Chris,
The CAL S LO and CAL S HI values are as you observed.
Turn the RF Gain to full clockwise, and remove the antenna. Turn the
preamp on. Adjust CAL S LO first so there are no bargraph LEDs illuminated.
Then tune in an S-9 signal (preamp on or off, your choice), and adjust
cal S HI for

good S/N.
Is there an adjustment or
