Firstly the band plan is the IARU Region 1 bandplan, reissued by the
RSGB to include local differences on frequencies above 430MHz. The
136kHz bandplan was agreed by the IARU and is the same in all Region 1
countries. At one time it was published as a 'suggested operating
allocation' rather than a rigid bandplan but that seems to have been
changed.
I know you have been on this reflector for many years. The bandplan has
been discussed here extensively (and fiercely) in the early days of
136kHz around the turn of the millenium and I could certainly dig out
some reference emails from my archive. There was a strong feeling to
keep the lower part of the band exclusive to CW apart from the small
area just above 135.8 to be used for transatlantic QRSS tests. I
believe PSK was used on the band at one time. Whether there is a need
to increase the current data area is open to debate, but the current
bandplan is exactly what was agreed by this reflector.
If you don't remember those discussions Mal I am afraid your memory is
beginning to fade.
