Progress made in detecting STI?

[computersoc]

Has anyone tried with or without success on detecting the STI using a similar concept as the Spectre III does?

With the STi, there's really nothing to detect, other than some weak signals somewhere in the 400-500 MHz range, nowhere near the frequencies RDs operate at, and RDDs look for.

A STi detector would have to be custom designed specifically to detect the STi, and then there are countless other devices (i.e. pretty much anything with a microprocessor) that also emits signals in the same frequency range... just about everything would set it off.

Therefore, at present, there's no way to reliably electronically detect the STi.

Do all RD's emit in that same range, or is it something unique to the STI?

Well, the STI's so well insulated that the typical RD emissions are virtually nonexistent. The 500mhz leaks could very well be just the display or some power supply equipment, but from all I've seen about STI leakage nothing can qualify as a "signature" that has a remote chance of identifying it as a STI.
