Being so near the Fall equinox I would
think that a DU signal would skew and arrive from an approximate SW
and NW heading if high latitude propagation conditions are
normal.

Forgive me for being picky, but the direction from Seaside to
Auckland is SE
of you, while the direction to Manila is about 298 degrees
or actually a tad
north of WNW !! However, the EWE has a wide cardiod
pattern and I just
modeled your EW in EZNEC and assuming an arrival angle
of 10 degrees the 3
db beamwidth is 140 degrees, so signal arriving from
73 away from beampeak
will only be down about 3.2 dB according to my
modelling. So it is your
proximity to the sea that is also helping you get
Philippine DX.
I've made all kinds of modelling changes to EWE's and
there's nothing funny
happening at least as far as EZNEC can model
it.
