The description from the Spybuster datasheet is a bit vague, but it looks to me like they are analyzing aircraft transponder transmissions in order to warn of nearby aircraft of any type. Let me quote from their brochure: "The SPYBUSTER(TM) is truly a star wars device. Over three years in design and development by the man who invented the Fuzzbuster(R), it will do what has been considered impossible...IT WILL DETECT SURVEILLANCE AIRCRAFT! Now you can defend yourself against this ever expanding menace." "The Federal Aviation Administration's new radar system now keeps track of virtually all aircraft in U.S. airspace. The SPYBUSTER(TM) utilizes Big Brother's own signals to automatically alert you to the presence of surveillance aircraft. This unique and highly sophisticated operating principle makes the SPYBUSTER(TM) effective and LEGAL throughout the country." The price of this wonder is $279.95 + $3.00 s&h, and you can order it from Electrolert, Inc., by calling 1-800-543-3848. Disclaimer: I'm not associated with Electrolert, nor have I ever even owned one of their products. But this one sounds pretty useful, especially here in central Florida, where the FHP, Orange County Sheriff, and even some two-bit local police departments all use fixed-wing aircraft for speed traps (the FHP nailed me near Tampa several years ago for 77 in a 55 with an aircraft). -- Computer Fenestrations Bob Breum Post Office Box 151 {uiucuxc|hoptoad|petsd|ucf-cs}!peora!cmpfen!bob Lake Monroe, FL 32747 USA +1 407 322-3222 "C is the new BASIC"

I have been in states that have sky patrol, and when ever I have seen them it's been in a remote area so I doubt if they even bother to tell ATC who they were, and I doubt if ATC would even care if they did, unless they where setting a speed trap in a controlled area. I wonder how often it's going to start beeping at some student pilot out on a cross-country. -- Jack Computer Support Corportion Dallas,Texas Hudler UUCP: {texsun,texbell,attctc}!csccat!jack
