First reported in late 2009. This odd narrow band pulsed signal jumps around a center frequency in 100Hz or 200Hz steps, and will also vary the pulse repetition frequency. Pulse rates of 11, 22, 33, 43, 55 and 76ms have been reported. Signals are frequently jammed or overlaid with another wider bandwidth interfering signal.
Bearings taken indicate a possible origin of Cuba or Southeastern US.
