Yes, the AFSK A data submode is optimized for RTTY operation. The default sideband is LSB and the use of the dual filter is possible. Furthermore, the K3 dial display shows the mark frequency. If you are using an RTTY mode with an application such as MMTTY, you will find the AFSK A mode useful and tuning will be done using the K3 VFO.
Yes, AFSK A is the way to go, and it works very well with VOX! Note also that in the last year or two, "authorities" say the dual passband and narrow filters are a bad idea, and recommend 400 Hz bandwidth IF. The problem with dual passband and narrow filters is phase shift, which degrades decoding. Many top RTTY contesters have taken that advice.
