Radio Waves and Aircraft Relay Signals
Ether waves require good insulators and soldered connections. Strong signals come from low resistance, with minimal distortion and reduced parasitic disturbances. English radio fans hear operator reports at night from the R-33 cruiser using a 90 meter wavelength on crystal detector sets.
Wave length interference grounds for amplifying transformers
Cores of amplifying transformers should be grounded. Reverse the tickler loads if it does not escalate. A major cause of interference is the misuse of regenerative receivers. Foreign ships in Swedish harbors face trouble when their wave length interferes with commercial radio traffic.
Five Principles of Radio Receiver Operation
This article outlines the five key radio circuit principles: radio frequency amplification, detection, regeneration, reflex amplification, and audio frequency amplification. It explains the difference between radio frequency currents and audio frequency currents and describes how detectors and amplifiers in vacuum tubes enable tuning, detection, and sound output.
