No WSPR modulation on transmitted signal

I can't figure this out...

WSPR was working fine with my Vista computer, a SiglanLink USB, and a Yaesu FT-857D, getting lots of spots. Then a few days ago I stopped getting spots on any band... zero!

So i dug out my old Kenwood TS-520, stuck a short wire in the antenna socket, and listened to my signal... and it's just a non-varying signal (unlike everyone else's signal with the modulating warble). WSPR transmits on schedule on the two-minute mark, and on the right frequency that I specify... just no modulation.

Any ideas?
