On-Off Switch on Volume Control will not turn on.
#parts
I used a separate power switch, that way I can use a normal volume pot with 1/4 inch shaft if I wish. Also means that if pot gets noisy, I only have to replace with another audio pot. AL VE3RRD

Bitx40 v3
I haven't changed the firmware in my uBITX yet, but from what I gather, if you are loading a sketch consisting of a single .ino file then it should be similar. But if you are using multiple .ino files

Protection of Q90
Both Q13 in the Bitx40 and Q90 in the uBitx are the first stage in the transmit chain. Both have the "issue" of remaining connected to the antenna port when the transceiver is in receive mode. In both

ubitx AGC?
Have others tried the original uBitx audio AGC circuit? Looks like it would be simple to add on a small perf board with selectable FAST/SLOW front panel switch using different values for C70 / R71. AL
