[Elecraft] KX3 hookup to HF Packer Amp

[Walter Underwood]

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.”
