Subelement Focus Added to Amateur Radio Practice Exams

Go take a practice test now using the links below!

The next time you practice a ham radio licensing exam here, you'll notice that the interface has changed a little bit to add a few new features.

Focused Practice on Subelements
Taking practice exams that simulate the randomly selected exams used for license tests is one of the best ways to study. But, sometimes, there's just one section of the test that is giving you the most trouble. Now, when you click the 'Practice Subelements' button, a control panel will appear that allows you to restrict your study to a single test subelement.


When you click on the button for a subelement you will only be presented questions from that subelement. The button for the subelement you've selected will be highlighted with a different colored background.

After you've studied the subelements you wanted to focus on, just click 'Practice Exam' to take a new practice test.

It also helps to know which subelements you need to study. The charting facility has been updated to easily show your relative performance on all the test's subelements. By clicking on the 'Show Scores' button, you will be presented with a graph of your practice test scores over time, as well as your relative performance on each subelement.

The example shown here indicates that I could really use a little more work on subelement G6. After you've analyzed your scores, simply click the 'Hide Scores' button to make the charts disappear. Historical test scores are only stored for users that are logged in. If you aren't logged in, your subelement chart can still be viewed after you have completed a practice exam. Creating a login account is simple. Just enter any name and password into the login box on the right hand side of the test page and click the 'Create' button.

No other information is required. The login name is used to find your test scores and chart them for you.

Have fun practicing!

More Cowbell! Record Production using Google Forms and Charts

First, the what : This article shows how to embed a new Google Form into any web page. To demonstrate ths, a chart and form that allow blog readers to control the recording levels of each instrument in Blue Oyster Cult's "(Don't Fear) The Reaper" is used. HTML code from the Google version of the form included on this page is shown and the parts that need to be modified are highlighted. Next, the why : Google recently released an e-mail form feature that allows users of Google Documents to create an e-mail a form that automatically places each user's input into an associated spreadsheet. As it turns out, with a little bit of work, the forms that are created by Google Docs can be embedded into any web page. Now, The Goods: Click on the instrument you want turned up, click the submit button and then refresh the page. Through the magic of Google Forms as soon as you click on submit and refresh this web page, the data chart will update immediately. Turn up the:

Cool Math Tricks: Deriving the Divergence, (Del or Nabla) into New (Cylindrical) Coordinate Systems

Now available as a Kindle ebook for 99 cents ! Get a spiffy ebook, and fund more physics The following is a pretty lengthy procedure, but converting the divergence, (nabla, del) operator between coordinate systems comes up pretty often. While there are tables for converting between common coordinate systems , there seem to be fewer explanations of the procedure for deriving the conversion, so here goes! What do we actually want? To convert the Cartesian nabla to the nabla for another coordinate system, say… cylindrical coordinates. What we’ll need: 1. The Cartesian Nabla: 2. A set of equations relating the Cartesian coordinates to cylindrical coordinates: 3. A set of equations relating the Cartesian basis vectors to the basis vectors of the new coordinate system: How to do it: Use the chain rule for differentiation to convert the derivatives with respect to the Cartesian variables to derivatives with respect to the cylindrical variables. The chain

The Valentine's Day Magnetic Monopole

There's an assymetry to the form of the two Maxwell's equations shown in picture 1.  While the divergence of the electric field is proportional to the electric charge density at a given point, the divergence of the magnetic field is equal to zero.  This is typically explained in the following way.  While we know that electrons, the fundamental electric charge carriers exist, evidence seems to indicate that magnetic monopoles, the particles that would carry magnetic 'charge', either don't exist, or, the energies required to create them are so high that they are exceedingly rare.  That doesn't stop us from looking for them though! Keeping with the theme of Fairbank[1] and his academic progeny over the semester break, today's post is about the discovery of a magnetic monopole candidate event by one of the Fairbank's graduate students, Blas Cabrera[2].  Cabrera was utilizing a loop type of magnetic monopole detector.  Its operation is in concept very sim
