        I've updated DX Aid plots to show the following 160 QSO's:

Local USA sunrise long path QSO's at ~210 degrees true:

    W0ZV to UA9UCO...29 September 1987 at 1234 UTC
    W0ZV to JJ1VKL/4S7...28 December 1991 at 1337 UTC
    N7UA to A61AJ...26 November 2000 at 1504 UTC
    W4ZV to 3W5FM...6 January 2000 at 1145 UTC
    W4ZV to XZ0A...21 January 2000 at 1155 UTC
  
Local USA sunset long path QSO's at ~150 degrees true:

    W4ZV to 9V1XQ...13 January 1996 at 2309 UTC
    W4ZV to S21XX...4 February 1997 at 2320 UTC

        These are available at:

Please click on the QSO of interest and then hit the "Back" button on your Web
browser to return to the index page.  Hopefully you can see the similar pattern
to these...especially the sunrise QSO's which are from 3 different areas of the
USA (Washington, Colorado and North Carolina).  Signal azimuths are amazingly
consistent and independent of the target location.  This is also characteristic
of 80 meter long path propagation which is much more common than on 160.  See
the Force 12 page I referenced previously for a very interesting story about
75/80M long path from California.  In my experience, 160 propagation follows
exactly the same pattern seen on 75/80 except that signals are much weaker.
