Hi Razo+r and SHaDoW STeP BG,
Well setting the correct frequencies in the ME did the trick,
thank you very much for the help.
Though this has not much to do with what I intend under "easy communication"
but anyway.
No, no "auto" with the white text, but as soon as the right channel is selected,
the Airport to which it refers turns white.
Though, the text appears in BLACK, and sometimes in WHITE, regardless if it works or not.
Anyway... This leaves us with the QFE question. In other simulators I remember, like FSX and X-Plane, the barometric pressure is ALWAYS given by the ATC in QNH (e.G. 2992) because this is a number that you indeed can set on the altimeter. The QFE number can not be set on the altimeter, because it is always out of scale and requires calculations to be "converted" to a number that it can be set on the altimeter (e.G. 2992)...
Is it not so?
