[RTTY] RTTY is getting lower and lower in frequency on 20

[Inbody, Donald S]

Excellent observation.  Learning the full capability of your equipment and how to communicate under difficult circumstances is the mark of a good operator.  If "arm chair" copy is the only thing one can do, then that operator is not working at the edge of the envelope.

If the CW signal is not much louder and don't have a lot of  
keyclicks, you can usually copy an RTTY signal through an adjacent CW  
QRM even when it touches one of the FSK tones.

Unless there are two separate CW QRM signals riding *both* of the FSK  
tones, you can copy RTTY that is strong enough by using Mark-Only or  
Space-Only copy.

Mark-only and Space-only also works well with two RTTY stations that  
are overlapping each other, as long as one of them is not overly  
strong as to get their keying sidebands to interfere with the "clear"  
tone of the RTTY signal that you are trying to pick up.
