OK, but as long as there are no other restrictions on the channels it
should be no problem, something like a saw on one side (to detect speed
and corresponding carrier wave speed), and an AM modulated timecode signal
on the other.

Use the say to calculate the carrier wave for the 2nd channel, then decode
the timecode.
