Re: [Propagation] Beam heading maps

[Jim Smith <jimsmith@shaw.ca>]

DX Atlas will give you an azimuthal projection map for any spot on the 
face of the earth, including the one you live on.  It will also give you 
grey line, F2 and E critical frequency contours, MUF contours, aurora 
coverage, D layer peak density contours, a DX gazetteer, CQ and ITU zone 
and Maidenhead grid overlays and lord knows what else.  Grey line makes 
a lot more sense when seen on an azimuthal projection compared to that 
weird wavy line you get on the typical rectangular projection.

You can accept SFI and auroral indices from the built in model or from 
the internet, or you can enter your own values.

If you haven't had a look at it, I think you would find it worthwhile.  
You can learn a lot just from playing with it.  Watching the gray line 
in the azimuthal projection it becomes instantly obvious why signals are 
coming from one part of the world and not another.

The only problem I have found with it is that it made it obvious that I 
needed a 2nd monitor so I can display it all the time!!

Hmm... sounds like an ad.  The usual disclaimer applies.  I'm just 
really happy with it.
