Kevin,

I've only used two outboard dsp units.  The first was the W9GR, which was a 
kit.  I bought it from a station on the 40-meter swap-net, about 10 years 
ago.  It works very well, both for ssb and cw.  However it has severall 
controls and is tricky to run.  A little practice aleviates most of that 
problem, though.

The second dsp I have used, and still use, is the Clear-Speech, now sold by 
Hile, (if they still do).  I have the little box without the speaker, 
because the original one without speaker didn't have a headphone jack.  I 
think the Hile units have the jack.

The Clear speech does a great job for both ssb and cw and is fully 
automatic.  I have heard almost nothing about the Hile units.  I suspect, 
because most transceivers have built in dsp, now.

I have only used one built-in dsp--the one in the IC-718.  You might 
remember that one.  I have never been impressed with the performance of that 
one, so I use the Clear-Speech, instead.

Sorry, I can't help more.  Good luck.

73,
Gale
