A broadcaster may opt to use a standard-definition ( SDTV ) digital signal instead of an HDTV signal, because current convention allows the bandwidth of a DTV channel ( or " multiplex ") to be subdivided into multiple digital subchannels, ( similar to what most FM radio stations offer with HD Radio ), providing multiple feeds of entirely different television programming on the same channel.

As well as being home to RTÉ Radio, Dublin also hosts the national radio networks Today FM and Newstalk, and numerous local stations.

There are also numerous community and special interest stations, including Dublin City FM ( 103. 2 MHz ), Dublin South FM ( 93. 9 MHz ), Liffey Sound FM ( 96. 4 MHz ), Near FM ( 90. 3 MHz ), Phoenix FM ( 92. 5 MHz ), Raidió na Life ( 106. 4 MHz ) and West Dublin Access Radio ( 96. 0 MHz ).

Radio DJs or radio personalities introduce and play music that is broadcast on AM, FM, shortwave, digital, or internet radio stations.

FM radio programming, high-speed Internet, telephone service, and similar non-television services may also be provided through these cables.

A low-frequency message signal ( top ) may be carried by an AM or FM radio wave.

FM signals may be detected using a discriminator, ratio detector, or phase-locked loop.

ACI may be caused by inadequate filtering ( such as incomplete filtering of unwanted modulation products in FM systems ), improper tuning or poor frequency control ( in the reference channel, the interfering channel or both ).

For wireless systems, they may be allocated a slice of the electromagnetic spectrum to transmit in ( for example, FM radio is often broadcast in the 87. 5 MHz-108 MHz range ).

Frequencies, power levels and modes ( such as frequency modulation ( FM ), amplitude modulation ( AM ), and single-sideband modulation ( SSB ), often vary from country to country ; use of foreign equipment may be illegal.

* An international broadcaster may use a local mediumwave or FM radio or television relay station in the target country or countries.

These on-line stations will usually attract a small and loyal audience and may go unnoticed by the authorities, unlike the real AM / FM pirates who can easily be heard and traced on a conventional radio.

In some markets, digital cable service may also include local radio stations ; where this is offered, it has largely replaced the availability of cable FM service.

FM stereo will tend to get static more quickly than the monophonic sound due to its use of subcarriers, so stations may choose to extend the usable part of their range by disabling the stereo generator.

They may use simple modulation schemes such as AM or FM, or more complex techniques such as digital coding, spread spectrum, and so on.

These signals are often received using a large outdoor antenna system connected to a sensitive TV or FM receiver, although this may not always be the case.

In addition to showing an incorrect frequency, there are two other disadvantages that can result in undesired performance ; the converter cannot downconvert in full the regular international FM band ( up to 20. 5 MHz wide ) to the only 14 MHz-wide Japanese band ( unless the converter incorporates two user-switchable downconvert modes ), and the car's antenna may perform poorly on the higher FM band.

A less common definition is radio receiver and transmitter implementations that are based on digital signal processing, but may transmit or receive analog radio transmission standards, for example FM radio.

Some digital radio systems provide in-band on-channel ( IBOC ) solutions that may coexist with or simulcast with analog AM or FM transmissions, while others are designed for designated radio frequency bands.

Use of air signal only radios ( AM / FM ) have declined in popularity with the rise of portable digital audio players, which allow users to carry and listen to the music of their choosing and may also include a radio tuner.

FM or Fm may refer to:

Special broadcast undertakings such as Internet radio, cable FM, carrier current or closed circuit stations may sometimes be known by unofficial call signs such as " CSCR ".

* Multiple modulation schemes: a few amateur HTs may allow modulation modes other than FM, including AM, SSB, and CW, and digital modes such as radioteletype or PSK31.

Since analog video is recorded by frequency-modulation of the video signal, the FM capture effect shields the signal against this noise ; however, the linear audio and ( depending on format ) chrominance signals of a video cassette may have some print effects.

The BCI may also issue licenses to institutions, such as hospitals and colleges, for the provision of low-powered FM services.

With the flip of the former CISS in Toronto from Jack FM to top 40 as Kiss FM on June 5, 2009, the CISS calls remained unchanged on this station.

This was in order for the station to have a competitor since Rogers flipped Toronto's first rhythmic top 40, Kiss 92. 5 to Jack FM on June 4, 2003 ; Kiss 92. 5 returned to the Toronto airwaves on June 5, 2009, just one day past the sixth anniversary of its 2003 flip from " Kiss " to " Jack ".

( This station would flip about a year later to country music WWLG FM 96. 7 " The Legend ", and has ironically since returned to simulcast this station.

Another former Arrow DJ, Bob Coburn was already at KLOS prior to the Arrow / Jack FM flip, and can be heard weekends at various times, as well as on " Rockline Replay " ( a live nationally-syndicated call-in show with Bob Coburn, taped Wednesday nights ).

RadioToday has reported The_Coast_ ( radio_station ) will flip to become JACK FM on July 4th 2011

At the same time as the format flip, the former " Lite FM " AC format moved to KZJK 104. 1-HD2, replacing smooth jazz.

Though the station ( the first commercial FM rock station in the Albany market ) did very well with the new format, protests over the format flip among classical music listeners were intense and a partial victory was claimed in late 1971 when the Troy Record sold WFLY to Functional Broadcasting and the station flipped to an easy listening / classical hybrid.

Resulting from KYHT's flip from the KIIS FM moniker, KFMS switched to all local programming.

The flip to hot AC was caused by previous hot AC station CHST-FM flipping to its current Bob FM format in July 2003.

WNIC was not the only Detroit FM under Clear Channel to flip formats in 2011.

Beasley Broadcasting Group launched " 102. 7 Now FM " KFRH in Las Vegas, both with similar sounding CHR / Rhythmic / Top 40 formats and there are speculations that many other CBS Radio stations might flip to the similar format.

Usually, CFBT is the # 2 FM station in Vancouver after adult contemporary sister CHQM-FM ( CFBT and CHQM were the only stations in Vancouver with those formats ; respectively until the flip to top 40 at Rogers-owned CFUN-FM ), and continues to beat CKZZ.

During this period 104 KRBE became the first American FM top-40 station in a Super Market to flip the market from " am " to " fm ", beating the legendary KILT 12 + in Arbitron.
