Foundations Of Amateur Radio

Foundations of Amateur Radio The single most discussed topic in amateur radio is that of antenna design, that and medical procedures on 80m, but I kid. Previously I've discussed the notion that all frequencies are on-air all the time and that your traditional radio uses much of its electronic circuitry to filter out all the things you don't want to hear. Parallel to that is the concept that you tune your antenna to be resonant on a particular band or frequency.
