What's New

Updates made to this site



24 July 2009

I have used a complete new site design and layout from Sepember 2008. The old site was becoming cumbersome and unwieldy due to the way in which information and pages have been added over the 10 years this site has been on-line and while I'm not entirely happy with this layout, it is a great improvement on the last version, and hopefully, easier to navigate.

Any remaining problems are due to the way my pages are collated and not caused by the excellent template, which was provided free by Andreas Viklund.

I find it amazing that many of the "oddities" featured on this site have been operating continuously over the 10 years since this site was started. Some of these have been identified and explained - some remain mysteries to this day.

Many of the emails I have received over the years congratulate me on the site. However, I am mainly the collator and custodian of much of the information and knowledge contained here. It is largely through the work and knowledge of shortwave listeners and enthusiasts around the world, building on the original core of information from the original ENIGMA group, that has made this site what it is today. My sincere thanks to all of you - you know who you are.



24 November 2007

A very long time since my last update. All   "Radio Links"   have been checked and updated, and obselete links removed. The   "ENIGMA 2000"   page has been updated with a recent newsletter and the latest Control List.

The   "Squeaky Wheel"  page has been updated to include the latest information.

Finally, The   "About Me"   page has been updated.



2 August 2004

A long time since my last update. Due to a move to broadband, the site now has a new address, which has been operating alongside the old one. The old site is now permamently closed.

The subterranea part of the site has been closed. It was originally my intention to develop the subterranea side, but this has now been done by others far better than I could have done.

I have added a short introduction to   "Numbers Stations"  , a short history of   "ENIGMA"   and an introductory page for   "ENIGMA 2000"   .

The  "Radio Links"   has been entirely rewritten and subject headers added.

Several new stations have been added, along with recordings, and most other pages updated. A new link has also been added to the "Woodpecker" pages.

Many thanks to ENIGMA 2000 for their help and support, and to all of those people who have contributed to this site - either directly to me or through ENIGMA 2000.



29 November 2002

A new article on "The Russian Woodpecker" from the 1980's. This topic still generates the most interest on the site, and I am pleased to be able to add not only the letter, but a plot of the signal to the website - thanks to Peter Martinez, the author and Chris Kirk, a visitor to the website who provided the article - My sincere thanks to both of you. Hope everyone enjoys this new article. Access from my "Woodpecker" pages or directly to the   letter and plot   from this link.

A new link to Scott Grant's subterranea site "uksub.com" has been added to   "Subterranea Links"   .




4 June 2002

All the sound samples of stations have now been changed from RealAudio files to MP3 format. Due to the updates made by RealAudio on their program, older versions of the program would not play new samples - a ridiculous situation. I was also never happy with the way RealAudio took control of your system.

Previously there was no viable alternative, since WAV files were far too large for web use. Now free WAV to MP3 converters are available, it is easy to obtain MP3 files from audio. An added bonus is that the files are now even smaller than the RealAudio files, should play quicker and you don't need to download the RealAudio player, which was getting huge!

Everyone should now be able to play these files. Please email me should you find any problems.

Updated link for "Abandoned Tube Stations" - Thanks for the email Chris!



2 October 2001

Another new signal added to the site. Called "Squeaky Wheel" . Have a listen to the sound sample to see where its nickname came from!

Two more sound samples have been added, One to "The Time Signal". , and another to the "Slot Machine" .

An alternative HAARP site has been added to the "Radio Links" page.




28 April 2001

Another well overdue update, thanks for your patience. Thanks also to all of you who have emailed with questions, answers and information.

The main news is that a new signal, called "Slot Machine" appeared in the closing months of 2000, and has been added to the site.

Next, the Home page for the site has been altered to make it easier for visitors to navigate around the site.

Finally, changes have been made to "The Time Signal". This signal is still heard from time to time, two more frequencies have been added but this can pop up anywhere from 3MHz to 7MHz (and possibly beyond!).




31 December 2000

This update is well overdue, and I thank those concerned for their patience, and apologise for the delay.

Great News - "The Grasshopper" signal has been positively identified. Visit the page for full details.

There has been a lot of interest in the articles on "The Russian Woodpecker" transmissions of the 1970s / '80s.
Thanks to all of you who emailed me. I have now been able to add another technical article on the signal, and a link to an article on the "Russian Woodpecker Hunting Club".

This is I believe, the only resource collection on the web for information on "The Woodpecker", thanks to all of the contributors for their assistance.

Finally, thanks to visitors to the site. The number of visitors has far exceeded my expectations.

Happy New Year to you all.
