Feeder on windows : never had to give the location

Hi,

I'm using the feeder software on windows and i'm surpried I never had to give my exact location.
It only asked me the closest airport.

Because he doesn't know where I am, the Polat plot on the premium page can't be correct ... it's the polar plot of the airport, not the one from the receiver...

I will get a raspberry soon, maybe the linux software is better ?
