Data on Amateur Radio Operating Habits

Most active hams know many other radio hams and we think we have a handle on what ham radio activity is occurring. But our look into the hobby is limited by who we hang out with and the sources of information we consume. Also, we can see that the ham population is aging which is going to have a significant effect on amateur radio activity but we may not have any reliable data.

In general, the amateur radio community lacks publicly available data on amateur radio operating habits and demographics.  So I was excited to see the Operating Patterns Among Canadian Amateurs authored by my friend Frank Howell, K4FMH. This report analyzes the survey of Canadian hams done by Radio Amateurs of Canada (RAC) in 2021. Frank is a Real Researcher, so he applies generally accepted statistical techniques to aid in understanding the data. I would have preferred a study of US radio amateurs, but it seems reasonable that the operating habits of Canadian hams would be similar to US hams (and perhaps a good proxy for other developed nations). Anyway, it is the data we have and it is probably useful. I encourage you to download the report and read it for yourself, but I’ll comment on three findings from the report that strike me as significant.

Digital is really popular

The figure below is a chart that shows the popularity of different operating activities. No surprise, Casual Operating and Traditional Voice Modes score very high. But number three is Digital Modes, almost as high as Traditional Voice Modes. Depending on your operating habits, you may be thinking “well,of course, digital is very popular” but others may think “really, people like doing that?” The report also points out that digital operation is correlated with age, with younger hams using digital more than older folks.

Ham careers can start at any age

Another interesting finding is that the classic stereotype of “young person discovers radio and pursues it as a lifelong hobby” is not universal. The report shows that people enter the hobby at a variety of ages and then pursue it with varying intensity. Quoting the report:

Thus, these data illustrate that our conventional image of the amateur who gets licensed early in life and maintains that hobby activity throughout is largely a stereotype. Although it is one based upon real-world examples who fit it ideally.

I see this when teaching Technician license classes. The ages of our students typically span a wide range, including youth, but many of them are over 40 years old, entering the hobby later in life. In addition, we have quite a few students around retirement age (60 or so) looking for an activity to engage in during retirement.

The ham population is aging

You are probably thinking: duh, of course it is aging. The report puts some numbers on it, comparing it to the general population in Canada (see figure below).

Clearly, the ham population is over-represented in the age groups above 50 years. Often, the conventional thinking is “we have to get the kids involved,” which is a worthy thing to do. However, the report warns us that this won’t be enough:

This pattern has two clear implications for amateur radio in Canada. One is that the age groups of 60-80 years of age, now dominating amateur radio as the RAC Survey suggests, will simply disappear as they age-out to infirmity or becoming Silent Keys. Yet, their non-ham radio peers are scheduled to grow in number. (A recruitment focus on late-in-life hams is a clear policy for RAC to consider.) A second implication is that teens will be a relatively scarce recruitment commodity in terms of the age pyramid. There will simply not be enough of them to replace those Baby Boomers now dominating the hobby, regardless of the recruitment resources directed toward them.

This is not a call to give up on recruiting youth:

This should not be misconstrued to suggest that it would be a waste of time to expose young people to amateur radio as a recruitment method.

More to consider

This post highlights three findings that I found to be interesting. There is much more information included in this report and I encourage you to read and ponder it. I’d certainly like to see more of this kind of work published, especially for the ham population in the US, Europe and Japan. I find the demographic analysis compelling, indicating that we will see a decline in the number of radio hams in the next decade or so. We can probably reduce this decline but not stop it (my opinion, worth at least what you paid for it.). Perhaps the way to think about the challenge is to focus on having a smaller but more vibrant and active amateur radio community in the future.

These are my thoughts for today.
What do you think?

What CW recipe do you want to learn….part one?

 


 Yes, you read it correctly......within the world of CW there are recipes that one finds they are following but before you follow a recipe you have to learn the ingredients for that recipe. The CW recipes that I am aware of are POTA including the other variations, conversational CW, DXpedition hunting and contesting. Most who want to learn CW do so with a particular interest in mind. Every recipe involves ingredients and each of the above CW recipes involves certain recipe ingredients that one needs to learn and get better and better at. So in part 1 let's begin with the one I am most familiar with....contesting. This was the main reason I wanted to learn CW. 

If you are interested in contesting then what are the ingredients for CW contesting.... Letters, numbers, speed and accuracy. How serious you want to get will determine such areas as speed but letters, numbers and accuracy will always be a mainstay in the recipe. Once you have the letters and numbers down you are then good to go for call sign and number string practice. There are many call sign and number practice programs on the internet. There is LWCO, Morse Code World, Morse Code Ninja and then there are programs as well such as Morse Runner, G4FON contest and RUFZxp contest programs to name a few. Best of all there is the real deal and that is getting on the air and operating contests. Start out doing search and pouncing call signs in a contest. Avoid call sign spotting programs as these do not exercise recall, retention and eventually instant recognition. As you continue to practice you will find with some letters and numbers that instant recognition is happening.

 There is a rhythm to CW contesting and you will find like all of us you will get used to the rhythm.....how do I know this you ask? Well in a contest when a station goes off script you can get lost. For example, you get asked to QSY to 14.023 or PSE UR CALL AGN not to worry as I have read even the seasoned contesters get thrown off now and then. In contesting you will only have to instantly recognize a few phrases. Such as NR?, TU, and AGN? (sometimes with or without "?") and that is about it. 

There are some things if you choose you don't have to worry about in contesting. Because contesting programs such as N1MM+ do everything for you. Sending manual code is optional as macros within N1MM+ look after everything. You won't have to worry about recognizing common QSO words and phrases. 

So what will contesting do for you......your code accuracy will improve, your speed will improve and instant recognition will happen. Also when you dip your toes in the big boy pool and call "CQ TEST" you will have the joy of multiple stations coming back to you. The brain is an amazing thing and I can attest to the fact that when you practice (using the above-named contest programs) multiple stations come back to you in time your brain will pull out one station. You may or may not get the complete call but you will have something to go back to them with. 

In closing the recipe of CW contesting can include as many ingredients as you like. As you master one you can add another and so on. Not all like contesting and that is why in CW there are other recipes one can follow. Next time we are going to look at the CW conversational recipe. As a side note to have access to the G4FON program you need to join the Long Island CW club or LICW. I am a member and its an amazing group. Check out the link and see what they are all about.
