Van Eck phreaking... It ACTUALLY works?!?!

i used to work with some crusty ex warrant officers and they told me that speaking the word TEMPEST outside of a secure area was court martial offence during cold war

Very nice demo of gr-tempest. Glad it worked for you! We're always interested in all kinds of feedback, so drop us a line if you feel like it.

Typing up a few notes on getting it set up in 3.10 I’ll share later. Very nice tool!

teh 15khz flyback & sync signals in an old style tv were real easy to pick up

Shouldn’t it be more efficient to point the LPDA with its smaller elements first?

Wasn’t the CIA/NSA using this on CRT’s back in the 70’s and 80’s?

Oh this is awesome

@LinusTech @linusgsebastian check this.

It’s surprisingly old tech. SCIFs have shielding for it.

Okay this is scary
