| On HF, if other operators are using the designated net frequency just before the start of the net, the net controller can ask them to relinquish the frequency for the net operations. Although they should move to a different frequency as a courtesy, they are not obliged to. In this case the net controller should conduct the net on a frequency 3 to 5 kHz away from the regular frequency so that regular net participant can easily find the net without causing interference to the others using the regular net frequency. | On HF, if other operators are using the designated net frequency just before the start of the net, the net controller can ask them to relinquish the frequency for the net operations.

| * But more importantly: there is NO //one// Azimuthal map. Instead, everyone needs their own with their location at the centre. These maps only work from the centre outward. You can't use these maps to find the distance and direction between two off-centre points. This is one case where putting yourself at the centre of the world is necessary. | * But more importantly: there is NO //one// Azimuthal map.
