So, Holger, if you arrange that all radio transmission packets in FG/MP
carry the transmitter's wattage and the location of the source, you can

out the straight-line distance from yourself

Hi all,
sorry that I had breaking off my activities for voice communication for
FlightGear the last months... I was ill and had pretty much to work. Ok,
I have anymore much to work...

No such constant number. It highly depends on

Hello *,
ok - that was one of my typical need only one parameter question :-)
I see that this is not so easy as I thaught... but it is not an
insolvable problem. I think I will put a more or less complex formula
