I said earlier:
"If I set the tone to 1500 Hz, the FT8 mid-band target, I'm presented with the
cyclic ALC and some ~193 Hz, -50 dBc sidebands. "
Ten KHz/div is too coarse to see these. Try again.

Here are some spectrum photos from the tune signals of both FLDIGI and WSJT-X
1.8. All three are essentially identical showing some low level sideband
noise +/- 30 kHz and down > 60dBc. There's no apparent difference in the
spectra between pumping and non-pumping ALC, as Wes reported.
