Hello List,

Excuse me if this has been discussed before, but I am new to Icom 
radios.  For years and years I've owned Kenwood radios, but recently 
purchased an Icom 756 Pro (not II) Repack.  It is a 4000+ serial number, so 
I'm guessing it's late model.  (Can anybody provide a manufacture date)

My question.  To me, some of the audio sounds "raspy" or "fuzzy".  I 
realize this is a DSP rig where my TS850 is analog.  However, I've seen 
lots of rave reviews about the audio in the 'Pro.  Is this fuzziness 
normal?  It is especially noticeable on CW signals with the 500 & 250 hz 
filter in.  And some signals tend to have more "fuzz" than others.  This 
could also be entirely user error as there are so many settings on the 
Pro.  One thing I have noticed is that using the NR fuction tends to 
"smooth" out the fuzziness, although not completely eliminate it.

I found it interesting that Icom themselves point out the old "vinyl vs CD" 
argument.  They actually say in the document that if you're a "vinyl" 
person, perhaps a DSP radio is not for you.  I wouldn't consider myself a 
"vinyl" person by any means, but the "fuzzy" audio really bugs 
me.  Personally, I think the audio in my old Kenwood is superior to what 
I'm getting from the Pro.

Any suggestions would be great.  I've been playing with the rig for the 
past couple of days and I'm luke warm as to whether or not I like this radio.

Thanks,
