One of my friends recently got a new radio (an Icom-706MK2G), and wanted to try the 15m band. We did not yet have an antenna for 15m, so it was a perfect excuse build another ground plane antenna (more details about the construction can be found here: https://m7isy.rootfs.net/2025/02/28/building-a-1-4-wave-ground-plane-for-20m/). It was the third time building this… Continue reading Debugging with a dummy load

Building, and then adjusting, the 1/4 wave ground plane antenna for 10m
Buoyed by the success of the 20m 1/4 wave ground plane antenna (the blog post can be found here: https://m7isy.rootfs.net/2025/02/28/building-a-1-4-wave-ground-plane-for-20m/), I thought that it would be trivial to build one for 10m. Simply use the exact same design, but half the length of the wire used, as that would mean it would be the right… Continue reading Building, and then adjusting, the 1/4 wave ground plane antenna for 10m
Building a 1/4 wave ground plane for 20m
I’ve been struggling to get HF working for me. I replaced the Yaesu FT-818nd’s internal battery, and figured out that there is a 11.5V threshold to get the full 6Watts out (more info can be found in my previous blog post: https://m7isy.rootfs.net/2024/12/06/yaesu-ft-818nd-the-11-5-volts-that-nobody-told-you-about/). I attempted to check my propagation by using the reverse beacon network and… Continue reading Building a 1/4 wave ground plane for 20m
