Figure 4-18 Control Board Schematic (81596) on page 4-31 and the third
paragraph in the narrative description of that board on page 4-29,

To paraphrase what the manual says, the TX OUT is pulled to ground by
Q11, which is a MPS 6514, when the Omni VI wants to transmit. If the QSK
circuit in your amplifier will pull the TX EN line to ground when it is
ready for drive, the Omni will oblige.
