Only One Available. This is an original German WWII \u003cb\u003eKehlkopfmikrofon b (Kmf.b)\u003c\/b\u003e throat microphone of the type used with Wehrmacht armored-vehicle and radio communication equipment. The assembly has the characteristic dual throat pickups mounted at the ends of a flexible, leather-covered neck band, allowing the two microphone elements to rest against the sides of the wearer's larynx. The microphone housings are black molded composition\/Bakelite with circular contact pads, while flexible metal-sheathed leads connect the components to the control assembly.\u003c\/p\u003e\n\u003cp\u003eOne microphone housing retains a white Wehrmacht acceptance marking consisting of the national eagle above \u003cb\u003eWaA 690\u003c\/b\u003e. The associated black molded switch housing has a spring clip for attachment to the wearer's clothing and is clearly molded:\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cb\u003e(Fu)b\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe switch incorporates the operating control used to place the microphone circuit into transmission.

The leather covering of the neck band is heavily worn, dry, and locally deteriorated, while the black housings have scratches, abrasions, and finish wear. The white acceptance marking remains readily identifiable and the \u003cb\u003e(Fu)b\u003c\/b\u003e marking is sharply defined. The cloth-covered cord shows age, discoloration, and storage wear.

Tank crews worked in confined compartments surrounded by considerable mechanical noise from engines, transmissions, and moving tracks. During combat, the additional noise of weapons fire and impacts made verbal communication particularly difficult. The German military therefore employed specialized communications equipment that allowed crew members to exchange orders and information while operating under these conditions.\u003c\/p\u003e\n\u003cp\u003eThe Kehlkopfmikrofon, or throat microphone, addressed this problem by detecting vibrations produced directly by the speaker's larynx. This method substantially reduced interference from surrounding noise and allowed speech to be transmitted more clearly within the vehicle. German forces employed several versions of the equipment, including the Kmf.a and Kmf.b, which were incorporated into different radio and intercom arrangements.\u003c\/p\u003e\n\u003cp\u003eWithin armored vehicles, the throat microphone formed part of a broader communications system known as the Bordsprechanlage, or onboard intercom. Crew members wore headphones connected to the vehicle's electrical communications equipment, allowing the commander to issue instructions to the driver and other crew positions. Depending on the installation, the system also provided access to the vehicle's radio equipment for communication with other tanks and command elements.\u003c\/p\u003e\n\u003cp\u003eThe development of reliable crew communications was particularly important to German armored tactics, which emphasized coordinated movement and rapid responses to changing battlefield conditions. Radio-equipped command vehicles could relay instructions across dispersed formations, while internal intercom systems allowed individual crews to carry out those orders efficiently. This arrangement was especially valuable when maneuvering through difficult terrain, maintaining formation, identifying enemy positions, or coordinating movement with supporting units.\u003c\/p\u003e\n\u003cp\u003eThe Kmf.b was particularly associated with the communications equipment used by Panzer crews, although its application extended to other military radio installations. German armored vehicles employed several types of radio equipment throughout the war, including the FuG series of transmitters and receivers. These installations varied according to the vehicle's intended role, with command tanks generally requiring more extensive communications capabilities.\u003c\/p\u003e\n\u003cp\u003eAs the war progressed, German armored formations continued to depend heavily on radio communication, even as their vehicles, equipment, and organizational structures underwent substantial changes. The ability to maintain contact between individual crew stations and communicate with other vehicles remained essential to the operation of tanks, assault guns, and other armored fighting vehicles throughout the conflict.\u003c\/p\u003e","brand":"Original Items","offers":[{"title":"Default Title","offer_id":46025943482437,"sku":"ONFV2026037","price":450.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1524\/1342\/files\/FDD73DC9-1B10-4EA0-89E9-E20D4703E99F.jpg?v=1792179526","url":"https:\/\/www.ima-usa.com\/products\/original-german-wwii-wehrmacht-kmf-b-panzer-throat-microphone-with-fub-chest-switch-and-connecting-cord","provider":"International Military Antiques","version":"1.0","type":"link"}
