I bought in the late 90's. It does not require bias, although using bias will not harm it. HEIL has a resistor in the mic to protect it from bias. The mic has an eight pin adapter for the Kenwood rigs, but I don't use it. you can just remove it and plug the mono mic plug into the mono mike jack in the back of the K3. You can also plug the phones into the rear panel using an adapter to reduce the size of the stereo plug. If you remove the cable adapter you will have use a foot switch for PTT when you don't want to use VOX. It works great. Thank you Elecraft for letting me keep my old headset mic :O) 73, Tom, N5GE - SWOT 3537 - Grid EM12jq "Those who would give up Essential Liberty to purchase a little Temporary Safety deserve neither Liberty nor Safety" An excerpt from a letter written in 1755 from the Assembly to the Governor of Pennsylvania.
