Almost a year ago I wrote a post entitled "A Simpler Field Expedient Rybakov Antenna for Winter". It is worthwhile to read that post to understand why I felt it necessary to make a winter version of a proven, tried and trusted antenna. My home turf is southern Ontario, Canada about 200km northwest of Toronto. … Continue reading Rebuilding the Winter Rybakov Antenna

We'll get back to the drinking straw question in a moment, but first let me describe another new project that took shape on the Ham Radio Outside the Box workbench recently - a QRP L-match.

In the last post we discussed using a backpack as a support for quarter wave whips or short poles. In that role it is gravitationally … Continue reading The “Titanic” 40m Field Expedient Backpack Portable Antenna
Major QMX Operator Flaw Exposed

But half a century later I make simple errors with my ham radio equipment. The fault is mine and not QRP Labs brilliant little QMX transceiver. In … Continue reading Major QMX Operator Flaw Exposed
Turkish Delight – QRP Style!
It was a long, long wait. I ordered my QRP Labs QMX factory assembled radio on the 9th of October 2023 and received it on the 4th of April 2024 - a wait of a little under 6 months. I guess I shouldn't complain, a fellow club member waited 18 months for his Elecraft KX2 … Continue reading Turkish Delight – QRP Style!
