If you must have a log amp, I'd make pads for an optional AD8310 (the improved and cheaper AD8307) ?on the main board and have it drive a Nano analog input. ?Make a dandy S meter when not being used to troubleshoot the Bitx or perhaps other gear. ?Those that want it could go out and buy one, or you could make the extra part a buying option at hfsigs.
Of course, we'll quickly run out of Nano pins. ?I still like the idea of the Si5351 on the main board, a connector off to the microcrontroller/display of our choice. ?I'd go Teensy 3.2, likely never run out of pins or anything else (mips, flash, ram, ADC bits, serial ports, ...).
