[Ham-Mac] Amateur Radio Propagation Studies

[Volker Grassmann]

Hi fellow hams,

Four new articles await your attention:

- the aspect angle in DK3UZ's and UA1ZCL's Aurora QSO shows the 
largest ever observed deviation from perpendicularity
- we discuss OH5LK's dx observations high in the north and ...
- we examine the Doppler effect in Aurora QSOs
- finally, we analyse unequal propagation path lengths in bistatic scattering

If you are looking forward for a BeamFinder version supporting the 
Mac OS X operating system, you are requested to proceed to the 
announcement in the BeamFinder news.
