Much of 2-meter FM operation uses a radio repeater, a radio receiver and transmitter that instantly retransmits a received signal on a separate frequency.
The 27 MHz CB27/81 Bandplan is a list of the channel frequencies for FM CB radio in the United Kingdom.
Along with Bexhill College the school operates Bexhill FM, a Restricted Service Licence FM frequency station which broadcasts for a few weeks a year to the Bexhill area.
In 1948, Jim and Hugh, Jr. started a companion FM station, the call letters of which were initially WHAJ-FM (for Hugh and Jim).
FM with a bandwidth of 16 kilohertz (25 kHz in Norway) is used.
In time, problems with sources of electrical noise showed that frequency modulation (FM) was superior for its ability to cope with vehicle ignition and power line noise.
From 2004 until 2009, a small low-powered FM station (KMZM 96.5 then 96.7), which was receivable only near and in the town, operated from one of the houses.
As for the media radio, there are amplitude modulation stations such as Radio FM and 1000, radio Ybyty Rok, Pan American, Yaguarón, Oda, Mensajera, and Carapeguá Colmenar.
Analogue PMR uses eight FM channels separated by 12.5 kHz from each other.
It is analogous to Pulse-Width Modulation (PWM), in which the magnitude of an analog signal is encoded in the duty cycle of a square wave.
Ultra high frequency | Frequency modulation | frequency | High frequency | Very high frequency | frequency modulation | Extremely high frequency | Radio-frequency identification | Pulse-width modulation | modulation | Medium frequency | Frequency | Cambridge Low Frequency Synthesis Telescope | ultra high frequency | Super high frequency | Single-sideband modulation | low frequency | Frequency Modulation | Frequency-division multiplexing | FreQuency | Amplitude modulation | Utility frequency | Orthogonal frequency-division multiple access | Nyquist frequency | modulation (music) | Modified Frequency Modulation | Low-frequency oscillation | Low-frequency effects | Low frequency | Living on Another Frequency |
On November 7, 1994, WXYC (89.3 FM Chapel Hill, NC USA) became the first traditional radio station to announce broadcasting on the Internet.
It utilizes a frequency-agile mode with 31 different frequencies, has a large band of ECCM operating parameter frequencies, and uses linear FM compression.This system can simultaneously track up to 100 targets and can feed the data to missile-interceptor batteries.
Compare to the modulation index for frequency modulation.
Narrowband Frequency modulation is used exclusively, so that the capture effect will select the stronger of two transmitters wherever one predominates.
Radio KLF was a radio station based in Helsinki, broadcasting on FM on the frequencies 100.0 MHz (Helsinki), 101.9 MHz (Turku), 101.6 MHz (Tampere) and 98.1 MHz Oulu.
On 26 June 2006, RTBF International began broadcasting in FM in Kinshasa on 99.2 MHz.
Stochastic screening or FM screening is a halftone process based on pseudo-random distribution of halftone dots, using frequency modulation (FM) to change the density of dots according to the gray level desired.
One of the station's listeners was the inventor of frequency modulation, Edwin Howard Armstrong.
