For anyone who is really interested in using Radio Navigation, "FS Tramp" and "Plan-G" are highly recommended, even if only the (Radar) Map function is used to obtain all the Airfield frequencies, and the Radio Beacon, VOR, NDB, etc, frequencies.
Also; its use as a "Radar Map" to observe the locations of other Pilots, when connected to Multiplayer, is invaluable!
...and what is even better....both programs are...."FREE"....
You will have ALL the radio frequencies at your fingertips...and you will never get lost!
Install one, or both, you'll not regret it!
