Am using a Super Combo Keyer II by ZS4TX where the audio out from that
box has pins 1 and 6 connected to the output of a 600 ohm 1:1
transformer with pin 1 being decoupled with a 10 microfarad
non-polarized audio capacitor. This looks like pin 1 then is the audio
source and pin 6 is a floating audio ground.
The question is do I use this pin 6 as my ground for pin 7 or 8 for the
K3 mike connector or would any old ground work for pin 7 and/or 8 for
the Elecraft?
Thanks,
Lew W7EW/W7AT
