The folly of throwing away cruft from my desk last week caused concern for my mental health. Fortunately the bearing lives. This week I look at ball-bearings, no, antennas and how an Amateur License helps you understand the drivel that manufacturers use to describe their product and expose some of the fun and games associated with helping a fellow spectrum user. Foundations of Amateur Radio is a weekly radio podcast about the wonderful activity of ham radio and covers the 1000 different hobbies that make up this wonderful pursuit, one concept at a time. You can listen to the current and previous edition at http://podcasts.itmaze.com.au/foundations/ or on iTunes by searching for VK6FLAB.
