Why "impossible"?

More and more countries are opening 7100-7200 to their hams. In less
than 5 years the SWBC will all be gone. Non-split 'phone DX QSOs on 40
are becoming more and more common.

If someone over
there calls CQ and doesn't listen up, they get to work any
country they
want bar one, the USA, so why should 90% of them listen up?
Ergo, most of them don't.

Here's a clue: Many of them don't want just another Yank QSL. There are
so many US hams that if they don't "listen up", there's probably a very
good reason.

A lot of DX 'phones work split almost as a rule - not just on 40 but on
every band, as a way of thinning out the QRM and keeping their own QRG
clear.
