I had never seen Bob's book before but thanks to JC for posting that
link. There's a statement on page 93 which needs correction. Bob wrote
that he had examined several logs provided by Joerg DL3DXX (including S21XX)
and "I never found a single 160 meter long-path contact, NOT ONE!" Well,
maybe "not one" but actually three LP contacts with S21XX (SE direction
after NA sunset) that I know of (W4DR, N4SU and myself).

I was also surprised Bob omitted any mention of the N7UA <-> A61AJ (K1ZM
op) tests in November 2000 using 4-squares at each end of the path. That test
proved to me that the SW (post NA sunset) and SE (pre A6 sunrise) directions
were real and not an RX antenna problem. Note that this test was done prior
to publication of Bob's book in 2002.

Suffice it to say, we've learned much about this propagation
mode in the 15 years since Bob's book was published.
