I can't hear it here, but your description sounds a lot like JT65 ... 
a mode used a lot for EME.

 Hello,
 
 Around 17.075 MHz I've heard a mode I can't identify. It appears to
 have an 8 tone coding scheme and is about 150 Hz wide. By ear there
 are around two tones per second. The decoders provided by Ham Tadio
 Deluxe are ineffective.
 
 What am I hearing?
 
 Thanks,

Oh sorry, forgot to mention it could also be PROPNET signals ...

Hello Ed,

Most likely JT65A as activity on 20 meters is generally centered
around 14.076. This mode is part of WSJT's suite of modes. It excels
at weak signal work using very brief message formats and 60 second
xmit/rx sequences. 

See http://physics.princeton.edu/pulsar/K1JT/ for details.
