BEACON HUNTING WITH MEDIUM FREQUENCY RECEIVER
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.
