Default bandspread tuning tutorial?

Just for the hell of it, and to give this DX-160 one more chance, can anyone
point me at a bandspread tuning tutorial? Is bandspread tuning similar in
concept to a vernier by any chance? And, why is it necessary on the DX-160
to use the main tuning to the specific "white crosses" on the dial to use
the bandspread tuning dial?


Find a station at either end of the band of interest. Set the
bandspreda to 0 or 100 as required. Fine tune with the Main tuning.
Make this station your bandspread anchor. Using a frequency guide
write down known stations and their bandspread indications without
moving the main tuning. Do a chart for every band. Your $50 radio
will then be perfectly calibrated for SWL.

For example 12095 would be your anchor at the top of the 12 MHz band.
As you tune down on the bandspread you'll across some powerhouses.
Note their actual frequency and their bandspread indication on your
chart. Soon you'll be able to guestimate the gaps.
