        Maybe a bit more...the photo on the July 80 CQ Cover (at
http://members.aol.com/ve3bmv/Razors.htm ) shows two Razors with the
TH-6 half-way between.  Give a single Razor a 3 dB advantage (>3dB
gain minus TH-6 trap loss) for the Razor's 60 foot boom versus the
TH-6's 24 foot boom and add 3 dB stacking gain for 6 dB total...seems
about right to me.  With the TH-6 almost halfway (...but not exactly)
between the Razors, terrain effects should be mostly out of the equation
since both antennas are about the same average height.

        One other correction to Yuri's claim about being the only
North American station to work the QRP VK0...I believe WA1AER (now NR1R)
also worked him...and there may have been others as well...just to keep
our facts accurate.
