Andy, The main advantage with FSK is that you have the ability (with some rigs) to use certain filtering specific to RTTY. My ICOM rig has superior filters that are double humped and shaped for the 170 tones. I can not use them on AFSK, but due to the requirement of needing another COM port and another interface for FSK switching, I have never set it up due to the ease of just using AFSK. I also rarely use RTTY and consider it obsolete for my purposes since it is mostly used for contesting these days.
With FSK, there is no setting up of the drive levels from the sound card since you are basically switching the frequencies from inside the rig. 73, Rick, KV9U Andrew O'Brien wrote: >OK, my cable for my Microkeyer should arrive in a day or so My new >rig provides for FSK RTTY as opposed to the AFSK my old rig has been >providing for the past 18 years.
