[NLRS] AirScout for aircraft scatter

[Barry VE4MA]

Hi Doug,

Thanks for sharing that. I still cannot get it to come up?   

What URL are you using for the server?

I see a lot of heavy air traffic headed to / from "the Orient"/ Alaska on a
regular basis....I am sure we could make good use of these planes for all
the bands up to 10 G at least...you proposal to chase contrails for optical
is very interesting !

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.

73, Doug Reed, N0NAS.
