[Elecraft] KX3 Mic input problem

[Phil & Debbie Salas]

Here in the US we can order a Mouser 171-7435-EX 4-conductor 3.5mm plug.  Plenty in stock (over 2500).  Cost is around $2.50 each plus shipping.

“The KX3 mic input uses a multi barrel jack plug which enables up & downchannel changing using buttons on the hand mic. I an regular stereo jack isplaced into the socket, the radios VFO start to change continuously. To usedigital modes, I need to use the mic input to connect to my sound card.There appears to be a setting on the Configuration menu to turn off theup/down and PTT but this is non functional. When selected on the menu byVFOB the options on VFO A say n/a.So the question is - how do I provide an input to the Mic socket on the KX3without having this problem?Does anyone know of a solution to this issue. “
