[1000mp] MarkV AF output for digital modes

[Dave, AA6YQ]

I'm using pin 2 of the MarkV's RTTY jack to drive both soundcard and
PK232 inputs. During pileups, I'd like these inputs to see both main and
sub-receiver audio. Page 15 of the MarkV manual asserts that one can
choose one or the other, but not both. Is there a way around this? If
not, I assume that one must use the AF Out jack, which provides both
main and sub-receiver audio on separate channels; can I simply connect
the two channels together, or is a summing network required?
