Shilling, Eric . 1999. Helmet Headsets for ATVs. 9957 1301. San Dimas, CA: U.S. Department of Agriculture, Forest Service, San Dimas Technology and Development Center. 3 p.
Use of the standard Forest Service Bendix/King radios, while wearing a motorcycle helmet, requires the use of a helmet headset. A number of helmet headsets are available from motorcycle accessory suppliers, but none are designed specifically to be used with the Bendix/King EPH series VHF radios that Forest Service employees use. San Dimas Technology and Development Center (SDTDC) has built a prototype adapter that can solve the problem. The adapter was made from parts available from Bendix/King and the local Radio Shack or electronics supply house.
