Designing and Constructing Magnetic Loop Antennas
Two presentations, one by John DeMajo, K5HTZ, and a second by Ken Zutavern, K4ZUT, at the 10 January 2020 RARC club meeting are outlined here.

John’s spreadsheet calculator is at mag_loop_calculator.
Ken showed another design that used a hand-wound toroid transformer instead of a small loop to feed the large loop.
K4ZUT toroid transformer and motor-driven capacitor tuning
Ken’s loop also used a motor to turn the tuning capacitor. This allows him to locate the loop away from his operating position.

RARClub.net at new hosting site
If you have problems with this site, sent a note to richmondarclub@gmail.com.
After years of Chris Walker, N4CBW, generously hosting our website rarclub.net on his site, we’ve moved it to another server. It’s taken almost a month longer than than expected but the webmaster (W4BRU) is pretty rusty not having done this since 2009.

A table of radios the makers made, a CW station, an SDR receiver with loop antenna and a spectrum display, and a SSB station. Time for ham radio fun.

Ham Radio Launched on Balloon
Four cars of hams chased a balloon carrying APRS and launched from Franklin Military Academy, a Richmond city school. KN4CZZ, chemistry teacher at the school led this, his second launch from the school. This time he used APRS and got lots of hams to chase with him.
All but two of the chase team holding the prey on a country road in New Kent County near Providence Forge
Track from APRS.FI
It didn’t go far but it went high, 84,000 feet.
Checking the lift just before launch.
