TELEPHONE "BUG" DETECTOR
SCHEMATIC
If your telephone has “bugs” this circuit may help you “kill” them. It will warn you if somebody is eaves dropping on your telephone line by means of some device connected on your line. The circuit draws its power from the telephone line and can be left on the telephone line continuously, without fear of hampering the normal use of the telephone. PCB 30x40mm
