it's quite pointless to give out "of the Year" awards on Jan 2nd anyway:))

They'll both be out from top 100 by the end for sure:)

But if I was Yuri, I would think twice next time attacking Tom again. It's
kind of sad to see a honorable ham like Yuri letting himself down with such
childish attacks day after day as if he had some strange subconscious
umbrage at sth Tom's done.

As far as I am not aware of what it is I'd be very interested in reading
rather Yuri's topic related comments and fashinating descriptions about his
novel antennas than equalling K3BU at the From line with another probable
offence towards somebody and disregarding it.

If you wanna prove Tom's wrong then there are 100 more intelligent ways to
do it.

wish hny and a lot of enjoyable threads to everybody...and more tolarance
