Jon, the TS-930S does not have the FSK on the 13 pin connector, instead it uses the RCA Jack for FSK RTTY.

In addition, the TS-930S sends FSK up-side-down.  So you need to check the type of interface you get to make sure you can reverse the output with reversing the receive.

A very good article on explaining this is at:

http://www.w5bbr.com/pttfsk.html

and I have used this exact circuit on my TS-850S.  Pay close attention to the words where the author tell how his TS-940S was sending FSK upsidedown and how he reversed the leads on the transistor.

is a website for the Rascal Interface for FSK/RTTY and PSK. You might want to look at it.

Hope this helps
