Not true.  One should use DATA A which transmits as USB but disables the
compression and TX EQ.

DATA A is correct for FT8/JT65/JT9 as well as PSK31/PSK63/PSK125 and any
other audio (subcarrier) based data modes.

AFSK A is the correct mode for AFSK based RTTY as it transmits LSB and
includes an audio filter centered on the mark/space tones to clean up
any hum/noise/clipping/etc. from the sound card or due to over driving
the audio input.

The secret to using DATA A and AFSK A is to connect the sound card to
the "LINE IN".  Select DATA mode and then use MENU:MIC SEL = LINE IN.
Once you have selected LINE IN (*NOT BEFORE*) adjust MIC GAIN for
four bars of "ALC" with the fifth bar flickering.  You *CAN NOT* set
mic gain in SSB or with MENU:MIC+LIN=ON because the mic gain will
adjust the mic input (front or back) and not the LINE input.
