How did everyone do? Me? Well... I, um, forgot that it was this weekend
until I tuned the bands. Sigh.
So, to make the best of it, I fired up N1MM+ and decided I'd concentrate
on 80 m. Upon checking everything out I findmy reliable 80 m DX antenna
(a F12 Sigma 80) was showing a 4:1 mismatch where it should be resonant
(around 3515-3520) and showing resonance near 3560. What!? Well, dang
it! It's acting just like my 75 m inverted V, which seemed suspicious,
but it wasn't identical. So, I didn't somehow screw up antenna
connections... On my morning walk I saw nothing unusual: no broken
connections, no damaged coax cabling, but it was very windy here a
couple of days ago, so I went out with a short step ladder to check more
carefully. All connections were good. But a more careful inspection
showed that two turns of an adjustable loading coil were touching,
shorting out a turn. After a minor adjustment, all was perfect. But....
The contest was over. So I got zilch.
