Small correction: for the FT-990 and the original FT-1000MP, VOX cannot be activated in PKT mode (AFSK) .

I myself use (FT-1000MP) the "1600/1800" Packet tone pair in Menu 6-5.  This gives me a relatively flat waterfall when I select the 2.4 kHz IF filter (Inrad).  

Set the Packet offset (Menu 6-4) to Minus 1615.   Your VFO dial will then show the Mark frequency of the transmitter, since PKT mode of the FT-1000MP works in LSB.

If you prefer to use narrow filters, centering an RTTY signal to this tone pair will place your Mark tone at 1615 Hz.  Be sure to select 1615 Hz/1785 Hz as the tone pair in your software modem.  All filters will be centered at 1700 Hz.
