I have found in a closet at work a Motorola Transmitting device about the size of a bearcat 245xlt handheld scanner. with a flesh colored microphone with a push button on the mic. Sotra like an old SS undercover mike. I opened the gadget up and its aged on the inside but stamped in it is F1 169.025 and F2 168.975, It used batteries looking like A oir F cells to power it. the antenna appears to be either the metal back where the belt clip is or the braid of the mic cable. Its the same type of plastiuc molding that a HT200 was made on in the 1960s. I suspect its a undercover transmitter of some sort... Any one has any more ideas on who used this......
