I am working on a new board that will give a few extra features to stock uBitx.
Its an Audio board providing easy access to Audio I/O pins. (add in your own AGC board, External amplifier...)
A place for an SSM2167 Mic Pre-amp. (with filtering for feedback and shutdown on TX)
Simple 4 component PTT POP fix. (BS170)
Switchable 200hz CW filter. (LM324)
and a bonus Snap off section with a 3.5MHZ BCI filter for the RX chain.
Here is a pre-view, NOTE this is a WORK-IN-PROGRESS.
Suggestions and corrections welcome.
