During the great solar cycle of the late 1950's a VE3 neighbour of mine 
observed that on East - West 6m F2 paths a vertically polarized antenna 
often provided better copy than a horizontal antenna, while a horizontal 
antenna was always better on North - South paths. I suspect that one reason 
might be that the East - West paths tend more or less to follow lines of 
equal geomagnetic latitude, perhaps in ducts, while the North - South paths 
cross these lines and signals 'hop'. It would be interesting to be able to 
select vertical or horizontal or circular polarization from the comfort of 
the shack not only when working F2 paths but also when working long haul 
auroral Es, a case where the polarization of an arriving signal might be 
changing a fair amount - a speculation.
