[Discuss-gnuradio] "Tempest" for LCD displays?

2005-06-19 Thread David P. Reed
I find it amusing that the idea of using a CRT output to radiate AM and FM band signals is called "Tempest", since it is really anti-Tempest (or inverse-Tempest) (the US gov't security specs called Tempest specs when I was working on DoD security research in the early '70s were designed to prev
