Are Kids the Future of Ham Radio?

Posted on 21 November 2015 by Bob K0NR — 36 Comments ↓

You’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.

For 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?

Where Are The New Technicians Coming From?

Posted on 28 October 2015 by Bob K0NR — 3 Comments ↓

We just wrapped up our Technician license class sponsored by the Tri-Lakes Monument Radio Association. Thirty people took the Technician exam with 27 passing (90%). Four people went on to pass the General exam.

We offer the class twice per year and it always fills to capacity. Invariably, we wonder “where are these new hams coming from?” and instituted a survey to try to find out. Here’s the data from the most recent class, which is typical of previous classes.

Demographics

The class was almost all male (90%) and mostly above the age of 30. From time to time, we’ve had groups of Boy Scouts come through the class which shifts the age profile a bit lower.

We ask about how they found out about the class. These responses overlap so we have them check all that apply. Most of these people find out about the class through normal “ham radio channels”, including the ARRL web site. A few people in the “other” category mentioned notices published in local weekly newspapers.

Here’s where it gets interesting. Why do they want to get their amateur radio license? Disaster and emergency communications continues to be the most common answer at almost 90%. This is followed by the closely-related Backcountry/Remote Communications (about 80%). About 60% of the respondents selected radio and electronics as a hobby. More than half said they want to learn about radio communications.

Not to be overlooked is the influence of family and friends at 45%. We often see family members of current radio hams that were ~~badgered~~ encouraged to get their radio license. We do see more than 20% that see a ham radio benefit to their involvement with fire, search and rescue, law enforcement and similar agencies.

Summary

Emergency and disaster preparedness rank high in the reasons why these people are interested in amateur radio. This may be fueled locally due to the recent devastating wildfires in Colorado. Many people experienced first hand what happens to the mobile phone and landline systems when disaster strikes. When All Else Fails. The other major motivation is the traditional hobby aspect of amateur radio. People like to learn about technology and have fun experimenting with it. Lately, this has taken the form of the Maker Movement.

You’ve Got Questions, We’ve Got Answers

Posted on 26 September 2015 by Bob K0NR — No Comments ↓

K3NG has performed an important public service by tabulating the answers to the top ten amateur radio questions swirling about the interwebz. This will save thousands of hours for hams searching for this critical information.

Unfortunately, K3NG did not include the questions, so you will have to use your imagination. But it’s not difficult.

The Ten Essentials for Hiking (and SOTA Activations)

Posted on 16 August 2015 by Bob K0NR — 3 Comments ↓

Most backcountry hikers are familiar with the Ten Essentials that you should take with you whenever you head into the wilderness. Over the past few years, I noticed that I was getting a bit sloppy with regard to what is actually in my pack when I head out on the trail. This hit home one day when my GPS battery went dead. I fumbled around to find my compass which was supposed to be in my pack. Well, it was in my pack, the other one that I left at home.

This caused me to review the list of ten essentials to make sure I had the right stuff in my kit. A search on the internet revealed that the classic list of ten has been modified and augmented by various people to make it better. (Innovation runs rampant on the interwebz, you know.) One of the better resources I found was this page on the REI web site, which explains how the Classic Ten Essentials have been updated to the Ten Essential Systems:

Navigation (map and compass)
Sun protection (sunglasses and sunscreen)
Insulation (extra clothing)
Illumination (headlamp/flashlight)
First-aid supplies
Fire (waterproof matches/lighter/candles)
Repair kit and tools
Nutrition (extra food)
Hydration (extra water)
Emergency shelter

Read through the REI web page to get the fine points of this system approach. I won’t repeat that information here. They also include a Beyond the Top Ten list which calls out the need for:

Communication device: Two-way radios, a cell phone or a satellite telephone can add a measure of safety in many situations.

Of course, what they really mean is an amateur radio transceiver and antenna but they probably can’t say that in print due to licensing issues. (Not everyone in the backcountry has an FCC ham license. I know, they all should have an amateur license but many don’t…very hard to understand 🙂 )

So how are you doing with your Ten Essentials list? Are you consistent in taking along the right stuff in your pack? Any tips to share with hiking hams?

