Hi Steve,
A rotary inductor will require a number of turns of the control knob to go
from one end to the other. At one end the entire value of the coil is in
the circuit - at the other, almost no inductance is left.
It shouldn't be too hard, once you know the number of turns end to end, to
learn/remember where to stop tuning for a particular frequency.
Hope this helps.
