Abstract

315,487. Biddington, T. A., and Field, R.. April 19, 1928. Receiving-sets, construction of. - A wireless receiver of the type having a fixed tuning coil is adapted for use on short waves by removing the original tuning coil and fitting a base strip carrying plug in socket connectors adapted to engage either a short wave coil or a strip carrying pins on which the original coil is mounted. The Figure shows the construction of the short wave coil which comprises an aperiodic coil 5, a grid circuit coil 6 and a reaction coil 7 wound on a ribbed former. A wander lead 10 is provided to short-circuit part of the grid coil to vary the wavelength.
