View of modified ATS-3 CW/RTTY rig

Below is a screenshot of JE3HHT's Windows RTTY app, 'MMTTY', captured by 'Easyscreen', after an actual ATS-3 RTTY QSO. Also shown is my new Windows app, 'DDS_RTTY for the ATS-3', which runs concurrently with MMTTY.

The image below represents the current state of the 'DDS_RTTY for the ATS-3' hardware interface schematic.
