Yup -- It was a WW II system for both shipboard and shore usage. There was
a transmitter which sent different morse code letters in the various compass
sectors -- I think 30 degree segments. If a pilot heard, say, an "A", he
made a turn to either the middle heading for that sector or the reciprocal
heading. The signal would either increase in strength, or decrease, and
this would be evident by adjusting the volume. When he flew out of the
sector (off to one side), he would turn to regain the sector -- and this
might mean a false anaylsis, which would require a 180 turn.
In shipboard use during war, the codes would be changed every hour so as
to screen the ship location from the enemy. Shore stations didn't change
their code scheme, and the pattern was published in the enroute supplements.
The last one I can recall was at NAS Atlanta in the early 60s.
