[Ham-Mac] Unusual Aurora Communication

[Volker Grassmann]

Hi fellow hams,

Sorry for using bandwidth in this reflector. However, the discovery 
of the following propagation mode involves Mac software.

Radio amateurs report unusual Aurora communication which cannot be 
interpreted in terms of the scatter geometry which generally applies 
in Auroral backscattering. This phenomenon was analysed in detail and 
we found surprising results and evidence for new opportunities in VHF 
dxing.
