@ai6yr It's a hobby. It doesn't have to make sense. It does sound like fun trying to set that up.

I'm a forty-five-year-old man, and I've been using desktop web browsers for twenty-eight of them, and only a few months ago I learned how to highlight text that is a hyperlink without clicking the link: by holding Alt why highlighting. I use it many times a day now. How did even use the web before that?

In case you still didn't know it, now you do.

Thank you @jhsoby for teaching me this.

@DJ5CW That's pretty much the same as I built here - I used all elements of the 18m mast, and the tuner is a Stockcorner JC-4s. I used the wire from some scrap dipole-ish antenna I had here and had to coil it in the lower segments since it was a few meters too long. (Should have measured it before putting it up. 😅) Radials will follow in spring when the grass will absorb them quickly. But it already works better than the FD4 I had before. 😺

@tk Stupid question, it's not just your rig set to a narrow filter with 500 Hz bandwidth?

@stripey I could probably read a very slowly blinking LED by "manually" decoding dits and dahs, but absolutely not at the 30wpm that I can hear.

@Stormgren the contesting answer to that question is https://www.qsl.net/ct1boh/2bsiq/ (no I can't do that yet)

Happy new year! During 2025 my all sky camera imaged the sky every 15 seconds, and this picture shows what happened in the sky. It shows the length of the night and day with the hourglass shape, the monthly lunar cycle with the diagonal bands, the elevation of the Sun at local noon, and lots of clouds.

The #hamchallenge is starting into its second year!

In 2025 we had 70 different participants who submitted 798 toots. The most successful participant was Ian, M0TRT (@ian) who completed 41 challenges!

Thanks to Phil, DL9PK (@phikes) for taking over the organization and operation of the 2026 edition. He rewrote the website, open sourced it (https://github.com/phikes/hamchallenge.org), and collected challenges for the coming year.

Here's to a successful second year, and thanks for all the fun we had in 2025!
