Nick et al,

I recorded about 15 minutes of close to three of their loops and there was 
no dead air. There was continuous sound effects, voice IDs and regular speed 
CW IDs (sounded like about 1 KHz tone), which leads me to believe that they 
did not intersperse any slow code.

But my point was: If I were going to test traditional modulation with 
something exotic like slow code (true QRSS or otherwise), then I would not 
bury it within the regular data, but segment it in some way so that the 
recipient would know to alter his receiving technique.
