Jimmie:

Just having a bit of fun. I am only familiar with "space modulation"
when it comes to modems, as much data is contained in the key off mode,
and the length of time key off occurs, as in the key on condition and
its length of time (at least in one method of data transfer I am
familiar with.)

Whether there is any relationship of one to the other is a mystery to
me--like I said, just poking a bit of fun.
