Low frequency signal are not able to get propagated throught longer distance. So it is to be carried by a carrier wave. Hence high frequency carrier wave is to be generated by the help of an oscillator. So we need an oscillator here a crystal oscillator to produce high frequency carrier waves.

Which oscillator circuit uses a tapped coil in the tuned circuit?
Several oscillator designs use a tapped coil in the tuned circuit. The most common is the Hartley oscillator.
Which component of an AM transmitter generates the carrier frequency?
The oscillator circuit, which is usually quartz crystal controlled with the quartz crystal in a temperature regulated oven to stabilize its resonant frequency.
What are the component of transmitter?
Power supply, oscillator, modulator, and amplifier.
What the major components of a colpitts oscillator?
1.CE amplifier circuit 2.LC oscillator circuit
What component of an AM transmitter generates the carrier frequency?
The classic AM transmitter layout is a master oscillator, followed by a "pen", or penultimate amplifier, followed by a PA or power amplifier. The master oscillator, which is probably crystal controlled, generates the carrier frequency.
Why is a crystal oscillator required in a radio transmitter?
SOME kind of oscillator is required, to create the AC signal that will be modulated, amplified, and eventually sent up to the antenna to be transmitted. It doesn't have to be a crystal oscillator, though.
What is blocking oscillator?
The oscillator which is blocked by using transformer is called a blocking oscillator. Generally, the primary is given to the base and secondary is given to the collector of the transistor used in the oscillator circuit.
What what is an oscillator?
a circuit that produces a continuously oscillating signal.
What is a local oscillation?
A local oscillator is used in a superheterodyne radio circuit for example.The incoming radio frequency is mixed with an internal local oscillator circuit to generate a new intermediate frequency (IF) .The local oscillator usually runs at a frequency of 470kHz and is generated by an inductor and capacitor(LC oscillator)
What is the purpose of an oscillator crystal?
"A circuit within a computer that creates a series of pulses that pace the computer's electronic system. The oscillator clock synchronizes, paces and coordinates the operations of the computer's circuit." -- webopedia

What type of feedback used in the oscillator circuit?
There are many different types of oscillator circuits, the majority of which use positive feedback.
