I experienced this Problem yesterday when I had my 2nd flight on Vatsim. Now I normally don't post questions on Forums I can answer my self by doing the research, but I can't find a answer to this.
It was either Schiphol Delivery or Schiphol Ground that was at a frequency with .xx5 ...like 121.975Mhz.
At first I thought the JarDesign Airbus A320 can't tune in to those frequencies, but it was the same thing with the FF 757.
So I assume X-Planes Com1 Radio can't tune to the 3rd decimal Number. Is that correct or what am I missing here?
I tuned in 121.980 and 121.970 but on neither Frequencies I could contact ground.
I can't remember from tutorials (videos or text) that this was ever mentioned.
Please help....
I didn't find the right solution from the Internet.
