On a quiet day I can see the 'FSK' of Mike's signal 100% on the screen and
would even give it a 'O' report, so it should be no problem to have a
slow-CW QSO with 2mW ERP (or even less) over a 350km distance.
So if you stick to slow-CW you don't need a few 100W and a big antenna to
get out of the country ...
