Winding Toroids: Pain or Pleasure?

Lots of kits these days use toroidal inductors. These are components that you have to make yourself. The kit vendor supplies a toroid core and some magnet wire, and tells you how many turns to wind.
For some people this is a real pain. Not only do you have to get the number of turns correct, [...]

Your First Meter

One good thing about the Internet is that you can find lots of information and advice on just about anything. The bad thing about the Internet is that you can find lots of information and advice on just about anything. The problem, of course, is that much of the advice you’ll get is contradictory, and [...]

NIST Antenna Calibrations Extended to 60-110 GHz

NIST engineer Katherine MacReynolds prepares a new NIST “tabletop” range for characterizing high-performance antennas, such as horn antennas (small gold pyramids) operating at 94 Gigahertz. The surrounding blue foam cones absorb electromagnetic fields to reduce scattering from nearby objects, thereby improving measurement accuracy.Credit: © 2006 Geoffrey Wheeler.

Didn’t Get to Dayton? Watch the Videos!

This year, I didn’t go to Dayton. I figured that I already had too much junk in the shack and too many projects to work on, and if I did go, I’d come back with even more junk and more projects to put in the queue.
Fortunately, through the magic of the Web, this doesn’t mean [...]

No-Nonsense, General Class Study Guide

Well, it took me a little longer than I anticipated, but the beta release of my The No-Nonsense, General Class License Study Guide is now available. The new General Class test is a bit harder, I think, than the old test.
Anyway, I’d be happy to have any and all review this. Comments and suggestions are [...]

A Pleasant Evening in the Shack

Last night, was a really enjoyable one down in the shack.
When I first turned on the rig, it was tuned to 40m. I didn’t hear much, so I tuned up to 30m. 30m was really hopping. Almost immediately, I heard UT5XS calling CQ, and I worked him. After that short contact, I called CQ [...]
