I believe you adjust the lower 1-5 coils to the station you want that's in the range of that particular coil, and use the trimmer on the top of that coil to fine adjust the station. Or it could be the other way around.

If the stations are strong enough you can tune the coils/trimmers without to much trouble, but if there is a weak station you might have to use an signal generator to tune in on the stations frequency.
