The goals of this activity are to operate an actual WWII radio, tune for signals, and identify non-directional beacons by their Morse identification.
Materials: A functional MF receiver such as RBA, RAK, RAL.  List of NDBs arranged by call letters.  Morse code chart.
Procedure:  After orientation, the participant tunes the beacon band.  On hearing a signal, the frequency and time are logged, and the identification written down as the pattern of dits and dahs.  The letters are looked up on a Morse code chart, and the station ID logged.
