this is not real DX…the RF signal might only be traveling 20 feet or so from an HT to a hotspot.”

This caused me to put out a plea for insight on twitter:

I received a lot of good replies with the answers tending to clump into these three categories:

  • I don’t know (“That’s Not Real Ham Radio”)
  • It’s fun, new technology
  • It’s a digital network that brings ham radio operators together

My interest seems to fall into the second category: this is fun, new technology. Which does make me wonder how long this new technology will remain interesting to me. Well, that is difficult to predict but I’ll invoke the principle of try not to overthink it. The idea that DMR is a digital network that brings ham radio operators together makes some sense. In the past, I have argued that amateur radio is not for talking. In other words, if you just want to talk someone, there are much more convenient ways of doing that. Still, there is something attractive about this ham-radio-only digital network.

It really is important to not overthink this kind of stuff. Ham radio is supposed to be fun, so if you are having fun, you are probably doing it right. If you are not having fun, then you might want to examine what you are doing. See my post on the Universal Purpose of Amateur Radio.

Sometimes hams can get a little spun up about those other guys that don’t appreciate our way of doing ham radio. What the heck is wrong with them anyway? I’ve always been inspired by the Noise Blankers Mission Statement:

Do radio stuff.
Have fun doing it.
Show people just how fun it is.

If your preferred form of ham radio is so superior, it ought to be easy to show other hams how cool it is. If not, then maybe you aren’t doing it right. Conversely, as long as other hams are having fun and operating legally, don’t knock what they are doing. In fact, encourage them. We need more people having fun with ham radio, even if it’s not your favorite kind of fun.

That’s my opinion. What do you think?

DX, Artificial Scarcity and The List

Posted on by — 3 Comments ↓

dxEconomists see scarcity, supply and demand as fundamental forces in a market. Items that are scarce demand a higher price while items that are easy to obtain tend to have a lower price.  A diamond is an example of something that is relatively scarce (and in demand) so it commands a high price. In contrast, wood is generally available and is much less expensive than diamonds.

Then there’s the concept of artificial scarcity. If some items can be made scarce (or even just appear scarce), the price will tend to increase. For example, if I own all of the banana trees on an isolated island, I could reduce the available supply of bananas and command a higher price from all of the banana eaters there. Or maybe I start screening bananas for quality and I put a special sticker on them to brand them as special. The special bananas can demand a higher price, because they are more scarce.

bananaWe have a case of artificial scarcity in ham radio, called the DXCC list. This list defines what is considered a separate country when chasing DX. (Actually, the correct term is entity, not country.) For example, Hawaii (KH6) and Alaska (KL7) are considered separate entities even though they are part of the United States. (See Is Alaska a Country?) For someone chasing DXCC entities, because Alaska is on The List, a radio contact with Alaska becomes more desirable. It’s kind of like putting a “premium sticker” on a banana to indicate that it is special.

In my imagination, the DXCC list resulted from a bunch of hams sitting around drinking beer and bragging about how many countries they had worked. One guy, Larry says he just worked Hawaii, bringing his total to 125 countries. His buddy Leroy says, “You can’t count Hawaii because it’s part of the US of A.”  To which Larry says, “You bet I can count Hawaii…and Texas too. It’s a whole ‘nuther country.” Clearly, we are going to need an official list to keep track of what counts as a country.  A more credible version of how the list got established is captured in this article from the October 1935 QST.

Of course, the two main factors that drive scarcity of DXCC entities is the ham radio population and ease of access. Radio contacts are easy to make with entities that have an active ham population. If an entity doesn’t have many active hams but is easy to get to, someone will probably put that location on the air once in a while.  On the other hand, some locations are unpopulated and really difficult to get to. These are not only on The List, they are on The Most Wanted List.

Kingman Reef (KH5) was just deleted from The List, instantly changing it from one of the most desired contacts in amateur radio to a big giant Why Bother. You see, there used to be 340 countries on the list but now there’s only 339. Kingman Reef will now be considered part of Palmyra/Jarvis, so it still has value for DXCC, just a lot less.

As I write this article, there is a major DXpedition (VKØEK) operating from Heard Island, an unpopulated island near Antartica. The only reason those guys are there is that Heard Island is on The List. Take a look at their web site and you’ll see how much time and energy has gone into activating this lonely island. Drop it from the list and suddenly a radio contact with this location is a lot less in demand.

So try to keep this all in perspective. There are lots of radio contacts out there to be made, some more interesting and desirable than others. It is appropriate and necessary that we have the DXCC list, to provide consistency in how we count countries, I mean entities. But really, it all traces back to Larry and Leroy arguing about who worked the most countries.

Thanks to the dedicated DXpeditioners that put these rare locations on the air.

Are Kids the Future of Ham Radio?

Posted on by — 36 Comments ↓

ham radio kidsYou’ve heard it a million times: our kids are the future. That statement gets applied to almost everything, including amateur radio. How can you argue with an obvious fact like that?

But I am starting to think it is incorrect.

We’ve had really good success on creating new hams of all ages in our Technician License Class (at the Tri-Lakes Monument Radio Association). We’ve been doing this for a while now and I think I am seeing a pattern emerge. We’ve been able to attract middle schoolers to the class and help them get their ham radio license. I’ve talked to many of them on the air. They’ve helped out with public service events. They seem to have fun playing with radios.

Then this thing called high school happens. The high school phase in the US is filled with tons of stuff to do: studying, homework, AP classes, science competitions, sports, dating, movies, driving and after school jobs. Way too much stuff. Ham radio starts to take a backseat to these normal high school activities. Then we don’t see the kids at the radio club meetings or chatting on the local repeater because they are busy doing other things. Have we lost them forever? Not sure.

High school is often followed by college which has its own set of challenges: a totally new environment, away from home, a new set of people, new studies, etc. There might be a ham radio club on campus but maybe not. If a kid is not off to college they are (hopefully) out doing something to establish themselves in this world. Eventually they emerge on the other side, get a job, get themselves established, sometimes with a spouse and maybe a kid or two. By this time they are 25 to 30 years old, depending on the individual.

I recently posted about the demographics of our students in the Tech License Class. The chart below shows the age distribution of our students from our most recent class. Hmmm, clearly most of our students are 30 or older. (Sorry, we have not collected age data with finer resolution.) This particular class is light on the under 18 crowd…sometimes we have a clump of kids in the mix.

chart1For whatever reason, it seems that most people find themselves in a situation as an adult that causes them to say “I want to get my ham radio license.” When asked why they want to get their ham license, the top response is always emergency/disaster communications, followed by backcountry communications, pursuing electronics as a hobby and learning about radio communications. I suspect that starting to be established in a community and having some disposable income also play a role.

My hypothesis is that the most effective way of growing a vibrant ham radio community is to target adults ages 25 to 40.

This age range is more equipped and ready to be ham radio operators and are still young enough that they will be around for a while. Of course, we still want to work with all age groups, including kids and retirees. We’ve all seen very young hams get the bug for ham radio early and carry it throughout their life. And we also see plenty of older folks get interested in the hobby as they approach or enter retirement. We don’t want to miss out on either of those groups.

So that’s my read on the situation. I’ve got some data to support my theory but I can’t really prove it. What do you think? What are you seeing in your ham radio community?
