If you’ve ever tried to find a hidden radio transmitter, or if you’ve ever wanted to…or if you’ve ever wondered how close you could get to finding a “jammer,” this month’s Lecture and Lab is for you!
We’ll be building the KC9NON active attenuator kit, an easy-to-build device that lets you get up close and personal with the radio transmitter that you’re hunting. The kit cost is only $20.00, and the tools needed are simple: a soldering iron, solder, wire cutters, wire strippers, and a small screwdriver are all that you really need. A hot glue gun and a needle-nose pliers were enough for me to finish my build. You’ll also need a jumper cable with BNC connectors (it can be very short, 2 feet is plenty), and a BNC-equipped antenna and radio, or else a set of adapters.
We’ll be meeting at 10:00 AM on Saturday, September 23rd, in the 3rd-floor community room at the Dallas Medical Center, 7 Medical Parkway Dallas, TX 75234. There are 15 kits available, first-come-first-served.
