[Spooks] Morse code numbers station

[mslaten]

Hi B Paul Patterson:

    You have indeed copied a Cuban M8a transmission.  It is a daily 
transmission on this frequency.  The first broadcast is at 1800 UTC and the 
repeat broadcast is at 1900 UTC.

    As has already been mentioned, the encryption is probably by "one-time 
pad".  This is also not likely to be decrypted unless you are the recipient 
and in possession of the proper pad.

    You can break out the 5-figure numbers to their correct identity though. 
The Cubans use "cut numbers" to transmit their morse messages.  In other 
words, the numbers are represented by letters in lieu of numbers.  This is 
the breakout for the numbers:

1    =    A
2    =    N
3    =    D
4    =    U
5    =    W
6    =    R
7    =    I
8    =    G
9    =    M
0    =    T

    The purpose of cut numbers is to be able to send the message in a 
shorter time.  If they used the morse equivalent of the above numbers, it 
would take a bit longer to send.

Howdy,

I'm not sure if anyone still uses this list for discussion or not, but I
suppose it's worth a try.  I just started SWL'ing, so bare with me.  I
picked up a numbers station running morse code: 8097kHz 1900-1935 UTC
3/15/08. Downloaded some software quick and started transcribing it.  Here's
what I got:

I was just wondering if anyone out there knew anything about this particular
station and more importantly if there's any way to decode it.

Thanks,

-----------------------

    In your copy of the above message, you began your decode in the middle 
of a message.  The first three groups would read as 44950 87999 99378 etc. 
After the AR AR AR (AR = end of message), the "iwaid" repeat five time would 
be the addressee for the next message.  This would equate to 75173 repeated 
five times then the "=" or BT, and then into the next 150 group message. 
Then the AR AR AR SK = (end of message, end of transmission).

    The Cubans usually begin their skeds on the hour.  They normally call up 
three addressees, (in this case the were 35108 66842 75173), as I also 
logged this sked.  You began your decode about halfway through the second 
message.

    Hope this helps, and look forward to seeing more of your logs.
