Re: Simples questions.


Hi Gerard,

The mic, phone, and CW jacks are all for stereo 3.5mm plugs.  The mic jack uses the tip connection for audio, the ring for PTT, and the shield for ground.  The phone jack wires the tip and ring both for audio, so a stereo headset must be used (or a mono set wired for a stereo plug).  The CW jack is stereo so that a paddle may be used if desired.

I don't recognize the schematic, what rig is that?  The AGC will depend on if you want IF or AF AGC.
