Huh? / Re: Different themes for the forum?

Dark Reader is a popular open-source "dark mode" extension available for Chrome, Edge, Firefox, and Safari.

Ya' might have to tweak the settings for your own preferences, but otherwise it does tend to work okay on many sites.

Equipment / Re: 9:1 unun, end fed antenna
« on: February 09, 2025, 2247 UTC »
You might also checkout a end-fed half-wave if you want to target a specific band (and its harmonics). 49:1 and 64:1 are popular unun ratios to try.

Awhile back I deployed a temporary ~7MHz EFHW horizontal mounted a few feet off the ground more or less for NVIS reception. It works decently for the usual 43m pirate band with just a Tecsun PL-330 or ATS-20+ receiver for some background radio on the back porch.

BTW, while currently out of stock, eddieson (KG6ZBN) on eBay often has EFHW end-fed transformers for ~$15 shipped. The designs are subject to change, but the link is usually:

I have had good results with his various EFHW transformers, and the price is quite decent compared to DIY unless you buy the various parts in bulk.
