Right, and I've long promoted that concept.  BUT -- I've recently been 
comparing several (five so far) outboard A/D converters, four models 
that connect to the computer via USB, on that uses Firewire, and I've 
found that all of them result in noticeably more reliable decoding of 
RTTY and JT65 signals, especially weaker signals.

I use MMTTY with N1MM for RTTY contesting, and MMTTY with DXKeeper for 
general operating.  I use AFSK and VOX.  As K6DGW has observed, as long 
as you take reasonable care to get levels right, it's just as clean and 
reliable as FSK, and the hook up is really simple.
