Tuning Coil Inductance Variations For Radio Tuning
A survey of inductance forms for short wave tuning coils describes single layer solenoids with slides or switches for varying inductance, and discusses variometers with cylindrical or spherical windings, basket windings, spider web coils, and multi layer bank wound and duo lateral coils for long and short wave reception.
Don’ts for Early Radio Receivers Guide
A practical list of safety and setup tips for home radio hobbyists. It warns to insulate the antenna and avoid placing switches in doors, not to listen in during storms, and to prevent interference with other stations. It also cautions against wiring parallel runs, using loudspeakers with crystal sets, and connecting antennas to power poles or lighting circuits.
Annealing Method to Prevent Wire Breakage
Hard drawn copper wire used in panel connections breaks on bending or removal. Anneal the wire by heating it in a flannel or coating with tin or solder. After annealing, the end can be bent several times without breaking.
Magnet Improves Tube Sensitivity by Strategic Magnet Placement
A large horseshoe magnet placed with poles on each side of an audion tube can increase sensitivity. The effect likely arises from magnetic influence on electrons moving from filament to plate, enhancing signal flow.
Length Rules for Aerial Wires
The guidance states a single 75 foot wire suffices. shorter aerials require two wires with leading-in from the far end. For aerials 50 feet or less, use four wires and again pull leading-in from the far end.
Proposal to Increase Broadcast Wavelengths by Stations
A plan aims to expand available broadcasting wavelengths by adjusting several meter stations by 25 or more. The move targets more channel capacity across the network and could affect frequency allocations and station operations.
Radio Sparks and Signals Highlight Early Wireless Era
Edison’s discovery of current between a heated filament and a plate in a vacuum tube underpins the first amplifiers. Radio progress suffers from his deafness while Britain plans eight new stations funded by a listener fee. Forest service uses radio for fire alerts. Red Sea dead spot. wireless ideas linked to telegraph lines. companies use radio for employee entertainment.
