Hi Scott,
Read your post with great interest. The filters you site seem to be on the
"pricey" side but... if they cure the problem after everything else
fails.... what the hell. The peace of mind may well be worth it! Anyway,
it's nice to know there is SOMETHING that works. GREAT!
But, by all means, please accept the counsel NOT to buy the filters for your
neighbors. THEIR equipment is poorly designed and that is not YOUR
responsibility to fix. You surely can show them what works (without
touching any of their equipment- unless you wish to take on the burden for
any new liability you may suffer as a result of having "touched" their
stuff) and have them either go out of pocket for the filters or petition the
product's manufacturers. Otherwise, you'll be shelling out for filters for
the whole neighborhood... and you shouldn't have to do that for equipment
that was poorly designed to begin with.
As for....... "No moles, no bees, no cling free, my antennas don't shine,
and I still don't
know where true north is. <G>" .... may I add... "Please put your hands on
the radio and say "Amen"."
73,
Roger, K2JAS
