Episode 80, the Passion and Politics of Amateur Radio Passion has been explained to me once as a "big elephant". You sit on its back and it takes you where you want to go. Gentle nudging makes the elephant change direction, but if it gets excitable or startled, it'll go where ever it wants and all you can do is be a passenger and hold on tight. If you mix passion and Amateur Radio, there are times when that will result in heated discussion about the merits or pitfalls of a particular radio, an antenna or some other aspect of the hobby. 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.
