The United Methodist Bishop responsible for the local churches – like other area church leaders – has closed all local UM churches until March 30 to minimize the passing of the Corvid-19 virus. Therefore RARC school classes, FCC exams, and other activities will not be held.
With proper “social distancing” the RARC met on 13 March. Because many could not be there, the presentation was recorded. Find it at:
The March Newsletter is now available. Here
Fifteen folk signed up to become new hams by taking the Technician class taught by George Starke. We did not have enough students for any of the other classes or seminars. That usually doesn’t happen in the spring. Maybe it was the not-really-winter season we had.
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 DeMajo Mag Loop presentation
John‘s presentation is available by clicking this link: loop-antenna-project
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.

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.

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.
