There are a number of illegal short wave broadcasts that are apparently
difficult to track down (as to location).  These broadcasts consist 
entirely of numbers (as far as I have heard at least).

My question to the net (particularly to the sci.crypt experts) is 
simply what type of encryption schemes are employed by these "air
pirates"? The one station I've recently heard (its been a while
though), transmitted numbers of a fixed length of about 5 or 6 
digits each (in morse code).  These numbers obviously mean 
something to somebody :-)

I have no cipher expertise but this has me somewhat intrigued.  Anybody
care to shed more light on this subject?
