radio detector in a sentence

• Marconi used this device as a radio detector.
• Damped waves were excellent for radiotelegraph with early radio detectors, but are very wasteful of bandwidth.
• At 2 am, a senior police officer alerted radio detector vans to track down the gang's exact location.
• He soon found that with higher quality crystals their finicky behaviour went away, but so did their ability to operate as a radio detector.
• Spacecraft may also bring radio detectors at extremely long wavelengths ( as long as a few kilometers ) that cannot propagate through the ionosphere.
• The carbon rod and two carbon blocks, which he would refer to as a " coherer " in 1899 is also similar to devices known as crystal radio detectors.
• Finally, the tertiary reflector brings the beam to a tight focus above it at a spot where the rays impinge on a sensitive radio detector chilled to a temperature near absolute zero.
• Other radio detectors invented for wireless telegraphy, such as the Fleming valve ( 1904 ) and the crystal detector ( 1906 ) also proved able to rectify AM signals, so the technological hurdle was generating AM waves; receiving them was not a problem.
• Before World War I, Cady investigated arc discharges and radio detectors, but during the war became interested in crystals as he worked with General Electric Company's Research Laboratory, Columbia University, and the Naval Experimental Station in New London, Connecticut, on using high-frequency sound generated by piezoelectricity to detect submarines.
• The tube was relatively immune to vibration, and thus vastly superior on shipboard duty, particularly for navy ships with the shock of weapon fire commonly knocking the sensitive but delicate galena off its sensitive point ( the tube was in general no more sensitive as a radio detector, but was adjustment free ).
• It's difficult to see radio detector in a sentence .
