So with at least two adjustments available to tune to just one frequency, there are often a variety of settings that will tune the preselector to a frequency in its middle-range.

For the narrowest bandwidth ( highest " Q " ), the preselector is tuned using the highest inductance and lowest capacitance for the desired frequency, but this produces the greatest loss.

Gerard's major changes to the pre-war design were to fit a preselector gearbox and to change the Zoller-type supercharger for a smaller, but more efficient Murray-Jamieson design.
34.
For lowest loss ( and widest bandwidth ), the preselector is tuned using the lowest inductance and highest capacitance ( and the lowest " Q ", or least selectivity ) for the desired frequency.
35.
The wider bandwidth allows interference through from more nearby frequencies, but reduces the need for retuning the preselector while tuning the receiver, since any one low-inductance setting for the preselector will pass many nearby frequencies.

A car enthusiast since the age of four, he owned a succession of interesting machines ranging from a Fiat Topolino, several Lancias, a Hispano-Suiza, a preselector gearbox Delage, and a special-bodied Jowett Jupiter.

The Marchant, however, has, for every one of its ten columns of keys, a nine-ratio " preselector transmission " with its output spur gear at the top of the machine's body; that gear engages the accumulator gearing.

An interesting feature was preselector gear-change, similar to those in Leyland buses, commanded by a smallish gated lever installed by the steering wheel, with a reversed gate, with first gear to the right and up, and fourth gear to the bottom and left.

One of the ingenious features of Dingo's design was the transmission which included a preselector gearbox and fluid flywheel that gave five speeds in both directions, another was a four-wheel steering system made possible by the H-drive drivetrain, giving a tight turning circle of
