"I used Spectrum Lab to examine my TS-590S TX monitor audio for WSJT-X versions 
1.9.1, 2.00, 2.2.1, and 2.3.0.   All versions exhibit audio harmonics but each 
is about 40dB below the wanted modulation."

Same test, same results, with 2.4.0-rc1.  All tests with FT8.  Was the reported 
problem with a different mode?

I used Spectrum Lab to examine my TS-590S TX monitor audio for WSJT-X versions 
1.9.1, 2.00, 2.2.1, and 2.3.0.   All versions exhibit audio harmonics but each 
is about 40dB below the wanted modulation.

There is a very noticeable difference in the primary modulation signal between 
WSJT-X versions.  1.9.1 and 2.0.0 show wide modulation with characteristics 
similar to key clicks at each tone change.  Versions 2.2.1 and 2.3.0 show a 
softer change between tones with no "clicks".
