Speaker Wire Delta Loop Antenna for 20M
Antennas/Delta loop
The antenna I built was inspired by a portable delta loop designed by Doug DeMaw, W1FB. Given that I constrained myself to a 50-foot roll of speak wire, I scaled my antenna for the 20M band. Using the formula, 1005 divided by the frequency in megahertz, I calculated a total length of 71 feet (21.6 meters) for the center of the 20M band.

Homebrew Z-Match Transmatch
Antennas/Tuners
For this project, I decided to try my hand at building a Z-Match tuner from scratch. This type of tuner has been around for a while. While the Z-match can take on several variations, what distinguishes it from other circuits is that it is a resonant circuit that uses a fixed inductor.
EggBeater Antenna for VHF UHF
Antennas/Satellite
This antenna was conceived mainly for high-speed digital transmission via satellite. The antenna is made of two full waves loops , mounted at right angles to each other. Then coupled together, 90 degrees out of phase over a horizontal circular reflector. With this configuration the antenna is omni directional and circularly polarized.
Proclaiming Field Day!
With 2023 Field Day fast approaching, many amateur radio operators are busy scouting their locations and getting their equipment ready for the big event.
State Sections and individual clubs are also working on publicizing Field Day and obtaining proclamations from local and state governments. It's a great way to help get clubs noticed and to draw attention to amateur radio.

Chokes and Temperature changes
Antennas/Feed Lines/Choke
The influence of temperature changes in Common Mode Chokes. To get an indication of the impedance behavior when the core temperature changes, the author tested a CMC by heating it with a hairdryer, and measuring its temperature with an infrared thermometer. When the CMC temperature rises from 30C to 90C, the frequency of maximal impedance shifts down from ca.10 MHz to ca.7.2 MHz, or by a factor 1.4.
