A monaural (two-conductor) 3.5 mm mic plug will work with the KX3. That's how the ProSet is used with it.
One disables the PTT function (otherwise plugging in the mono plug will put the KX3 in xmit). You can use VOX or tap the XMIT switch on the KX3 to switch between tx and rx. Ron AC7AC -----Original Message----- Actually it does not matter. No adapter is included with the K3 or KX3. The KX3 will include a mic plug you can wire yourself. It is a 3.5mm 4 conductor plug. There is a menu item to enable or disable the up/dn button signals provided by the MH3 mic. I connected a standard 3 conductor audio cable that breaks down to two RCA connectors and use that to interface my CM500 and a PTT switch. 73 Greg AB7R On 2/19/2012 11:15 AM, [email protected] wrote: > Alright. > > I have a question about the CM500 and PTT > > If I want to use PTT is an adapter already included with the package or do I need to by it.
