[Elecraft] [OT] Strange signal on 17 meter CW

[Oliver Johns]

Hi,

This afternoon, Saturday 9 March 2013 at about 5pm PST (approx 10 March 01:10Z UTC), I heard a strange USB signal in the CW portion of 17 meters.  The frequency was 18.07415 MHz.  A recorded female human voice was reciting a string of five-number codes -- in Spanish.  Like 94514 65443 98713 ... .  This went on for some minutes (I don't know how long it had been going when I first heard it).  Then it stopped and was replaced by some sort of multi-tone signal.  Then that stopped, and the transmission ended.

Did anyone hear this?  Is this something that is well known?  I ask here since this list is full of attentive CW operators one of whom might have heard it.

73,
