And Hook up the LM386 to RX 12V line. This way it will be off while transmitting.
Hook up the SSM2167 board to TX 12V line. This way it will be off while receiving.

>I installed an SSM2167 pre-amp processor on my V3 uBitx. I am getting microphone audio into the speaker. It only appears from about 1/2 to 7/8 of the volume pot range. Verified with my scope. It does not go out over the air, verified by QSOs. Reducing the mic gain reduces the leakage, but does not eliminate it (also as seen on the scope). More of an annoyance than anything, but it would be nice to get rid of it, because it is in the "sweet spot" for listening.
