[RTTY] Mark & Space - High Tones

[Robert Chudek - K0RC]

As Joe says, the space RF frequency is always (should always be) the 
lower of the two RF frequencies being transmitted. When it is not, 
people cannot copy you unless they invert their decoder.

So the graphic should look like this:

Space    Mark    Carrier    Space   Mark

So... what's a crutch to help you remember this? Here's one visual "When 
you step off into space, you are going to fall down (lower)."
