I'm getting ready to try some RTTY operation. I have an Icom IC-718, a Rascal sound card interface I use for PSK31, and have downloaded but not installed the MMTTY program. I also have a registered copy of MixW. If anyone is using a similar configuration or could share the pros and cons of using AFSK vs the rig's FSK mode I'd appreciate it. 73, Tim, N9PUZ