Three Common Mistakes When Using Metric Units

Posted on 16 May 2015 by Bob K0NR — 6 Comments ↓

A while back, I had someone point out a few errors I made concerning the use of metric units. This caused me to review the SI system to make sure I had it correct. (I am sure I’ll continue to screw up a few things but, hey, life is a journey.)

The International System of Units, universally abbreviated SI (from the French Le Système International d’Unités), is the modern metric system of measurement. For a thorough treatment of the topic, take a look at the National Institute of Standards and Technology (NIST) publication: Guide for the Use of the International System of Units (SI). A shorter and easier-to-read document was written by Charles Poynton: Writing SI units and symbols.

But more to the point, here are three common mistakes I often see occurring in ham radio literature:

Using mHz instead of MHz to indicate megahertz (one million hertz). Upper case M indicates mega, while lower case m indicates milli (one thousandth). In ham radio usage, we rarely speak of frequencies in mHz. Note that I wrote mega with a lower case m even though the abbreviation has a upper case M. The unit of hertz is with a lower case h but when abbreviated as Hz, it should be upper case.
Using KHz or khz instead of kHz to indicate kilohertz (one thousand hertz). Lower case k should be used for kilo but upper case H is used for hertz. It is common to see upper case K used to indicate 1024 in digital systems.
Using M instead of m to indicate the unit of meter. The proper way to refer to the wavelength of the 144 MHz ham band is 2 m, not 2M. Similarly, the abbreviation for kilometers is km, not kM or KM. The abbreviation for centimeter is cm.

Units that are based on a person’s name use an upper case letter in the abbreviation. For example, ampere, volt, watt and hertz are abbreviated as A, V, W and Hz respectively. When the unit is spelled out, it is left lower case (go figure).

While the world does keep on turning when we make these mistakes, accuracy and understanding is improved by proper usage. Did I miss any other common SI errors?

Explaining Standing Waves

Posted on 25 April 2015 by Bob K0NR — 1 Comment ↓

When we teach the Technician License Class, we provide a simple explanation of Standing Wave Ratio (SWR) that emphasizes the concept of impedance matching. An SWR of 1:1 is a perfect match; anything higher is less than perfect.

SWR is an important amateur radio concept, one that is not that easy to explain so I am always on the lookout for training materials. HamRadioNow just republished this video of an excellent standing wave demonstration by Bill Hays, AE4QL. Bill actually goes well beyond just standing waves and shows some antenna and transmission line theory as well.

If you just want to learn about standing waves and basic antenna radiation, view the first 35 minutes. After that, it starts to get a little deep.

Grab a cup of your favorite beverage, settle in and get ready to learn from this video.

ARRL Field Day: Season To Taste

Posted on 18 March 2015 by Bob K0NR — No Comments ↓

I’ve written before about the flexibility of Field Day and the need to season to taste to make it your own. I have always thought that one of the great things about Field Day is that it can be tuned to whatever interests you or your club. It can be a serious radio contest (well, almost); it can be an emcomm drill. It can be a radio campout; it can be a foodfest, it can be a beer-drinking party. Insert your idea here.

This year, our local club, the Tri-Lakes Monument Radio Association is going to try a new approach that we call Tech Field Day. We previously have held a one-day educational event that we call Tech Day, that featured a series of presentations and hands-on demonstrations. The main theme of Tech Day was to help the Technician level hams gain more knowledge and help them move on up to General class operating.

We are taking the basic idea of Tech Day and combining with a shortened one-day version of Field Day. So on Saturday June 27th, we’ll offer a series of educational presentations along with some classic Field Day radio operating. The operating emphasis will be on giving newer hams a chance to get on the air, probably on both HF and VHF. (Our plans are still coming together.) We will also promote the theme of emergency communications, operating off a emergency power source, etc.

There are a number of things that we are intentionally leaving out. We won’t operate the entire 24 hour period…in fact, we’ll probably just be on the air Saturday afternoon. We won’t worry about making a lot of contacts or running up the score. Our stations will be relatively simple (no towers, no amplifiers).

So that’s our idea of a fun Field Day. What are you planning to do?

Three Steps to Getting Your Ham Radio License

Posted on 12 October 2014 by Bob K0NR — 2 Comments ↓

These are the three basic steps to getting your USA amateur (ham) radio license: 1) Learn the Material 2) Take Practice Exams and 3) Pass the Real Exam.

