We used to follow a band plan, formal or informal, in which digital modes, primarily RTTY, operated above 7.060 and CW below in the 40 meter band. I work CW primarily. We also used to listen before transmitting and would never knowingly interfere with another station already in operation. Now, I can't find a spot not occupied by a RTTY station, and if I do, it's a sure bet a RTTY station will tune up and start squawking over the top of me. Are band plans and operator courtesy no longer in operation on 40 meters?
