His extensive coverage of various topics on his YouTube channel was inspiring, and you can see his influence throughout These Pages, such as the VK3YE inspired L-Match tuner.

QSX Update and Winter Project Ideas

Most of us have been waiting patiently for the QSX, but some have been waiting a little less patiently. Unfortunately this has put a lot of pressure on Hans over at QRP Labs, but he’s stood his ground: It’ll be ready when it’s ready, because quality comes first. And to that we say, bravo! Given …

Project Brownie Begins

One of my greatest joys of ham radio is repurposing things. It doesn’t matter if it’s a fishing pole for an antenna or stripping out old CAT5 cable for experimental wire antenna, or using fittings from old CBs. Earlier this year I found an old AM/FM clock radio that I stuffed my DC40 project into. …
