Let's start at 20:30, Sunday evening:

Mode:
* RTTY, 5 bit Baudot code, 45.45 baud
* 850 Hz shift
* Mark low (this is opposite of normal ham band convention)

Actual transmitted frequencies:
* Mark  7088.575 kHz (+/- QRM in 1 kHz steps)
* Space 7089.425 kHz

Tune a PRC-47 or GRC-106 as follows:
* Indicated freq 7087 kHz. USB, of course.
* Mark tone  1575 Hz (this is fixed and non-adjustable)
* Space tone 2425 Hz (same here)
* Centered around 2000 Hz (yup, this is, too)

For a modern SSB rig with a sound card modem, this setup might work better:
* Indicated freq 7087.5 kHz USB
* Mark tone  1075 Hz
* Space tone 1925 Hz
* Centered around 1500 Hz

A true FSK rig like a GRC-46, GRC-26, etc. would tune to 7088.575 kHz (LOL! 
Just zero-beat one of the SSB-based rigs on the net!).
