[Elecraft] MFJ 434B Connections

[pastormg2 at verizon.net]

Hi, this is Mark Griffin, KB3Z. Has anyone connected a MFJ 434B Voice Keyer to the K3? I assume that I would connect my Heil HM-12 microphone to the external microphone jack on the front of the unit. The man from MFJ said I would have to set up the jumpers in the unit for a Kenwood. But for some oddball reason they use a modular cable plug to connect the 434B to my K3. I realize I would have to use the MIC Connector on the back of my K3 and would have to make the necessary change with the K3 so it knows that I am using the MIC connector in the back. But where do I find one of these Modular cables to connect the 434B to the K3. Any help or advice would be very much appreciated. Mark Griffin KB3Z
