Rearange

I'm right handed so I rearanged the radio and interface boards around to make it more comfortable to play with.  Now I really need a knob 'cause spinning the encoder shaft is tedious...

No button debouncing was terrible so I whipped up a basic timer comparison test and now band selecting actually works.

Right above the Si5351 board from Adafruit are two potentiometers currently wired to the SSB6.1 labeled as WB/BW and WP/PW on the schematic.  I believe WB/BW is for the receiver band width control and adjusting it does seem to change the audio response.  I think the WP/PW pot controls the mic gain.  Above the two pots are three digital potentiometers I got from SparkFun I want to use instead of the analog pots.  I'd like to be able to use the remote UI to control the radio volume, rx band width, and mic gain and digital pots should do the trick.
