It's really bad when you start commenting on your own posts, but here
goes.
Anyone who has been trained in safely handling firearms knows that
all guns are to always be considered as always loaded. The only
exception to that rule is when you open the weapon and see that it
really isn't loaded. The same thing applies here. Anything inside a
transmitter should always be considered as energized until you short
it directly to ground. Only then is it safe to touch. There is no
such thing as being too cautious with this stuff.

A resistor is considerably less reliable than a piece of heavy
gauge wire or braid connected directly to ground. You use the
shorting stick as a safeguard after everything is supposedly made
safe. If it's not really safe, then you live to tell the story
about the big bang and the blinding flash you saw when you hit the
HV with the stick. Much better than having others tell the tale of
you going out in a big bang and a blinding flash.

True, but should something be wrong with the meter following a
disaster, it might not show a charge. What an arc would be drawn
if 3 KV remained somewhere and you gave it a direct short.
I have always seen a high value resistor in these things.

If you do things right,
Power Down,
Watch the HV meters fall down,
Then - Apply the shorting stick,
There won't be an arc.
