Interesting theories and observations regarding one way propagation..My
take is that most of the seemingly one way prop is more dependent on
operator skill and the local qrn at one end of the circuit..With the
current conditions this past 12 months most usually strong signals on
the band are often attenuated due to less than a reliable path..I hear
many signals that may be only S1-3and few hear a station calling
them..These conditions may give the impression of "one way" prop but it
is more likely due to qrn conditions at the listening end...I am looking
at this from the VK cross the Equator Summer/Winter differences which
have a big influence on making a contact..My observations over 35 years
show that there is propagation most of the time all year if stations
take the time and patience to listen for DX..
