Proper use of the ADF
1) Select NDB as waypoint on GPS
2) Enter desired track to waypoint
3) Fly the little white airplane up the magenta track
4) Tune ADF to 60's Rock and Roll station
5) Enjoy better flying through high technology and the last decade of good music
Really with used portable GPS units available for the same price as a good headset, I do not understand why pilots deprive themselves of the most accurate positional and navigational information available (backed up with a map of course).
