Jim, The KX3's mic jack has some special wiring to work with the MH3. As alternative, you can use the ACC2 jack (2.5 mm) to wire in a PTT switch. This is discussed in the KX3 owner's manual -- see the ACC2 IO menu entry. This would allow you to use the mic jack with your headset/mic.
Also note that the "XMIT" switch functions exactly like PTT, and is conveniently located close to the mic jack. 73, Wayne N6KR On Nov 12, 2014, at 6:15 PM, James Bennett <w6...@me.com> wrote: > Need a little help on this one.
