Today I learned about the posibilities of software defined radio in regards to shifting the frequency spectrum just slightly by changing the overall hardware clock.
This is an amazing (possible) feature - sometimes it is not feasible to air-gap machines - if the physical location doesn’t allow wires eg. - but this way there will at least be some security by obscurity! Read the article (it also has a nice video).
