David,
I have a Kenwood TS-2000 and used the SignaLink at first and still use it for
modes other then RTTY. On the TS-2000 you need to run FSK to take advantage of
the built in filters. A friend made me a custom interface from parts he already
had and I've been running FSK ever since. The filters make all the difference
in the world in contest when signals are on top of each other.

The laptop is a Gateway running XP, N1MM, into a SignaLink USB outboard sound
card, into the ACC port on the TS-450s. I am neither for or against true FSK,
just the SignaLink allows me to do many other types of "sound card" digital
modes such as PSK and Olivia.
I was able to do RTTY no problem with the system before the 400hz filters
