Amateur Radio’s Lost Tribe: The ‘Blue-Collar Scholars’ Who Started It All
By Frank M. Howell PhD K4FMH

We all know the history of US amateur radio: Hiram Percy Maxim founded the American Radio Relay League, and the rest is history, right? Not quite, says Frank Howell, who takes a closer look at the origins of what he calls amateur radio’s ‘lost tribe of blue-collar scholars,’ the thousands of unlicensed wireless experimenters who learned radio science through the pages of Hugo Gernsback’s prolific wireless publications years before there was an ARRL or QST magazine.

AM Band DXing Today
By David Yocis

With over one hundred years of listening to the AM band, you might think there’s nothing new to learn, but David shows that Twenty-first Century technology has brought new life to the oldest radio hobby.

By Jock Elliot KB2GOM

Taking small, inexpensive portable radios outdoors and turning them into DX machines is what ultralight medium wave DXing is all about.

Georg reports that’s no longer the case as he dives deep into the receivers, antennas, and software you’ll need to explore this radio territory.

From Top 40 records to network TV shows to feature films, millions of everyday Americans were ‘ratchet-jawing’ on their CB sets. But never count CB as dead—Cory reports that it’s still alive and now with FM modulation!
