Bletchley Park archives will soon go online

As I’ve stated in the past, I’m fascinated by the use of radio communications by governments for espionage and wartime use.  When I came across this little nugget, I couldn’t resist.  What a joy it will be for those of us that can’t quite make it over to visit Bletchley Park.

The BBC has an article at:

Bletchley Park (really hard to resist using “BP” for this one…..) has been trying to do this for quite some time.  Dwindling funds, repairs needed for the site have just made this one of those “round to it” projects. Many documents are too fragile to handle at this time and will take awhile to get posted online, but it will indeed make for a fascinating online resource.

I’ve had the pleasure of actually getting my hands on  real, wartime Enigma machine and it was REALLY NEAT!!!  You can read about it, but there is nothing like actually using one to get you even more interested in this topic.  Professor Tom Perera gives a number of great discussions at the New England ARRL Division convention in Boxboro Mass (I spoke to Tom at Dayton and he said there may not be a presentation this year).  His site is a HUGE wealth of information on this topic (and CW keys).  If you ever get the chance to hear him give a presentation – JUMP ON IT!!!!

His website is:

More numbers stations/espionage information from Simon Mason

As mentioned previously, since I was a kid (long before being a radio amateur) I’ve been fascinated by numbers stations.  Every now and then I go on a search online to find more sites to satisfy my curiosities – there’s tons of ‘em out there.

This time, let me take you to the URL of Simon Mason, but he has a disclaimer about the material on his site:

The information presented in this section is for entertainment purposes only and does not disclose any information not already in the public domain. No assassination attempts are required! Thank you.

Rather tongue and cheek, but…… one can never be too sure!

His site looks rather old, but don’t let that discourage you – there is a TON of stuff here (and it’s updated).  Not only are there plenty of pages devoted to various numbers stations, but a plethora of videos and radio shows devoted to the subject.

Simon has written a small book that is freely downloadable on his website called “Secret Signals:  A Euronumbers Mystery” (available in HTML and MS Word format).

I can go on and on about the site, but just go check it out!  If you like this sort of thing, you’ll be there for hours!
