Lower & Longer! The 160 m Dipole Tune-Up

Lower & Longer! The 160 m Dipole Tune-Up


A simple job that somehow took all afternoon! Today I’m re-tuning the 160 metre leg of my 80 / 160 fan dipole — dropping the resonance from 1.94 MHz down to 1.85 MHz where the amp is happiest.

I’ll show how longer = lower (it still catches me out sometimes!), explain why the UK full-power segment matters, and talk a bit about impedance, quarter-wave 75 Ω sections, and matching tricks for low NVIS dipoles.

Original Build: https://youtu.be/PV5GdAZ1nfo

Expect the usual chuckles, dog balls, and unexpected wander into the woods…

Gear used: DX50 Kevlar wire, 75 Ω coax, analyser, and a mug of tea.

73, Callum – M0XXT

Calling CQ from the Welsh Mountains

Calling CQ from the Welsh Mountains

During my vacation in Wales, I teamed up with Sandy (W7NRS) and Kevin (MW0KXN) for a Summits on the Air activation in the Welsh mountains. The hike was amazing — rolling green hills, farms scattered across the valleys, and even a view of the coast way off in the distance.

Kevin went above and beyond with his hospitality. He brought all the radio gear, handled transportation, packed snacks, and even got the word out to local operators so we’d have plenty of chasers waiting for us.

It was an awesome day of hiking, radio, and friendship — a true SOTA adventure in one of the most beautiful places on earth.

Half Wave Vertical Readings (Short #100)

@rickbammesberger1721 is experimenting with vertical antennas. The antenna he is using is giving him strange SWR. What could be resulting in such strange readings?
