"If we knew the arrival
angle of a received signal during
an enhancement, we could visualize
the phenomenon more clearly"
I often seen post-sunrise enhancement using an inv-V with
apex up 30m (<0.2 wavelengths and peak TOA straight up). I believe
we have the same enhancement from stations in EU/Middle East/AF
at their sunrise who are using marginal (i.e. high-angle) antennas. This
may be some sort of high-angle mode which injects the signal into the
ducting region. Your results might have been very different if you used
high-angle RX antennas for your tests.
