MAGNETIC -WAVE U.P.0. Detector : The magnetic wave UFO Detector is different from the " Compass needlcl tog, in that it doesn't rely on mechanical movement, which intruduces inertia, thereby lowering overell sensitivity. In ». e of the compass needle, a 20.000 Ohm coil is used( for exemple an old el Reloy). This coil ig 4 connected to the high impedance input of the A, Lifier YAA 151 on SAR Gog having a gain of approximately 95 db. The outout load of this aiplificer ia” i speed 40 Ohm Relay (...
