Topband: Impressive demonstration of one dB of signal strength improvement

[K9FD]

Martin I am sorry I do not know when that article was published,  I have 
moved QTH and
gave away all my old QSTs.   Will try and find it in the on-line 
archives,  but think you have
to be a member to read those archives.   Perhaps someone knows where 
else it could be
found.
