I never said 50kW was not enough power to satisfactorily receive DRM, it was a value based on the reception of a very limited number of DRM stations in a consumer environment using a whip antenna (not the best antenna in the world, but one used on nearly every portable radio and probably the only antenna used by a non-enthusiast consumer).
Maybe living in the northern latitudes is not the best place to be, I am sure tests further south would be more fruitful

If these days 50kW is not enough for satisfactory reception - noone will ever run up to 5MW DRM on shortwave!!!
