#CQWW assisted and unassisted logs.
Evolution of the percentage of run QSOs in #CQWW, 2005 to 2025.
Says quite a lot about the state of things, doesn't it?
These are probably better indicators of long-term activity than the raw number of logs submitted for #CQWW.
Number of entries in #cqww over time.

#hamchallenge week 3: Understand how your antenna works. ๐งต
Let's check out the lowband vertical antenna I built before #CQWW in November. It is 16.5m long, built with an 18m Spiderbeam mast minus the top element. About 18m of wire are coiled up on it (for stability), and it is tuned at the feed point with a CG3000 automatic tuner. There are 12 ground radials with an average length of 10m below it. When I built it and laid out the radials, I noticed that the feed point impedance stayed at about 37 Ohm at the resonant frequency of ~ 4.1 MHz any more after 12 radials, so I left it like that.
