4.0 out of 5 stars The Secret Listeners, 6 Dec. 2012
Verified Purchase(What is this?)
This review is from: The Secret Listeners: How the Y Service Intercepted the German Codes for Bletchley Park (Hardcover)
The Secret Listeners: How the Y Service Intercepted the Secret German Codes for Bletchley Park

This book is an interesting compendium of views, thoughts and events that surround the Y Service personnel; sadly little technical info.

The information seems good; I have read a lot already on the Y Service as well as having an unhealthy interest in Wireless Interception and RDF.

The book was an easy read yet prompted me to pick up my dictionary and thesaurus occasionally. I read one chapter at a time and on more than one occasion one became two. A worthwhile read.

However, I have one small correction to offer. By the image of the 'Doughnut,' the new GCHQ building, Mr McKay authoritatively states that Morse has had its day and that GCHQ no longer intercepts it.

I would beg to differ; I follow Cuban DGI [their intel service] Morse transmissions daily; three messages sent over ~35mins and they're not the only ones. Last Saturday's RDF bearing was ~260deg. [Give it a try: 5898kHz at 0500GMT and 5800kHz at 0600GMT, although there have been some gaps as they seem to be switching to a Hybrid Mode that uses a mixture of Spanish Voice and RDFT data]

Even the Russian FSB send Morse messages to their operatives abroad.

There's also spoken message form as well as a pseudo data form, the polytone. And there's more.......but that would be another story.

All in all, a very good read for someone who knows a little about the subject.
