About the Author

Terry L. Barlet, N0TLB
Amateur Extra Class Operator · Creator of Ham Radio Base

I'm a licensed Amateur Extra Class operator and the creator of Ham Radio Base — this site, its 180+ antenna build guides, calculators, and my books all come from the same place: a genuine, lifelong interest in how electronics actually work, not just a marketing angle.

I got interested in electronics as a teenager, around 15 years old, and studied electronics engineering right out of high school. My career, though, went a different direction — I spent decades in heavy construction equipment maintenance, eventually working my way up to regional manager in that field. But electronics never stopped being the thing I actually did for fun. Over those years I built my own systems, repaired my own electronics, and even ended up repairing vehicle computers on heavy equipment — the engineering background found its way into the job whether the job called for it or not.

After retiring, I went back to school to formally brush up on modern electronics — digital systems, the things that had changed since I first learned the fundamentals decades earlier. I'd gotten interested in ham radio about 20 years ago, but didn't actually get licensed until 5 years ago. I currently hold an Amateur Extra Class license.

Everything I've written started as free content on this site first. Each series is a print companion to material you can read here right now at no cost:

Radio Electronics for Amateur Radio Operators (5 volumes) — the print companion to the full electronics course on this site, taught specifically for what a radio operator actually needs rather than adapted from a generic textbook.
The Complete Ham Radio Antenna Build Guide (5 volumes) — the print companion to the 180+ antenna build guides here, practical and built for actually building the thing, not just reading about it.
License Study Guides (3 volumes — Technician, General, Amateur Extra) — the print companion to the license study guides on this site, built from the experience of actually sitting for and passing that exam myself.

All 13 volumes are available in paperback, hardcover, and Kindle editions. See all books and buy direct.

Everything on this site comes out of that same 50 years of actually building and fixing things, not research alone. If you've got a question about any of the guides, the course, or the books, the forums are the best place to reach me.
