That never stopped the SSB and AM boys for years ... they always
crowded right down to 1830 to talk across town because "that's where
their antennas worked". The same thing is going to be true for the
JT65 users - they're not going to deal with two segments/retuning
antennas when they will work anything that comes along.
That's a fact of human nature.
