Explaining Standing Waves

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.

The Completely Updated Incomplete List of Ham Radio iPhone Apps

iphonesIt is about time I updated one of my more popular posts about my favorite ham radio apps on the iPhone and IPad. As usual, I will focus on free or low cost (less than $5) apps that I am actively using. Some apps have just disappeared from iTunes and new ones have emerged. While this list is completely updated, it is still incomplete, because there are so many apps to choose from.

 

From the Simple Utility Category:

Ham I Am (Author: Storke Brothers, Cost: Free) A handy app that covers some basic amateur radio reference material (Phonetic alphabet, Q Signals, Ham Jargon, Morse Code, RST System, etc.) Although I find the name to be silly, I like the app!
Maidenhead Converter (Author: Donald Hays, Cost: Free) Handy app that displays your grid locator, uses maps and does lat/lon to grid locator conversions.
HamClock (Author: Ben Sinclair, Cost: $0.99) A simple app that displays UTC time, local time and grid locator. This one reads out to the second.

 

There are quite a few good apps for looking up amateur radio callsigns:

CallBook (Author: Dog Park Software, Cost: $1.99) Simple ham radio callbook lookup with map display.

Call Sign Lookup (Author: Technivations, Cost: $0.99) Another simple ham radio callsign lookup with map display.

 

There are a few repeater directory apps out there and my favorite is:

RepeaterBook (Author: ZBM2 Software, Cost: Free) This app is tied to the RepeaterBook.com web site, works well and is usually up to date.

 

For a mobile logbook (and other tools):

HamLog (Author: Pignology, Cost: $0.99) This app is much more than a logbook because it has a bunch of handy tools including UTC Clock, Callsign Lookup, Prefix list, Band Plans, Grid Calculator, Solar Data, SOTA Watch, Q Signals and much more.

 

To track propagation reports, both HF and VHF:

WaveGuide (Author: Rockwell Schrock, Cost: $2.99) This is an excellent tool for determining HF and VHF propagation conditions at the touch of a finger.

 

If you are an EchoLink user, then you’ll want this app:

EchoLink (Author: Synergenics, Cost: Free) The EchoLink app for the iPhone.

 

There are quite a few APRS apps out there. I tend to use this one because my needs are pretty simple….just track me, baby!

Ham Tracker (Author: Kram, Cost: $2.99) APRS app, works well, uses external maps such as Google and aprs.fi. “Share” feature allows you to send an SMS or email with your location information.

 

Satellite tracking is another useful app for a smartphone:

Space Station Lite (Author: Craig Vosburgh, Cost: Free) A free satellite tracking app for just the International Space Station. It has annoying ads but its free.

ProSat Satellite Tracker (Author: Craig Vosburgh, Cost: $9.99) This app is by the same author as ISS Lite, but is the full-featured “pro” version. Although it is a pricey compared to other apps, I recommend it.

 

For Summits On The Air (SOTA) activity, there are a few apps:

Pocket SOTA (Author: Pignology, Cost: $0.99) A good app for finding SOTA summits, checking spots and accessing other information.

SOTA Goat (Author: Rockwell Schrock, Cost: $4.99) This is my favorite app for SOTA activity (finding summits, checking/posting spots and alerts, etc.)

 

For ham radio license training, I like the HamRadioSchool.com apps. (OK, I am biased here as I contribute to that web site.)

HamRadioSchool Technician (Author: Peak Programming, Cost: $2.99) There are a lot of Technician practice exams out there but this is the best one, especially if you use the HamRadioSchool.com license book.

HamRadioSchool General (Author: Peak Programming, Cost: $2.99) This is the General class practice exam, especially good for use with the HamRadioSchool.com book.

 

Morse Code is always a fun area for software apps:

Morse-It (Author: Francis Bonnin, Cost: $0.99) This app decodes and sends Morse audio. There are fancier apps out there but this one does a lot for $1.

 

Well, that’s my list. Any other suggestions?

Three Steps to Getting Your Ham Radio License

300px-International_amateur_radio_symbol.svgThese 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.

