Subject: [TowerTalk] 80m 4-square advice...
I'm finally making some progress towards installing my 80m 4-square and
looking for some advice before I finalize the installation. Is anyone out
there using the Comtek system tuned for 3.650?

I would appreciate any feedback that could be
offered before I decide which segment of the band to tune for. My
radiators here are full size 3" irrigation tubing and should theoretically
produce about 300 khz at 2:1.

Many thanks in advance.
