Vacuum Tube Detector Tips for Radio Signals
Guidance on adjusting filament rheostat and plate potential to fetch strong signals. Ensure tubes are properly seated and contacts clean. Check A and B battery polarity, circuit connections, grid condenser, and leaks for best reception. A three electrode tube can replace the crystal to boost loudness and stability.
Fine vacuum tube detector uses A battery potentiometer
The article explains using an A battery potentiometer of 200 to 500 ohms to finely vary plate voltage in a three electrode vacuum tube detector. It notes six volt variation possible, warns against excessive plate voltage bucking gas tubes, lists required parts and assembly, and emphasizes correct battery connections and future roles of tube functions as detector amplifier and oscillator.
Sun Dust Creates Radio Net Shielding Earth
Electrified dust from the sun forms an atmospheric envelope about the Earth at about 100 miles up that prevents wireless waves from escaping. Prof J A Fleming of University College London says this dust screen acts as a wireless speaking tube allowing long distance waves around ten miles long to travel 6,000 to 12,000 miles. Without the screen wireless energy would not cling to the Earth and would pass off into space.

How Big Is an Electron Millikan’s Oil Drop Experiment
An American, Professor Millikan of Chicago, measured an electron by observing tiny oil drops about 110,000th inch in diameter in a chamber between two controllable plates. Illuminated and viewed through a telescope, drops rose or fell by adjusting plate voltages, picking up and losing electrons. He inferred the electron charge from the effect of a single added electron.

German Radio Speed and Handling of Secret Messages
Allied readers learn how German radio operators sent rapid secret messages yet allies slowed and deciphered them. An operator used a dictaphone and wax cylinder to record a German East Africa transmission, then played it back slowly to transcribe the dots and dashes for decoding. This showed how press messages from Europe to America were ultimately read by the allies.
