You want to set it to the center of the two tones you are using for AFSK. If 1000Hz is your Mark frequency, and 170Hz is your shift, then you should center at 1000-(170/2) or 915Hz.
You can do this graphically with Spectrogram using the techniques detailed on the Elecraft Builders Resources pages. Set the cursors based on the AFSK tones from your RTTY modulator software or hardware. Then center the filter peak between the two cursors. hope this helps! - jeff wk6i At 10:43 AM 10/9/2005, Charlie, W0YG wrote: >Since the ability to set filters when using the RTTY mode is different than >LSB/USB if used for AFSK, what center frequency do you use?
