The construction of an AM radio generally consists of a germanium diode crystal along with an electro magnet. In order to receive different currents, the crystal is responsible for the changing frequencies. Therefore, in order to change the frequencies, there must be something in control of the crystal. That is where the electro magnet-- an iron rod wrapped around with catshair wire connected to a power source such as a battery-- fits the job. Although the electro magnet is usually connected to a battery, it can actually use the power of the current that flows through the crystal as it takes in the energy supply of the radio waves. All that you need left is a tiny earphone that slightly contacts the surface of the germanium diode crystal.
Note: there is no harm of the radio waves that travel through your mini radio (you may be mistaken by radioactivity)

How To Build A Radio?
To build a radio you will need a receiver and a sender. This would be an antenna and some radio station sending a signal. You will also need an amplifier or speaker to hear the translated signal from the radio station. With all of these and an understanding of physics, you can build a radio, which was something I did freshman year of college.

Can radio build culture?

Why did you not use Nikola Tesla radio?
You should read about Nikola Tesla. He was one of the greatest scientists of all time, and well ahead of others of his day. He invented the radio. Some people are claiming he got the patent for his written work and that he didn't build a fuctional radio. This is not accurate. Nikola Tesla did build a radio and showed it's power which to the world.

If the player enables radio it should use either an in built antenna of use the earphones as an antenna. Nothing more to buy or build.
Why would it be difficult to build radio telescopes if they did not work well at low altitude?
Because in order to have any practical value as a research-grade instrument, a radio telescope has to be physically enormous.
