No, it does NOT. The frequency shifting can all be done with audio if
WSJT-X is set up for no CAT control!
At the risk of transmitting harmonics as well as the principle audio...
Plus not all sound card responses are 'flat' so the levels, if outside
the tested range (say 1500 Hz +/- 500 Hz) vary much, it may be too loud
(overdriving) or soft.
A simple test, into a dummy load, set your audio tone for a lower tone,
watch the output, repeat with a mid-range tone and a higher pitched
tone. If you don't have to readjust the audio drive to the radio (while
keeping NO ALC), you're fine. If you do have change levels, use the
frequency shifting of WSJT-X to stay within the same range.
Sometimes cheap audio, is REALLY cheap audio.
