Assorted radio projects; the page on measuring balun loss is good.
Neat two-control ATU design. Making a better variable inductor (than I've currently got) would be the challenge -- note the wiper-on-toroid and variometer designs on this page... and also the air-cored coils at the bottom.

Wideband active small loop antenna edit / delete
Lower a loop's Q by adding resistance, then build in an amplifier: wideband magnetic-field antenna. Worth building to compare to my PA0RDT electric-field probe.

Including investigations into multiturn loops. (Aegis on #hamradio.)
KITE ANTENNAS G4ROJ edit / delete
And multiple kites. And aerostats. Wow.
Lots of random electronics: radio, including an unusual loop antenna; simple computer designs; why ECL should have beaten TTL; and various other bits.

Thought I'd bookmarked this before -- hm. Good stuff on antenna tuners and feedlines.

Why high SWR and feedline radiation isn't necessarily a bad thing (because it doesn't actually cause much loss in practice, and it lets you tune the antenna from the transmitter end).
Sort of a two-element log periodic?
