If you're hungry for updated, practical electronic circuits, this is a beggar's banquet. Not only do these ingenious circuits - some never published - really work, but they're simple, inexpensive and... This description may be from another edition of this product.
A good read, great circuits to build and test....good technical book to refer to.....
Bench-Tested Circuits : For Surveillance and Countersurveill
Published by Thriftbooks.com User , 23 years ago
My buddy and me used some of the circuits from this book and his second Bench Tested Circuits book and were able to fool a high priced Counter Measures team with a big van loaded with CM equipment. We were in some god forsaken town that only had a Radio Shack and a Hardware store. The circuits are simple but work just as well as the more high priced circuits that we have seen. Many of this guy's simple techniques are almost impossible to detect. Our client was very happy when he listened to the chatter from the CM people.
I found some very interesting and overlooked circuits here!

A friend of mine and I were very impressed with his simple Subcarrier Converter for transmitters and his SCA decoder using a very common, mid-price range communications receiver. We have never seen such an unusual and highly effective technique for preventing the casual listener from over-hearing covert intercepts. Some of the other books like Basement Buggers Bible (though really great and with much more detailed plans), for some reason, did not have some of these more sophisticated modulation schemes. His simple Carrier Current By-pass technique really worked well on a recent case. We found the Capacitors that he recomended for the By-pass at a Ham Fest (they were a little hard to find though)...
Very useful circuits!

As an electronics technician in the security field, I found Mr. Larsen's circuits well described and very clever! They are sophisticated yet simple for the average tech (like me) to build. Some of the circuits are unusual and I have not been able to find them elsewhere!
