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

[gosier at twcny.rr.com]

The Spanish 5 number stations have been on since the 1960s along with 
English and German versions. I was a Pop Comm reader and column contributor 
with Harry Helms back then. Some transmissions were believed to be Mossad or 
of Cuban origin. Also Jupiter , Florida and a military base there. They 
would start with a 3 digit number repeated several times a pause they 5 
digit groups. At the end would be a pause then "ende". 90% were done with a 
female voice. Also a split Spanish 3 with a pause then the other 2 digits 
was rarer but heard. Never has been a full explanation .....

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,
