Hi Nick,
<<< I wonder if your best DX is coming in perpendicular to the cliff
face Gary? New Zealand hasn't been a frequent dawn enhancement visitor
in my experience, so your NZ DX may be influenced by the alignment of
the cliff. Of course, if Cape Perpetua aligns differently, then
that theory gets shot down.. >>>
Well, since this potent cliff-side TP-DXing boost was just discovered
recently, all the evidence so far is just circumstantial. To the best
of my knowledge, the Cape Perpetua site (south of Yachats, visited last
month) has a cliff which runs roughly north to south, with a
perpendicular angle quite favorable for both DU and Asiatic TP
reception. Because last month's DXpedition was conducted in mid-July
the Asiaitc TP's rarely appeared, but when they did come around their
signals were awesome. 774-JOUB showed up one morning (7-21) and pegged
the S/N readout on Norm Clark's PL-380 and 5" FSL
( http://www.mediafire.com/?nt0wgedrvd8qhvu )
By contrast the "Rockwork 4" cliff visited this week runs from the
northwest to the southeast, with a perpendicular angle directly at New
Zealand (for which it seems to provide a freakish signal boost).
Japanese "big gun" signals were completely disregarded by this cliff
until the very last day, when 666, 747 and 774 made a very anemic
appearance just before diving into the noise at 1300. These NHK signals
were not very welcome during my DU-prioritized trip, and fortunately
were easily nulled to allow continued DU-DXing. Despite this, if the
perpendicular angle theory proves to be true in predicting this
freakish signal boost, there are other ocean side cliffs among the 7
"Rockwork" sites which would be very favorable for Asiatic TP-DXing.
Cape Perpetua to the south has already proven that it is favorable for
such DXing (and will be visitied by hometown buddy Guy Atkins soon, for
Perseus SDR TP-DX captures).

Hi Nick,
Thanks very much for your daily TP reports during my Oregon Cliff
DXpedition (as well as those from Dennis, Steve, and Nigel). They
all provided a very interesting comparison.
The Japanese big guns (594, 666, 747 and 774) made their first weak
appearance at the "Rockwork 4" Cliff around 1230 UTC this morning,
but their signals' angle of arrival is directly in line with the
cliff face, and instead of boosting their signals the DU-favoring
cliff apparently cuts them way down. I was wondering why only the
DU's were coming in every morning despite the late summer date, and
this is probably the most logical answer. There are other sheer
cliffs at the site which would presumably favor the Asiatic TP's and
attenuate the DU's, if this theory proves to be correct.
73 and Thanks,
Gary DeBock (back in DX-deprived Puyallup, WA)

Still have recordings to go through, but here's a preliminary version
of what
was heard this AM, all Asiatic, at least so far. 1269 was a nice
surprise,
though has been heard here a couple of times before. I don't know what
it's
secret to success is, as Obihiro is inland. Ironically, I've driven
through
the town several years ago, and obviously should have checked out the
antenna
site, hi.
pretty darn good audio (all of it understandable by a native speaker,
at least
briefly):
none
reasonable audio at times during the period (much of it
understandable by a
native speaker, though often battling w/splash or noise):
1287 JOHR man and woman in JJ, fading up 1303UT //1269
1566 HLAZ 1300UT NHK style pips on hour, first time heard at 1300,
usually only
heard during earlier KK programs. As Dennis observed, this seemed
to have a lot
of dead air this morning, e.g. at various checks 1305-1310 with big
carrier and
no audio
not so reasonable audio, occasional words or phrases in splash or
noise could be
understood by a native speaker:
1269 JOHW woman and man in JJ //1287 at 1303UT; big surprise with
relatively low
number of audios this morning
Burbles in the splatter and noise (if lucky, language might be guessed
at by
cadence of talk, or parallel established by changes in talk or music) :
891 Asiatic talk?? 1305UT
954 maybe JOKR, too weak to tell 1258UT
Strongish het, no audio (either undermodulated or ravaged by splatter):
774, 1053
