Rather depends what you mean by "military" - most (old) UK military headsets that I've seen (typically used by ATC) have carbon-granule microphones, like old telephone handsets, so you'd need some sort of amplifier to use with a "normal" audio input. They work by the carbon varying its resistance as sound waves compress and release it, so you need to pass a voltage through to "read" the resistance. That's the limit of my knowledge, I'm afraid, so I can't help further than that - sorry! Howard Winter St.Albans, England -- http://www.piclist.com hint: The PICList is archived three different ways.
