Launchpad in a Dry Tree: 75 Watts, No Solar Noise, and a Lesson in Spacing

Published: Sep 24, 2025

The Setup

I turned a dry tree into a launchpad for my signals using a 10m vertical built from a fiberglass pole and thin wire. With a CG-3000 tuner managing the match and five radials spreading the RF, the system sang. The YAESU FT-891 provided 75W output power by using a 12V car battery, while the 9A5N Solid State Paddle provided the finesse.

The QSO with DF1ZA

Despite the storm, things went surprisingly well today — aside from the frozen fingers, of course! There is actually a silver lining when the sun refuses to shine: the neighborhood solar inverters stay silent, leaving the bands blissfully quiet. (Title for my next book: “Why I Love Bad Weather: Cold Hands but Zero QRN!”) :-)
Attached two pictures to show the antenna setup.

The session with Rüdiger, DF1ZA, was a highlight. With a steaming mug of hot coffee acting as my co-pilot against the wind, the QSO flowed smoothly. But the real value came afterwards, when Rüdiger kindly sent me an MP3 air-check of our contact.
There is nothing quite like the experience of hearing your own ‘fist’ from the other side. It was a fascinating reality check; listening back, I realized that while the characters were solid, my rhythm would benefit from letting the code ‘breathe’ a bit more. A fraction more spacing between words, and the copy becomes effortless - or at least better ;-) . Always learning!
