Video blog episode 012

It’s been a while, but I finally have put together another video.  It starts a new series on small transmitting loops (“magnetic loops”), the workhorse type of antenna at my station.  These antennas are a great option for working on HF when you have very limited space.  Part I of the series gives introductory information and how to do the calculations to design a loop that works for your situation.  Later videos will show how to build and use this type of antenna.

This post talks about the station upgrades I made before the contest, while the next one will be about the contest itself. Continue reading
