When you transmit a shortwave signal from an earth-bound transmitter, it

If you were to transmit such a signal from space, it would bounce in
pretty much the same way -- except that instead of bouncing down to a
listener on Earth, it would bounce back out into space. Not
particularly useful.

Nonsense (at least above the MUF). Consider QSOs made using Mode K (21
MHz uplink, 29 MHz downlink) of the RS-10/11 and RS-12/13 ham satellites.

I recall listening to a satellite launched by China that played 'The East is
Red' as it came within range. Don't recall the frequency right off hand but
think it was up near 20 MHz or so. Perhaps someone else remembers it.

I did a quick Google and did find that that particular satellite was launched on
April 24, 1970 and used 20.009 Mhz to broadcast 'The East is Red'.

CHINA-1 and CHINA-2 seem to fit your description:

I'll have to get a sound-card going again here as it would be a thrill to listen
to the recording they have up there on the site.

Almost as much of a thrill as it was to hear it live at the time I'll bet.
