These electrons interact with the radio-frequency magnetic field of the induction coil and are accelerated first in one direction, then the other, as the field changes at high frequency ( usually 27. 12 MHz ).

This machine's hardware clock speed was almost four times that of the 6600 ( 36 MHz vs. 10 MHz ) a 27. 5 ns clock cycle, and it offered considerably more than four times the total throughput.

After World War II, the FCC moved FM to the frequencies between 88 and 108 MHz on June 27, 1945.

BSS ( DBS direct broadcast satellites ) normally carry 16 to 32 transponders of 27 MHz bandwidth running at 100 to 240 watts of power, allowing the use of receiver antennas as small as 18 inches ( 450 mm ).

In 1958 the Class D CB service was moved to 27 MHz, and this band became what is popularly known as CB.

Part 95 of the Code of Federal Regulations regulated the Class D CB service, on the 27 MHz band, as of the 1970s.

Before CB was authorized in Australia, there were hand-held 27-MHz " walkie-talkies " which utilised several frequencies between the present CB channels, such as 27. 240 MHz.

After peaking in the 1970s and early 1980s, the use of 27 MHz CB in Australia has fallen dramatically due to the introduction of 477 MHz UHF CB ( with FM and repeaters ) and the proliferation of cheap, compact handheld UHF transceivers.

The frequency band is HF, 26. 9650 MHz to 27. 4050 MHz ( 40 channels ), power output is 4 watts for AM and FM and 12 watts PEP for SSB.

By 1980, CB radio was becoming a popular pastime in Britain ; as late as the summer of 1981 the British government was still saying that CB would never be legalized on 27 MHz, proposing a UHF service around 860 MHz called " Open Channel " instead.

However, in November 1981 ( after high-profile public demonstrations ) 40 frequencies unique to the UK, known as the 27 / 81 Bandplan using FM were allocated at 27 MHz plus 20 channels on 934 MHz ( 934. 0125 to 934. 9625 MHz with 50-kHz-spacing ).

MPT 1320 also restricted antennas to a maximum length of 1. 5 metres, with base loading being the only type permitted for 27 MHz operation.

On 1 September 1987 the UK added the usual 40 frequencies ( 26. 965 – 27. 405 MHz ) used worldwide, for a total of 80 channels at 27 MHz ; antenna regulations were further relaxed, and the 934 MHz band was withdrawn in 1998.

A second crash cymbal is common, typically an inch or two larger or smaller than the 16 ", with the larger of the two to the right for a right-handed drummer, but a big band may use crashes up to 27 " and ride up to 24 " or very occasionally 26 ".

The band released a new album on 27 March 2005, entitled Waiting for the Sirens ' Call, their first with new member Phil Cunningham.

* November 27 – American Indian Wars – Battle of Washita River: In the early morning, United States Army Lieutenant Colonel George Armstrong Custer leads an attack on a band of Cheyenne living on reservation land with Chief Black Kettle, killing 103 Cheyenne.

On December 27, 2006, Incubus launched the " I Dig Incubus " contest, in which participants cut together clips of the band performing their single " Dig ", to form a complete music video.

Four years later, on November 27, 1868, George Armstrong Custer and his troops attacked Black Kettle's band at the Battle of Washita River.

The band is estimated to have sold 27 million albums as of 2004.

On January 27, 1968, Beefheart achieved one of his most memorable live performances, when the band performed in the MIDEM Music Festival on the beach at Cannes, France.

" After being accepted into the Army, Glenn ’ s civilian band played its last concert in Passaic, New Jersey, on September 27, 1942.

While flyting with Atli, Hrímgerðr says that she had seen 27 valkyries around Helgi, yet one particularly fair valkyrie led the band:

The old MPT 1320 27 / 81 band will continue to be available for the foreseeable future.

* Central High School ( became Central Junior High School in 1955 and was partially destroyed by fire on February 27, 1966, when the band room, cafeteria and 31 classrooms burned )

Abe Cunningham, ( born July 27, 1973 ), is an American musician, he is the drummer of the alternative metal band Deftones.

On February 27, 2012, Furay announced that the band are on indefinite hiatus.

On the heels of its belated hit single, Styx signed with A & M Records and released Equinox ( 1975 ), which sold well and yielded a minor hit in " Lorelei ", No. 27 in the U. S. More importantly, it contained the rock anthem " Suite Madame Blue ", which gained the band considerable recognition and airplay on FM radio in the relatively new Album Oriented Rock ( AOR ) format.

