"Mils" or "Miles" ;-)
Anyway, that is too far.

Well, I wouldn't consider them "inconsiderate": I consider them damned annoying and totally
inexcusable.
Now, despite that statement, I DO know that there are certain strange propagation conditions
which actually add clicks to a perfectly good signal. They almost sound like an echo, in fact.
I only wanted to make sure that anyone who "has" clicks, really does have clicks, since it is
so easy to mistake other things for real clicks.
