help on am transmitter circuit

[Parth86]

hello

i am vead i have been trying to design my own am transmitter circuit
in books i read lots of theory but i don't know how they combined together
so i draw schematics diagram of am transmitter
i am not sure that my circuit is correct

specifications- am modulations
low level
linear amplifier
bipolar transistor

please look at diagram if i wrong please correct me

thanks in advance

you need an oscillator, which you do not have in the circuit shown. what you do have, is transistor T1 used as an audio amplifier, driving what looks like part of an RF amp (T2). what you need are an rf oscillator, a modulator stage (which takes audio and changes the amount of RF according to the audio waveform), and an RF output stage.

here's a page with some ideas http://www.techlib.com/electronics/amxmit.htm

Bear in mind that in most countries transmitters (with some exceptions) must meet certain requirements and need to be licensed to be legal.

An AM radio picks up all kinds of interference.
