- noun One that transmits.
- noun An electronic device that generates and amplifies a carrier wave, modulates it with a meaningful signal derived from speech or other sources, and radiates the resulting signal from an antenna.
- noun The portion of a telephone that converts the incident sounds into electrical impulses that are conveyed to a remote receiver.

- noun One who or that which transmits.
- noun Specifically— In telegraphy, the sending or despatching instrument, especially that under the automatic system, in which a paper strip with perforations representing the Morse or a similar alphabet is passed rapidly through an instrument called an automatic transmitter, in which contacts are made by metallic points wherever a perforation occurs, and are prevented where the paper is unpierced.
- noun In telephony, the microphonic or other apparatus, together with the funnel for receiving the voice and converging the waves of sound upon the thin iron diaphragm. See

In the wonderful system of the telephone with its miracle of intercommunication there is, as you know, at each instrument that little film of metal which we call the transmitter, into which the message is delivered, and whose vibrations are repeated scores of miles away.
Shes about the size of a dinner plate, and the transmitter is glued to her shell.
This week, however, Belkin announced its latest TuneBase FM transmitter is equipped with something called "ClearScan" technology, which can automatically seek out the clearest FM frequency to play your tunes.
Today, however, Belkin announced its latest TuneBase FM transmitter is equipped with something called "ClearScan" technology, which can automatically seek out the clearest FM frequency to play your tunes.
The Cyclers are controlled by a hidden handset but they are also robots acting on messages rather than just simple radio-controlled devices and if the message gets corrupted by interference they don't do it and if the transmitter is turned off they shut down and go to sleep until it turned back on.
They do this by a “chemical” reaction ie: a tiny amount of a substance called a neuro-transmitter is released from the the nerve ending into the junction with the next nerve (synapse).
Is it, as we suspected, based on indirect evidence, the presynaptic element of the synapse where chemical transmitter is released, or is it the postsynaptic site which contains the receptors which bind and respond to the transmitter?
But as knowledge of wave motions developed and the laws of governing them were better understood, the receiver was "tuned" to respond to the transmitter, that is, the transmitter was made to set up a definite rate of vibrations in the ether and the receiver made to respond to this rate, just like two tuning forks sounding the same note.
The transmitter is coded, like the newer Polar transmitter units, so you never have to worry about interference from other transmitters -- a common problem in race events.
I can’t however retune just the ABC and Seven to the repeater’s UHF frequencies, I have to rescan the whole lot (while it’s still stormy so it will use the repeater’s frequencies instead of the main transmitter’s VHF channels).
