In electronics and telecommunications a transmitter or radio transmitter is an electronic device which, with the aid of an antenna, produces radio waves. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves. In addition to their use in broadcasting, transmitters are necessary component parts of many electronic devices that communicate by radio, such as cell phones, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons. The term transmitter is usually limited to equipment that generates radio waves for communication purposes; or radiolocation, such as radar and navigational transmitters. Generators of radio waves for heating or industrial purposes, such as microwave ovens or diathermy equipment, are not usually called transmitters even though they often have similar circuits.
FM transmitter may refer to:
FM broadcasting is a VHF broadcasting technology, pioneered by Edwin Howard Armstrong, which uses frequency modulation (FM) to provide high-fidelity sound over broadcast radio. The term "FM band" describes the frequency band in a given country which is dedicated to FM broadcasting. This term is slightly misleading, as it equates a modulation method within a range of frequencies.
Throughout the world, the FM broadcast band falls within the VHF part of the radio spectrum. Usually 87.5 to 108.0 MHz is used, or some portion thereof, with few exceptions:
The frequency of an FM broadcast station (more strictly its assigned nominal center frequency) is usually an exact multiple of 100 kHz. In most of South Korea, the Americas, the Philippines and the Caribbean, only odd multiples are used. In some parts of Europe, Greenland and Africa, only even multiples are used. In the UK odd or even are used. In Italy, multiples of 50 kHz are used. There are other unusual and obsolete standards in some countries, including 0.001, 0.01, 0.03, 0.074, 0.5, and 0.3 MHz. However, to minimise cross-channel interference, stations operating from the same or geographically close transmitters tend to keep to at least a 0.5 MHz frequency separation even when closer spacing is technically permitted, with closer tunings reserved for more distantly spaced transmitters as potentially interfering signals are already more attenuated and so have less effect on neighbouring frequencies. RCA stereo models use multiples of 0.2 MHz, starting at 87.50 and ending at 107.90.

The Nulaxy KM19 Bluetooth FM Transmitter allows you to turn even the oldest most analog car into a Smartcar. Maybe you didn't have the option to get a handfree system when you bought your car or you rent a lot and don't like syncing your phone up to rental cars well the KM19 is your perfect companion. Good: It works over Bluetooth so unlike the FM Transmitters of old you don't have to attach your phone with a cable for it to work. Good: The KM19 has two USB ports on the side of it so you can both charge a device and plug in a flash drive for playing media. You can load up a thumb drive full of music plug it in and play it through your car's stereo system. Good: It has a MicroSD slot so you can also load a memory card with songs and have them ready to play in the car. Good: The KM19 has an...

Complete instructions for this episode of Weekend Projects can be found at http://makezine.com/projects/super-simple-fm-transmitter/ FM transmitters can be complicated to build, but not this one — it's about the easiest you can possibly make. And though the science of radio is well understood, there's a magical, emotional quality about it that we don't often stop to appreciate. Building your own radio receiver — or better yet, transmitter — makes it real again. You will not forget the first time you pick up a transmission broadcast from a device you soldered together, yourself, from a few bits of copper, carbon, plastic, and wire.

How to make FM Radio Transmitter How to make mini FM Transmitter How to make FM Transmitter Build A Long Range FM Transmitter A short range FM transmitter is a low-power FM radio transmitter that broadcasts a signal from a portable audio device (such as an MP3 player) to a standard FM radio. Most of these transmitters plug into the device's headphone jack and then broadcast the signal over an FM broadcast band frequency, so that it can be picked up by any nearby radio. This allows portable audio devices to make use of the louder or better sound quality of a home audio system or car stereo without requiring a wired connection. Being low-powered, most transmitters typically have a short range of 100–300 feet (30–100 meters), depending on the quality of the receiver, obstructions and elevati...

A late night maintenance visit to the KKUA transmitter atop the Ulupalakua Ranch on Maui. KKUA is the Hawaii Public Radio station serving Maui, Moloka`i, Lana`i and West Hawai`i island. It operates with 56,000 watts from about 5,000 feet above sea level. The transmitter is operating with 19,000 watts output. Programming comes in via microwave from Honolulu, 105 miles west of the site. The big white boxes with copper coaxial line on top is the three station combiner. This combiner is manufactured by Shively Labs in Maine. They also designed and manufactured the KKUA antenna system up on the tower. Right now, only two stations feed the combiner and antenna.

She is red light
She means blood
Hail your streetcar
Save me one
For the money
For the show
Keep your head
On trade your hope
And the fashion
Of her words
Keeps her hold tight
On the world
As you're turning
All is quiet
She takes pale white
Autumn days
[Chorus:]
She is redlight
She means blood
She's a killer
She's a whore
Not the moonlight
In the hall
I can't heal her
Turn her heart
I've felt this way
Many times before
Crossed this space to you
You're sending out
These waves
Across my heart
Always keep me sane
Always keep me warned
Always keep us fair
I can't keep on
Kill the children
Saves the world
Keeps momentum
Kills your words
She keeps secrets
With her hands
I have fear now
Of her height
[Chorus 2x]
I've felt this way
Many times before
Crossed this space to you
You're sending out
These waves
Across my heart
Always keep me sane
Always keep me warned
Always keep us fair
