[Spooks] Spooks Digest, Vol 78, Issue 26

[Beaumont, Paul]

The affidavit describes the Radiogram as:    'Radiograms are coded bursts of data sent by a radio transmitter that can be picked up by a radio receiver....'  It carries on, 'As transmitted, radiograms generally sound like the transmission of Morse code.'

That sounds to me like XPA polytones - automatic decodes. So the clicking may well have been laptop keys being operated - unless they hear the same click, or tick, I sometimes hear when I receive XPA.

The FBI complaint, as hosted by the New York Times, is here:

http://documents.nytimes.com/criminal-complaints-from-the-justice-department#document/p30

On page 30 (in the NYT document reader) the FBI claims that their audio
surveillance of the Yonkers house in 2003 yielded, on "at least five
occasions", "irregular electronic clicking sounds associated with the
receipt of coded radio transmissions."

I don't know how radio transmissions are supposed to "click", that sounds
like 19th century telegraphy, but if it's Morse it makes me think that they
were decoding either M08a. Since another Cuban station, V02a, has been
implicated in a Federal case against Cuban spies, it doesn't seem
unreasonable that the same transmitter might be contracting for Russia as
the M08a format.

So, does the new Cuban format, SK01, displace the schedules of M08, V02a, or
both? If it's one or the other that's evidence for my hypothesis, if both,
then it's evidence against.

But shortwave doesn't seem to have been an important form of communications
for them, the FBI complaint only mentions it in passing. Mostly they were
using ad-hoc wireless networks between laptops and steganography--encoding
text files in images on the Internet.
