John,

Have you reversed the mark and space tones by any chance?   RTTY requires that the mark 
and space frequencies have the proper relationship or all you get is gibberish.

I think I recall that you are using fldigi.  fldigi workes backward from most RTTY 
demodulators in that the standard is lower sideband.  fldigi uses upper sideband as default.

A quick way to see if tone/sideband reversal is the culprit is to toggle the "Rev" (reverse) 
button on the fldigi screen just to the left of the "T/R" button (lower right corner).

IIRC, fldigi wants the radio to be set to USB and the "Rev" button not illuminated.

If you don't even get gibberish, perhaps the squelch is set too high.  Those controls are also 
on the lower right corner of fldigi screen.

Good luck.

73,
