Ham Radio Help Topics

08/05/2012

Out of the immense number of topics that are useful for helping new Ham Radio folks pursue, on the technical side of ham radio, there are a few areas of discussion that are particularly useful and important at this early stage of effort. Perhaps the easiest way to go about this, in this page of helps, is to start by adding those topics that cause a lot of struggle for most of us at the onset. These short presentations cannot possibly be as a substitute for the wealth of good material available, but hopefully they can provide some additional insight into some "simpler ways" of learning these things.


 "Db's the Easy Way", without calculators or complicated formulas.

 Resistor Color Code in 18 minutes!

So just what is meant by the "Characteristic Impedance" of a length of coax?

What's so special about the so-called "Quarter-Wave Shorted Stub"?

Power Supply Basics, Understanding Various  Power Supply Systems and Regulation.

You might find these outlines (in progress) somewhat informative

Morse Code:

W1AW CW Practice -- On-The-Air

Morse Code Software - See what AC6V has to offer, and really good links:

Note especially the Morse Code Training Programs

I especially recommend CW Player (by F6DQM) and NuMorse, and they will run the the following Data Files very nicely:

 Morse Code Helps:

"ReadMe" (please)

Morse Code Data Files  Here's what I have used for many years for helping folks achieve their morse code proficiency. I originally had it on audio tape, but it works very well with these Morse Code programs as a Data File. It helps by comparisons with those areas that sound so much alike, and how to deal with those dificulties. See Group Selections for a more detailed view of these test files.
Morse Code Data HTML File (given here as an html, which can be converted to a data file)
For an explantion of the philosophy of these groups.
