Hello Matthias!

Just curious, were those problems that you spoke of with a fixed frequency?
I'm just trying to learn more about the "sweep-fequencies" that I spoke of in
my reply earlier, to trying and learn if anybody else has considered this
ultrasonic technology...and if it addresses the issues you speak of...

PS - Just got initiated to Tulsa severe weather tonight...thunder that shook
the whole apartment building I'm in like a earthquake (well, as a California
kid I'm kinda used to that...it just wasn't so LOUD is all) BUT, I'm not used
to seeing ice "golfballs" falling outta the sky...WHEW! As I click my ruby
slippers; "There's no place like home Toto, there's no place like home..." (a
nervous; "hehehe"....YIKES!)