When All Else Fails or SHTF?

when-all-else-fails-logoA while back, Dan KB6NU noted the increasing number of preppers getting involved in ham radioPreppers are people who are actively preparing for emergencies, natural disasters and disruption of social order. In our Technician license course, we’ve noticed an increase in the number of people identifying themselves as preppers.

Of course, amateur (ham) radio has a long history of emergency service and disaster preparedness. FCC Rules Part 97 says this is one of the purposes of the Amateur Radio Service: Recognition and enhancement of the value of the amateur service to the public as a voluntary noncommercial communication service, particularly with respect to providing emergency communications.

Historically, most radio amateurs approach the hobby from a technical or radio operating point of view, then find ways to apply it to emergency preparedness. The prepper tends to work the equation the other way…starting with the desire to have emergency communication capability and then working to get an amateur radio license.

Many prepper sites just give a quick overview of ham radio, positioning it with GMRS, FRS and CB radio. See Prepper Communications. Articles like this one give a more complete introduction to ham radio: The Skinny On Ham: Getting Licensed.  This one, too: Every Prepper Should Be A Ham.

You may run into some creative acronyms on these prepper sites:

SHTF = “Stuff” Hits The Fan
EOTW = End Of The World
TEOTWAWKI = The End Of The World As We Know It
YOYO – You’re On Your Own

There are web sites devoted to prepping with radio communications:

Prepared Ham
RadioSurvivalist.com
RadioMaster Reports

Many of these sites have useful information that may stretch your thinking on “being prepared.” Of course, some of these prepper sites (not the ones listed above) are a bit over the top and may have resulted from people going off their meds. Draw your own conclusions.

I’ve noticed a pattern of people creating prepper frequency lists, such as the one shown below. (Note that some of the ham frequencies listed do not conform to generally accepted band plans.) I can see the usefulness of having some assigned frequencies but its not clear to me how they’ll actually get used. I think the challenge for new prepper hams is to think through who they are going to communicate with and for what purpose. It’s also important to get familiar with the equipment and gain experience on the air, so when the EOTW happens you aren’t sitting there reading the radio manual.

shtf_frequency_list_2013e_500

Whether you think of emergency communications as “When All Else Fails” or when SHTF, amateur radio is a resilient communication tool.

Added 7 Dec 2013: I came across this video that does a good job of introducing ham radio to the prepper crowd:  So you want a ham radio for emergency communications!

Introducing Ham Radio School

For several years now, I’ve been teaching a Technician License course with a team of instructors from our local radio club. We use a very successful 2-day format (90% success rate on the FCC exam), holding the class on 2 consecutive Saturdays at the local fire station. Our next session starts on Sept 29th.

For this compressed two-day class, we’ve been using the Gordon West Technician Class book and (optionally) encouraged the class to read the ARRL Ham Radio License Manual. The Gordon West book is very focused on the exam questions, with some explanation around each one. The ARRL book is more thorough and deeper technically, so it is a good reference to round out the student’s understanding. Basically, the Gordon West book is good for “teaching the exam questions” and the ARRL book is good for providing a more comprehensive understanding.

My fellow instructor, Stu Turner WØSTU, got the idea into his head that it would be good to create a license manual that gave a solid treatment of the material while still highlighting the specific questions on the exam. The next thing you know, he is off creating  a new book, Ham Radio School.com Technician License Course. Stu did an excellent job writing this book, keeping it focused on the relevant topics but going beyond just teaching the exam questions. He also has a good knack for keeping it interesting.

The story didn’t end there. One thing led to another and the book concept blossomed into a integrated learning system that includes a web site, iPhone/iPad app and (of course) the book.  The web site offers some written content and interesting videos that help people learn about amateur radio. I will be contributing some material to the web site from time to time.

The Ham Radio School iPhone app is really sweet…check it out on iTunes. All the questions from the current Technician question pool are included in both review-style quizzes and in properly weighted, full 35-question practice exams, just like the one you’ll take at your VE session.

The most important thing is that the book, the web site and the iPhone app are coordinated and work together as a system. We all have different learning styles, so the system approach allows the student to focus on what suits them best.