Oasis tribute band No Way Sis released a cover of " I'd Like To Teach The World To Sing ", entering the British charts at No. 27 in 1996.

On 27 September 2006, amateur radio transmissions in the 30 m band were affected by an English-language " Russian Man " number station at 1740 UTC.

It entered the Billboard Hot 100 at Number 76, rising to 27 in October 2008, giving Rossdale his first Top 40 hit since the days when he fronted the post-grunge band Bush.

Glen Matlock ( born 27 August 1956, Paddington, West London ) is an English musician best known for being the bass guitarist in the original line-up of the punk rock band the Sex Pistols.

On 27 November 2011 The International Swingers, a band comprising Glen Matlock, Clem Burke ( of Blondie and Romantics ), James Stevenson ( Gene Loves Jezebel, Chelsea, The Alarm ), Gary Twinn ( Supernaut, Twenty Flight Rockers ), played a warmup gig in LA before a 10 date tour of Australia.

These electrons interact with the radio-frequency magnetic field of the induction coil and are accelerated first in one direction, then the other, as the field changes at high frequency ( usually 27. 12 million cycles per second ).

As a result, services began operating at the new higher frequency of 27 trains per hour from late July 2011, and this should increase to 30 per hour in 2012.

Thus the NTSC color subcarrier ended up as 3. 57954545 MHz ( actually 315 / 88 MHz ), the line scan frequency as 15734. 27 Hz and the frame rate 29. 97 Hz ( exactly 30 / 1. 001 Hz ).

The majority of the unlawful users continued in their insistence on a 27 MHz system, although for a locally available Citizen's Band system, 27 MHz is actually a very poor choice of frequency.

The UK channels that were legalised on 2 November 1981 were on two blocks of frequencies: 40 channels on the 27 MHz band and 20 channels on the 934 MHz band, both of which used FM ( frequency modulation ) and both unique to the UK.

The CB lobby was appeased, until they saw the fine print – the new 27 MHz band used an odd channel offset and frequency modulation, so it was incompatible with the American system.

In addition a calling frequency was allocated, 27. 555 MHz on Upper Side Band.

Schötz & Eklund ( 2011 ) studied purring in four domestic cats and found that the fundamental frequency varied between 20. 94 and 27. 21 Hz for egressive phases and between 23. 0 and 26. 09 Hz for ingressive phases.

Most commercial machines operate at a frequency of 27. 33 megahertz and a wavelength of 11 meters.

The modified Atkins diet reduces seizure frequency by more than 50 % in 43 % of patients who try it and by more than 90 % in 27 % of patients.

Heathrow Terminal 5 station opened on 27 March 2008, but the frequency of trains on the Heathrow branch of the Piccadilly Line remained the same as previously, with services from Hatton Cross to Heathrow split.

When the press comes together, high frequency waves ( usually 27. 12 MHz ) are passed through the small area between the die and the table where the weld takes place.

MATV Channel 6 was broadcast in Leicester on UHF Channel 68 ( frequency 847. 25 MHz-Horizontally polarised ) from 27 May 1999 until late 2009.

The former frequency of this channel on Eurobird, 11. 260Ghz ( Vertical, Symbol Rate 27. 5Mbaud, FEC 2 / 3 ) currently carries a standard colour bar test pattern.

An addition to pirate radio, particularly in the late 1990s has been a number of Catholic churches, particularly in rural areas, who broadcast their services at the high frequency end of the FM band, or on frequencies around 27 MHz ( an arrangement not permitted by legal 27 MHz CB ) for parishioners who cannot attend personally.

Shortly afterwards the authorities introduced a new licence scheme ( similar to one in the UK ) that would allow a frequency band just above the legal 27 MHz CB band to be used for this purpose.

In total, 27 applications were received for the frequency ; including Dufferin Communications, applications were also filed by MZ Media, Astral Media, Newcap Radio, Larche Communications, the Canadian Broadcasting Corporation, Trust Communications, Intercity Broadcasting, CHIN Radio / TV International, La Coopérative Radiophonique de Toronto and numerous ethnic broadcasters, as well as a new student group from Ryerson University who have pledged to launch a new campus station that would be organized and governed very differently from CKLN.

A specific example is the Mariazeller narrow gauge railway in Austria, operating with single phase AC with a frequency of 25 Hz, which has its own traction current lines with an operating voltage of 27 kV.

It currently airs in Santiago on digital frequency channel 27 ( ISDB-Tb ) for HDTV.
