Door het kiezen van de juiste radio frequentie kan je naar je favoriete radiozender luisteren, maar dan is het natuurlijk wel belangrijk dat je de radio frequentie van je favoriete radiozender weet te vinden.

Wildlife tracking collars: 215 to 220 megahertz. Radio frequency (RF) energy, in the form of radiating waves or electrical currents, has been used in medical treatments for over 75 years,[10] generally for minimally invasive surgeries using radiofrequency ablation including the treatment of sleep apnea. BBC Asian Network is available on Medium Wave in the following locations. The first radio broadcasts occurred in 1906 or so, and frequency allocation for AM radio occurred during the 1920s (The predecessor to the FCC was established by Congress in 1927.). This is roughly between the upper limit of audio frequencies and the lower limit of infrared frequencies;[1][2] these are the frequencies at which energy from an oscillating current can radiate off a conductor into space as radio waves. More detailed band designations are given by the standard IEEE letter- band frequency designations[5] and the EU/NATO frequency designations.[9]. The radio spectrum of frequencies is divided into bands with conventional names designated by the International Telecommunications Union (ITU): Frequencies of 1 GHz and above are conventionally called microwave,[8] while frequencies of 30 GHz and above are designated millimeter wave.

This is because the, When conducted by an ordinary electric cable, RF current has a tendency to reflect from discontinuities in the cable, such as connectors, and travel back down the cable toward the source, causing a condition called, This page was last edited on 8 September 2020, at 13:46.

In the 1920s, radio and electronic capabilities were fairly limited, hence the relatively low frequencies for AM radio.
