Doesn't reciprocity assume similar antennas and similar
power levels? Of course, someone running the legal power
limit into a YAGI is going to be received well by almost
everyone but someone replying with QRP into a short
vertical whip is going to be at a disadvantage. Changes
in polarization in the ionosphere can easily explain the
above if one station is horizontally polarized and QSOing
with mobiles.
