Topband: N7NM's book

[Hugh Valentine]

I have QSL from S21XX when I had the big antennas and many long beverages.
Feb 08,1997 @ 2342Z  80M CW.

I did not record the path in the computer log, but it was a special QSO.
If that can be extrapolated to mean anything from Georgia.....just adding to conversation.

     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.
