When I was a student of Secondary School and had to go radio repairing shops due to repair my own radio .I discovered a lot of new and interesting things from there.
Various types of devices are present there and National Panasonic Cassette (Made in Japan) also present there.
The repair man try to build a batteries on way port connection for the protection of the cassette IC .
IC was then very important part for the National Panasonic (M-543, Made in Japan) Cassette. Because IC was damaged by battery connections in several times due connection mistake. The owner had to buy a new IC for mending the Cassette.

Audio Power
How power distributed in audio and network of a radio set :
It sounds like you are interested in learning how power is distributed in audio and how a radio set works. I found some web search results that might help you with your query.
One result explains the basics of distributed audio systems, which are systems that use transformers and special amplifiers to power multiple speakers over a single cable. These systems can be used for background music, paging, or foreground music in different settings. You can read more about this topic here: [Understanding the Basics of Distributed Audio Systems](^1^).
Another result introduces the concept of audio networking, which is a way of transporting large amounts of data over Ethernet cables. This allows for flexible routing, remote control, and high-quality sound transmission. Audio networking can be used for distributed audio, as well as for recording and live sound applications. You can learn more about this topic here: [An Introduction to Audio Networking](^2^).
A third result gives an overview of commercial audio systems, which are systems that are designed for specific venues and purposes. Commercial audio systems typically include amplifiers, mixers, speakers, and sources. They can also include displays, such as TVs and projectors, for visual content. You can find out more about this topic here: [Introduction to commercial audio systems](^3^).
How does a radio set work?
A radio set is a device that can send and receive radio waves, which are a form of electromagnetic radiation. Radio waves can carry information, such as sound, images, or data, over long distances without wires. A radio set consists of two main parts: a transmitter and a receiver.
A transmitter is a device that converts a message, such as a voice or a picture, into a radio wave. It does this by modulating the amplitude, frequency, or phase of a sine wave, which is a smooth and regular oscillation of voltage or current. The transmitter then sends the modulated sine wave through an antenna, which is a metal conductor that radiates the radio wave into the air.
A receiver is a device that picks up the radio wave from the air and converts it back into the original message. It does this by demodulating the sine wave, which is the opposite process of modulation. The receiver then amplifies the signal and outputs it to a speaker, a screen, or another device. The receiver also has an antenna, which is usually tuned to the same frequency as the transmitter.
There are different types of radio sets for different purposes and applications. For example, there are AM and FM radios for broadcasting music and news, ham radios for amateur communication, walkie-talkies for short-range communication, cell phones for wireless telephony, Wi-Fi routers for wireless internet, GPS receivers for navigation, and many more.
If you want to learn more about how radio sets work, you can watch some videos or read some articles that I found for you:

What is the difference between AM and FM radio?
The difference between AM and FM radio lies mainly in how information is encoded, in a process called modulation, onto electromagnetic signals. AM radio works by varying the amplitude of a radio wave to carry the audio signal. The audio signal is superimposed on the carrier wave’s amplitude, causing the wave to fluctuate up and down in strength¹.
FM radio works by varying the frequency of a radio wave to carry the audio signal. The audio signal is superimposed on the carrier wave’s frequency, causing the wave to shift back and forth in cycles².
AM and FM radio have different advantages and disadvantages. AM radio has poorer sound quality compared with FM radio, but is cheaper and can be transmitted over long distances. It has a lower bandwidth so it can have more stations available in any frequency range². FM radio has better sound quality due to higher bandwidth, and is less prone to interference than AM radio. However, FM signals are impacted by physical barriers, such as buildings or mountains¹.
AM radio operates from 535 to 1705 kHz (kiloHertz), and your radio goes up 10 kHz each time you move its dial⁵. FM radio operates between 88 to 108 MHz (megaHertz), and your radio goes up 200 kHz each time you change its dial⁵.

Can you explain how Wi-Fi works?
Sure, I can explain how Wi-Fi works in simple terms. Wi-Fi is a technology that allows devices to communicate wirelessly using radio waves. Here are the basic steps of how Wi-Fi works:
- First, you need a device that can send and receive radio waves, such as a router, a smartphone, or a laptop. These devices have a Wi-Fi chip that can convert data into radio waves and vice versa.
- Second, you need an internet connection that can provide data to your router. This can be through a cable, a satellite, or a cellular network. Your router acts as a bridge between the internet and your Wi-Fi devices.
- Third, you need to set up a Wi-Fi network that can connect your router and your devices.
You can do this by choosing a name and a password for your network, and configuring some settings on your router. You can also use a Wi-Fi extender or a mesh network to boost your signal and cover a larger area.
- Fourth, you need to join your devices to your Wi-Fi network. You can do this by selecting the network name on your device and entering the password.
Once connected, your device can access the internet and communicate with other devices on the same network.
- Fifth, you need to enjoy the benefits of Wi-Fi. You can browse the web, stream videos, play games, download files, and more without using any wires. You can also use Wi-Fi to share files, print documents, control smart home devices, and more within your network.
Wi-Fi uses two radio frequencies: 2.4 GHz and 5 GHz. These frequencies are divided into multiple channels that can carry different amounts of data. The higher the frequency, the faster the data transmission, but the shorter the range.
The lower the frequency, the slower the data transmission, but the longer the range. You can choose the best frequency and channel for your Wi-Fi network depending on your needs and preferences.
Wi-Fi is an amazing technology that makes our lives easier and more convenient. However, it also has some disadvantages, such as security risks, interference issues, and health concerns.
You can take some measures to protect your Wi-Fi network from hackers, such as using strong passwords, encryption methods, firewalls, and antivirus software. You can also avoid interference from other devices or networks by changing your frequency or channel or moving your router to a better location.
You can also reduce your exposure to radio waves by limiting your Wi-Fi usage or turning off your devices when not in use.
I hope this helps you understand how Wi-Fi works. If you want to learn more about Wi-Fi, you can check out some of the web search results that I found for you:
