You want the ACC2 jack. From page 5 of the KX3 manual:
"Keyline Out and GPIO (ACC2) The 2.5-mm stereo ACC2 jack provides a keyline output (ring contact) and a general-purpose 3-volt logic signal (tip contact). The keyline output goes low during transmit, and can be used for transmit/receive switching of linear amplifiers and transverters. For keyline voltage and current limits, see Specifications.” wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Jan 4, 2019, at 6:11 PM, Rick McGaver via Elecraft > <elecraft@mailman.qth.net> wrote: > > A friend has a KX3 and want to use a HF Packer Amp.
