Make Low Frequency Radio: Where to Begin

[m718]

can someone tell me how to make a radio that would tune between about 1000 and 10000 Hz please. ? Or at least where to begin.

Welcome to the PF.

The antennas for those low frequencies would be prohibitively large, or at least very inefficient. What is the application?


EDIT -- This looks similar to your thread from last December:

Is it for a different application?

I would recommend starting by researching the basic principles of radio technology. This would involve understanding the concept of electromagnetic waves and how they can be used to transmit and receive information. Additionally, it would be helpful to learn about the different components of a radio, such as antennas, transistors, and frequency modulators.

Once you have a basic understanding of the principles behind radio technology, you can begin to gather the necessary materials and tools to build your own low frequency radio. This may include purchasing a radio kit or individual components, such as a variable capacitor and inductor, and assembling them according to a schematic diagram.

It is important to note that building a radio that can tune between 1000 and 10000 Hz may be a complex and challenging task, especially for someone without prior experience in electronics. It may be helpful to seek guidance from a mentor or expert in the field, or to join a community of radio enthusiasts who can provide support and advice.

In conclusion, making a low frequency radio requires a combination of knowledge, resources, and determination. By starting with the basics and seeking guidance from experienced individuals, you can begin your journey towards creating your own radio that can tune within the desired frequency range.
