Ward, one of the blessings of living here near Bangkok is that the ham
bands ARE EMPTY. No one cares about CW taking up half of the bands because
on any typical day there are two CW signals and one phone sig (not in
English) or just none, 160-10m. Big contests never fill up any ham bands
to the max on any mode.
Some issues are non-issues depending on where you are. 73, Charly
