If you are operating AFSK, or have a low end rig that does not do FSK RTTY, then you would need to calculate the numbers as you suggest. Most rigs that are set up for FSK RTTY will read out on the RTTY Mark Frequency, but some will read out on Space, so it does vary between rig designs. Since the tones are usually operated at narrow shift, the most you can be off is 170 Hz:)
I never had a rig that could do FSK RTTY used to have to get a calculator out to figure out the right dial frequency if I wanted to link in to certain autostart bbs's. I still have my Kenwood TS440SAT and even though it has a button for FSK, it really can only do AFSK. As an aside, this rig still works and since my wife recently upgraded to General, by her request, I set up the rig for listening with a multiband trap antenna. She plans to use this initially when we figure out how to get power from the battery through the firewall in her truck. We just got the bug catcher antenna so she can try out HF mobile, mostly on 75 meters. 73, Rick, KV9U John Becker wrote: > I have no waterfall when I operate RTTY or software > or computer or can click on anything.
