I want to add the digital modes to my uBitx. Before I reinvent the wheel, I would like to know how to go about connecting the audio in an output to the uBitx. Do I put a relay or multi-pole switch can I do something about keeping the audio levels consistent when switching from Voice to digital communications?
Are there points on the board where I can directly tap the " into?
I use the KISS principle. When I want to do SSB phone I plug in my microphone. When I want to do soundcard digital I unplug my microphone and plug in my computer. It's too simple and extremely reliable:)

I used your method with great success. I did however, substitute R3 with a 1k pot connecting the wiper to C1. I wanted to be able to use an amplifier on digital but not at full uBitx power. This works to allow me to go from 0 to max out on the amp.
