Wrong.? ? ?This part that? reads
? ? <<? ?second LO always at 45-12mhz
should say
? ?second LO is at 45-12=33mhz for LSB? and? 45+12=57mhz for USB
Leaving the second LO parked at 57mhz will likely give fewer birdies.

Currently the uBitx BFO is always below the crystal filter to avoid the tones, second LO always at 45-12mhz
Would be nice to? be able to switch sidebands by flipping the BFO to high or low side.
Could then have the second LO at either 45+12 or 45-12mhz, whichever gives fewer birdies
and other such artifacts.?
