[GreenKeys] The things I worry about.

[Jeffrey D Angus]

Running RTTY.
Assuming 170 Hz shift, and 2125 Hz mark tone.
What frequency do you tell people you're at?
If your receiver is in lower sideband mode and your marking frequency is
7097.875 KHz, do you tell people you're transmitting on 7100 KHz. That
would be where the suppressed carrier isn't if you're running SSB AFSK.
Do you tell them you're transmitting at 7097.875 KHz because that's
where the mark tone is. Or do you tell them you're at 7097.790 KHz
because that's the mid point between your mark and space frequencies,
especially if you're running true FSK and there isn't a suppressed carrier?

What do you tell them if you're using an AEA PK-232 and you're too lazy
to change the default RTTY shift from 200 to 170 Hz?
Which tone is 30 Hz off frequency, or are both tones 15 Hz off frequency.
