[NLRS] AirScout for aircraft scatter

[Doug Reed]

I received a reply from Frank, DL2ALF, the AirScout author this
morning. He said the program should work as long as I set the plane
area correctly. I made the changes again and this time it is working.

I know I made similar changes before, but perhaps I reversed
something. All I can say for sure is I made the changes again and the
display is now showing planes moving around the area needed to make
the path I requested.

Specifically, I asked for the path from N0NAS to K0CQ, that being two
calls that first came to mind. They both populated location info
automatically.

In the Options/Planes page, I set:

Minimum altitude 1000m
Maximum altitude 20000m

Minimum Longitude -100
Maximum longitude -70
Minimum Latitude 30
Maximum longitude 78

I also hit the button to "Clear Positions" which emptied the plane
database of the European position information. Then "Apply" and "OK"
to exit. The map showed the correct locations and planes appeared
after I started the program running.

The plane area above is much larger than the area I'll be looking at
on the map. The numbers were chosen to cover most of the midwest and
are near the maximum size allowed for a download from the Globe
elevation database. You have to do that download manually from the
Globe web site mentioned on the Options/Globe page. OTOH, I'm still
not seeing elevation data.... I may need to try again with a smaller
area.

I still don't know what my original error was, but AirScout is working
fine for me now. I also tried changing the path to N0NAS and VE4MA,
and that worked immediately too.

But I'll warn you, if you drag-and-drop to change any station
location, it will remember that change and use it next time you
request that station. Even if you do QRZ lookup again, it will use the
location you changed to, not the one in the QRZ database. I tried
using call sign options like /p and -1, but it tries to validate them
against QRZ.com and will not use them if the data doesn't match or
doesn't exist.

I switched back to the default 4000m and 12000m altitude numbers and
everything still worked, and the active scatter region on the map
became smaller as it should.

I think the best thing I can say is that there seem to be regular
flights from Winnipeg to MSP and Winnipeg to Chicago, so planes seem
to stay on the desired path for long periods of time which should make
plane scatter fairly "easy" for that path.......

So try it again guys and see if you can get it working. It does seem
to be working for me now.
