well, pretty much everything after the 735 uses DSP in the radio somewhere.
The 735 might even use DSP to some extent, though I don't think it does.
DSP, digital signal processing, can be anything from a small chip that 
controls the display, to advanced functions to do with IF stages and 
filtering etc.