This article is very short and to the point, for a more detailed discussion see Stu (WØSTU)’s article over at HamRadioSchool.com.

1. Learn The Material

The entry level ham radio license is the Technician License, so you’ll need to get a book that covers the theory, regulations and operating procedures required by the Federal Communications Commission (FCC). My recommendation is the Technician License Course over at HamRadioSchool.com, which offers an integrated learning system (web, book and smartphone app).

While you can learn the material on your own, many people find classroom instruction to be very helpful. Check the ARRL web site for courses in your area or just do an internet search for “ham radio license class” and your location.

2. Take Practice Exams

The question pool for the Technician Level Exam is made public, so you have access to every possible question that will be on the exam. Better yet, various organizations have created online practice exams so you can test yourself in advance. After you study the material, take these practice exams to test your knowledge. Go back and study any topics you are having trouble with on the exam. A passing grade is 74%, so you’ll want to be consistently above that before trying the real exam.

These are a few of the available online practice exams: qrz.com, eham.net and aa9pw.

3. Pass the Real Exam

The FCC exams are administered by radio hams known as Volunteer Examiners (VEs), so the exam session is sometimes called a VE session. In most areas, there are exam sessions given on a regular basis. Check the ARRL web site to find a license exam session in your area. If you are taking a class, there may be an exam session included in the schedule.

Be sure to follow the instructions of the local VE team, since policies and procedures do vary. If you’ve studied the material and checked your knowledge by taking the practice exams, you should have no problem passing the Technician level exam.

4. One More Thing

Actually, there is one more step to this process. Getting the required FCC license is just the start, a learners permit for amateur radio. You’ll need to get on the air and gain some practical experience. It is extremely helpful to have some assistance during this process, so I recommend that you connect up with a local ham radio club. If you can’t find a club then perhaps make contact with a local ham or two.

Of course, it would be even better if you can do Step 4 ahead of Step 1 and get some help along the way. There are many radio hams out there that are willing to assist. However, it may be a challenge to find one. You can always drop me an email and I will do my best to help out.

What? A Record Level of US Ham Licenses?

Posted on 12 January 2014 by Bob K0NR — 7 Comments ↓

The ARRL just reported that the number of FCC amateur radio licenses hit an all time high of 717,201 at the end of 2013. Since we all know that the interwebz has made ham radio communication obsolete :-), this is a difficult statistic to comprehend. Joe Speroni AH0A keeps a useful collection of ham licensing statistics including the ability to generate plots of the data. I used Joe’s site to generate this plot of total US amateur licenses versus time. Note that the vertical axis does not start at zero, so the plot tends to exaggerate the amount of change.

From this plot, we see that the number of licenses was in decline from about 2003 to 2007. The no code Technician license was introduced in 1991 which is earlier than the data on this chart. The FCC completely dropped the Morse Code requirement from all license classes in 2007, as indicated on the chart. (See Wikipedia for the exact dates.) The decline in licenses was reversed at that time and has been growing ever since. There is an interesting inflection point in 2010 that coincides with the release of a new Technician License question pool. The line is noticeably less steep after this point, which seems to imply that something happened to slow down the rate of new licenses.

Over the last ten years, Technician licenses have grown slightly as a percent of the total, going from 47% to 49%. So about half of US licenses are Technician. The grandfathered Novice and Advanced class licenses are in a slow decline and currently represent 2% and 8% (respectively) of the total licenses. The percent of General licenses has grown slightly over the past ten years, from 21% to 23%. Extra class licenses showed the most growth over the decade, going from 15% to 19% of total licenses.

While it’s encouraging to see continued growth in the number of ham radio licenses, these statistics immediately raise a number of questions:

How many of these licensees are Silent Keys and their FCC license is just clocking time until it hits the 10 year expiration date?
Given the aging ham population, when will we hit a demographic brick wall and see the number of licenses decline?
How many of these licensees are actively involved in ham radio? I have a number of friends that keep their FCC license current but are never on the air.

Clearly, the 10 year license term will tend to mask any decline for a while but it seems that sooner or later the numbers will flatten off and probably start to decline. I don’t know of anyone that has collected and analyzed the age distribution of hams, so I am basing this on what I see at radio club meetings and major ham radio events.

