Are AM transmitters legal?

UNLICENSED LEGAL AM The legal limit for AM broadcasting is 100 milliwatts, with a maximum antenna length of about 10 feet (this is highlighted in Part 15 as well). A note about Part 15 – it does not require that you use a transmitter that has been type-accepted, so it is “legal” to use a homemade transmitter or a kit.

How do you transmit AM radio?

In order to generate the radio frequency signal for AM radio transmission, the information contained in the original sound signal must be put in a form that can be sent to a great distance. When information from a voice is broadcast on an AM radio station, an electrical image of the sound is made by a microphone.

Is there an AM radio transmitter?

AM broadcasting is radio broadcasting using amplitude modulation (AM) transmissions. It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave (also known as “AM band”) transmissions, but also on the longwave and shortwave radio bands.

Can you convert an AM radio to FM?

If you inderstand electronics and radio, there is no real way to convert an AM radio’s circuitry into receiving FM, without adding a lot of additional componets, coils amps etc. By the time you do that, you could have bought an AM/FM set made in those years that would fit into your dash.

How exactly does an FM transmitter work?

Re: How exactly does an Fm transmitter work? FM (frequency modulation) simply means the transmitter output frequency is proportional to the amplitude of the input (modulating) signal. The larger or louder the input signal the higher the transmitter frequency. The amplitude of the transmitted signal is constant – only its frequency changes.
