TSA
Technical Services Agency - this page is a stub

Technical Services Agency, or TSA, was an electronics company that specialized in equipment for Technical Surveillance and Counter Measures (TSCM). The company was founded in 1974 by Glenn Howard Whidden, shortly after he retired from the Central Intelligence Agency (CIA), after 28 interesting years of field experience in covert operations. The company no longer exists.


Over the years, Glenn Whidden developed a number of products that were useful for finding eavesdropping equipment (bugs), starting with a number of add-ons for the Scanlock range of bug-tracers. One of his first products was the so-called COMPUSCAN, a fully automatic bug scanner that was connected to the Scanlock Mark VB. COMPUSCAN eventually evolved into Glenn's 'Eagle'. Other add-ons for the Scanlock Mark VB were the Spectrum Monitors SM-1 and SM-2. In the UK, some TSA products were sold by Audiotel, the developers of the Scanlock bug tracers.
