Re: Easi link for audio connection - BITX40 and Digital mode

Pin 3 of the LM386 will vary in amplitude with where you set the existing volume control.
You may want to instead take audio from pin 1 at the top of the the existing volume pot, 
perhaps have a second independent 10k volume pot for your digital mode audio.

You can take audio from pin 3 on the LM386 chip, and ground anywhere. That'll get you unamplified audio signal for digital mode. Works fine :)
