“Welcome to the ARRL’s portal for Amateur Radio technology!
This page provides links to some of the technical facets of Amateur or “Ham” Radio. Hams use a lot of wireless technology that is of interest well beyond the amateur bands – antennas, feed lines, towers, receivers, transmitters, digital protocols and networks. Along with the topics of radio, you’ll also find the hams-eye view of microprocessors, power supplies, audio, instrumentation, and electronics of all stripes. Hams are into the science of solar and space phenomena, geophysics, and satellites, among other things. We hope you’ll find something interesting and useful to you in the world of Amateur Radio.” – Read Full Article:
