Ham News: Strong radio blackouts and X-Flares, SKYWARN training classes, New books from the ARRL, VHF/UHF Narrow Banding.
Questions for the evening:
What's the "smallest antenna" one can put up for 2M?
HF DX-peditions are going on now! (For a week). Where to find them.
Arduino What do you do with it?
Topic for tonightâ¦
VHF/UHF propagation from K5BPC. Explanation of "line of sight" propagation. It's a donut! Also moon bounce - use a telescope to track!, Vertical polarization and horizontal polarization for DXing on VHF.
Antennas smaller than 1/4 wavelength are not efficient.
W5SGV - NVIS build! What is it? How does it work?
Proper usage of the phrase "re-check"?
Rookie question: Vertical antenna shifted 30 degrees - does that kill the antenna signal? (oh yeah!)
