Actually I can confirm the frozen water don't conduct as well thing,
especially with RF. I used a puddle of water as a ground plane for a
transmitting antenna, once the water froze, I had a poor match, and
couldn't get out as well. But the rest is way off topic :)

This question begs for an answer from the two or three people
out there who have actually DONE some performance measurements.

Actually, it does have a small effect. I assume it has to do with a change
in resistance around the top load. It's not much, but I've noticed a

Temperature, humidity and barometric pressure will have little
effect, must be something else. Perhaps your ground connection needs
attention. Are you using a breakout point?
I assume that you are using an NST...........
Get to know the sound that your spark gap makes when it is working
well. When the spark gap starts sounding like a sick bumblbee then
you are not quenching properly and gap adjustment will be needed. It
is also possible to have a gap that is not quenching because of bad
primary tuning, then of course gap adjustment will not cure the problem.
My guess is that you have found the right primary tap point; that
your gap needs adjustment. Beware, large gap settings place heavy
loads on NST, and they are rather fragile.
