Dear Bob, LF group

assumes that the EU band plan can not adapt to demand.
73, Bob ZL2CA
Some aspects of band use are not within the power of amateurs to
do much adapting to - for example CFH and SXV can transmit
where and when they like in the band, as can the intermods that
plague some parts of Europe.
The other thing is that the long distance/exotic modes activity is a
minority interest among LF amateurs - it is not really reasonable to
fill a large portion of the available band with signals that most of the
band users cannot make use of. There has already been more than
enough debate as to whether this is good or bad, but there it is.
So I think operating in small bandwidths is an inevitable part of the
challenge of LF; it has certainly proved useful with the current crop
of QRSS type modes, where virtually all the beacon activity has
fitted easily into a bandwidth as wide as a single CW signal.
