That was my original thought, the FT-817 is as wide open as the 
proverbial
barn door without extra filters.  The TS-2000's IF DSP will help a lot 
to get
rid of the "hiss" evident in Jon's recording.  I still have a DSP-599zx 
though,
since its random noise reduction mode works a lot better than the NR1 
mode on
the TS-2000 which needs a fairly good SNR to work with.
