The Electronic Surveillance Circuits you will find on this site are unique and can not be found anywhere
else on the net. The enclosed electronic circuits, are but a handfull - out of thousands, that have been designed,
engineered and - for years, manufactured by John S. Wilson Jr, who has a proven track record with over 50 years in the
Design, Engineering, and implementation of Electronic Surveillance Circuits, both in the lab and the field level. All are Free.
