Just before I went on holiday I happened across a strange but faint transmission which I discovered was probably a Cuban Number Station. This perked my former interest into number stations and doing a little research I have found a number of audio documentaries, from several years ago, produced by the American NPR media organisation, most of them using Akin Fernandez’s Conet Project.
This last one was one produced and mixed by David Goren, and unfortunately the only audio available from NPR are in RealAudio format (shudders) but luckily David Goren has a SoundCloud page (his username Shortwaveology nice!) with high quality versions of the programs
I also installed Ian Wraith’s RIVET program which allows decoding of some of the HF data modes used by clandestine operators.
there is also the Engima 2000 Yahoo Group unfortunately this seems harder than the Freemasons to get into (just joking!) I tried to join just before leaving for my holiday and was then asked send a email back to prove I would be an active participant, which is reasonable enough request. I did send a detailed one back, to then be told they never received anything so I was denied membership, this seemed a little strange as all communication had been done using Yahoo’s own email system. In their defence I could have tried again, unfortunately I had neglected to save a copy of the email in my sent folder and being away on holiday at the time when I received the rejection I acted a little petulantly and decided I had better things to do.
