[RTTY] getting back on ritty

[JIm]

Hi all
I am just getting back on RITTY after being off the air for the last 5 
years. Looks like a lot has changed with most every one running sound 
cards. I am on with a old pk232mbx  and I spent $$$$ for pkTerm (lots of 
bugs) . The rig is a ts950s I would like to run FSK. So what's the best 
way to go using a sound card (software, interface, or what every)

Thanks all
Jim
