At this point in the sunspot cycle, this hasn't been a big problem.
The Asiatic opening really doesn't begin that early in the afternoon. In CQWW
SSB, JA sunrise is around 21Z. 20 meters has been opening to JA around 21Z, and
15 meters, around 22Z. On 20 meters, 21Z is the tail-end of the European
opening. Once 20 closes to Europe, the smart east coast single-op stations know
they don't have a very good JA opening, so they either go multiplier hunting,
or
QSY to 40 to run Europe. This leaves just the east coast single-band 20,
multi-2's and multi-multi's on 20, greatly reducing the competition for band
space. They quickly discover that I am working 2nd and 3rd tier stations they
don't hear at all, and usually leave me alone. I have much bigger problems with
Caribbean and South American stations suddenly showing up on my JA run
frequency.
On 15 meters, this has been even more of a non-problem. There isn't much of an
east coast JA opening on 15 at this point in the sunspot cycle.
This was a little more problematic during the peak of the sunspot cycle, but
the
secret was to run JA on the highest frequency band that was open for me at the
time - which is usually a higher frequency band than the east coast has an
opening at that same time.
