Notes:
a.     The message is composed of a 2 second long, 4 tone preamble followed by the stream of data;
b.     The data segment following the preamble is +/- 15 seconds in duration;
c.     Transmissions appear to follow a consistent start at the top of the hour (00) and bottom of the hour (30) with additional messages interspersed throughout; and
d.     The signal is potentially European in origin. Signal strength was observed to be very high and loud and clear from the University of Twente Wide-band WebSDR. Also heard on UK and Barcelona Spain KiwiSDRs.
