[TowerTalk] Emoto Rotor

[Kelly Taylor]

Hi all,
If there's one thing we know in VE4, it's winter.

We've always recommended our locals lube their rotators with white lithium 
grease.

Generally, for those who keep their rotators in good repair, it's only on 
those really, really cold days (-44C) that the rotator slows even the 
slightest.

John is right, you only need a bit of lube -- as long as it stays on the 
bearings. You certainly don't want oil sloshing about like in your car.

Now, for a really important question, given that we're here and not in the 
thick of WPX: anyone know how to artificially excite the ionosphere? Don't 
know about you, but this weekend's MUF seems to have been just a hair over 
20 meters.

73, kelly