How many of these licensees are active? Really difficult to say. It seems that in the 21st century, people have many activities to choose from and their interest in any one of them may fade in and out. Not everyone is a Full Up 24/7 Ham Radio Enthusiast.

In the mean time, I am going to keep teaching Tech license classes and helping people get started in a hobby that I find to be a lot of fun. Remember the The Universal Purpose of Amateur Radio: To Have Fun Messing Around with Radios.

General License Book From HamRadioSchool.com

Posted on 7 May 2013 by Bob K0NR — 1 Comment ↓

HRS General Book HamRadioSchool.com is off to a great start with a learning system that includes a web site, iPhone app and a great Technician License Course book. The Technician book, written by my fellow instructor Stu Turner W0STU, has turned out to be very popular. Stu did a great job of balancing “teaching the right material” with “focusing on the exam questions.” We’ve used the book in our two-day Tech license class with great success.

Many people have been asking Stu when he’s going to write a book for the FCC General Class License. So, by popular demand, here it is: HamRadioSchool.com General License Course. Using the same creative style that worked well with the Technician book, Stu has delivered an easy-t0-grok book for getting your General Class License.

I was happy to provide technical assistance to Stu for this book and earned the esteemed title of Technical Editor. It even says so on the front cover! (It says Technical Editor because I can’t be held responsible for proper grammar or spelling.)

Just like the Tech book, the General book has a companion iPhone app available on iTunes.

New GNT Frequency

Posted on 23 November 2012 by Bob K0NR

You may recall the story about the origination of the Golf November Tango frequency of 146.55 MHz. Unfortunately, we have discovered an oversight in the selection of this important frequency.

On the 2 Meter band in the US and Canada, we have two different channel spacings in use. Some regions use a 15-KHz channel spacing while other regions use 20-kHz channels. All regions do use 146.52 MHz as the FM calling frequency, but the other channels are spaced based on local practice. The 20-kHz spaced band plan has simplex frequencies that include 146.52, 146.54, 146.56 and 146.58 MHz. With a 15 kHz spacing, the resulting simplex frequencies include 146.52, 146.535, 146.550, 146.565 and 146.580 MHz. Clearly, the existing frequency of 146.55 MHz was only compatible with the 15-kHz band plan.

An investigation is underway to determine who actually chose this frequency, so the responsible party can be held responsible. Unfortunately, no one seems to remember how the frequency was actually chosen, so the investigation continues. In the mean time, The Committee to Preserve Golf November Tango met and decided to launch a fast-track project to establish a new GNT frequency. If at all possible, this frequency must be compatible with both types of band plans, so that a North American GNT frequency can be restored to its former glory, while fully conforming to local VHF band plans.

After an intensive 18 month investigation, the team was unable to find such a frequency. Even though they met weekly, usually while partaking of copious quantities of Gin and Tonic, they were unable to find a solution. It looked like the entire enterprise might be in jeopardy. But late one night, one of the committee members blurted out “hey, why don’t we just use 146.52 MHz since I already have it programmed into my radio?” By some quirk of fate, the other committee members thought he said “146.58 MHz”, which, in fact, does fit both band plans. The GNT frequency was quickly designated as 146.58 MHz and the meeting was adjourned.

So remember, when you are on the beach and in the need of liquid refreshment, make a distress call on the GNT frequency of 146.58 MHz.

Easy Online Circuit Analysis

Posted on 17 November 2012 by Bob K0NR

I was writing an electronics article today and started to do some circuit analysis by hand. It was a pretty simple circuit so I knew I could crank out the circuit analysis on paper but I started to think maybe there was a better way. I poked around the web and came across CircuitLab.com, a free, online circuit simulator.

Circuit Lab — A sample circuit from the CircuitLab web site.

As I gave it a try, I was amazed at how easy it was to use. I just started doing some simple drag-and-drop from my browser and the circuit quickly took shape. A few minutes later, I had my first analysis running and I started playing “what if” games with the circuit parameters.

OK, I’ll admit that the circuit I created was pretty simple but still, I am impressed. Oh, and did I mention that its free? If you have need for circuit diagrams and simulation, check out CircuitLab.com.
