Hi Tom,

First, thanks for the QSO on the 160 meter contest last weekend.

Integrating RTTY capability into your station can be broken down into high 
level steps of Receiving RTTY, Transmitting RTTY and Integrating RTTY into 
your favorite contesting program.

1.  Receiving RTTY - Most folks use a PC and most PC folks use MMTTY (its 
free).   Download and install it.  You need to make up a cable to connect 
the receive audio from the radio to your sound card.   Most radios have a 
connector on the back that supplies receive audio that is independent of the 
volume control on the radio.   Make a cable up and test with MMTTY.  You 
should be able to receive and decode RTTY signals using MMTTY.  See MMTTY 
docs for more details.

2. Transmitting RTTY - The FSK method is recommended.  You need a serial 
port and you need to wire up two keying transistors off the serial port to 
do the PTT on the radio and the FSK on the radio.   There are several 
circuits on the web but this one is very robust:

parts, I can send them to you as I have many spares to help get folks going 
on RTTY.     After the keying transistors are wired you need to setup MMTTY 
to use FSK.  See MMTTY docs.  After this is running you should be able to 
make contacts using the MMTTY application.

3. Integrating RTTY into your favorite contesting program.  If you use N1MM 
you do that on the Config>ConfigPorts menu.  See N1MM docs for more details.

Ask if you have any issues or need help.
