The majority of operators over th= e years prefer=20 CW on LF and MF. These bands are narrow and we do not want th= e=20 few Khz available cluttered up with data modes, especial= ly=20 Beacons.
Those countries with several Khz= allocated like=20 the USA have sufficient space to provide slots for all modes, diff= erent=20 story.
I am on LF and MF daily using nor= mal CW if you=20 would like a QSO.
