on video how to make a radio transmitter, build a long range AM transmitter


 how to make a radio transmitter, build a long range AM transmitter

how to make a radio transmitter, build a long range AM transmitter

Build a long range AM transmitter, homebrew radio station

How to make 1 km radio transmitter using transistor, long range FM transmitter circuit

mini-AM

How to easily make a mini FM transmitter band 88 to 108 MHz.

The frequency can be adjusted by tightening or spreading the turns of the coil or by putting a variable capacitor in place of C4. (LC circuit).

I powered the assembly with a 3.7 volt 18650 battery.

Power supply from 3 volts to 6 volts.

I changed the 9018 transistor with a Bc547 which improves the range.

A larger antenna will also provide a little more distance, experiment.

There is a way to make some changes: let others benefit.

At the end of the video: how to test an infrared remote control with a radio.

INFORMATION:

note that 27mhz CB radios are authorized without an Amateur Radio certificate up to a power of 4w with 40 AM/FM channels and 12W SSB in Switzerland.


PMR radios are authorized up to a power of 0.5W in accordance with standard RIR0507 and EN 303 405 in Switzerland


If you are thinking of getting started in the radio hobby pay attention to the regulations that must be respected and which can vary from country to country.
