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. 73 Dave G3YMC http://www.davesergeant.com
