If the headset has a dynamic mic element, it won't need any voltage. Heil and others have plenty of these, but you need to know what you are getting. PC type headsets that have a condenser mic element need the voltage, either provided at the mic jack or added externally. I have a Yamaha CM 500 which a number of hams use. It comes with a small battery box for 2 triple A batteries. It plugs inline in the mic cable to add the voltage if not provided elsewhere. 73, Steve KW3A On 8/18/2013 9:37 AM, Butch Bussen wrote: > Yep, very good points, and a couple more thoughtss.
