Last weekend I've heard 17 different callsigns and sometimes it sounded like a "dialogue des sourdes": Strong signals but they did not hear each other. Alarming is the increasing number of stations with good signals and mediocre receivers. It seems to me, that the real challenge on the LF band is the receiving part and I think there is still a lot of work to do. This includes also directional receiving aerials. I am aware of the fact that some locations suffer from heavy local QRM or Loran-splatter or have more Luxembourg-effect than others. On the other hand are receivers suffering from front end overload, inappropriate AGC-characteristics and large bandwidths far from the optimum. 73 de Toni
