Yes, you need to set SHIFT such that the MMTTY FFT display is
symmetrical about the mark and space frequencies (the vertical
yellow lines on the FFT display). Set WIDTH as low as possible
without attenuating the mark and space frequencies. Set K3 shift
control to fine granularity (config/pb ctrl/shift=.01)
In MMTTY, turn off NET, AFC, ATC. Make sure MMTTY MARK frequency
matches K3 PITCH.
