Walkie talkie frequency and channel are important elements in radio. You might have come across these terms before, but what do they really mean? Don’t worry, I’ll explain them in simple terms to make everything clear.
Frequency
Imagine that you and your friends are running on the playground. If you are running on the same track, it is easy for you to bump into each other. In fact, there are different tracks on the playground, so you can run on your own track without interfering with each other. It is the same as frequency for two way radio. The frequency of the walkie-talkie is like the track on the playground. Frequency is the “speed” of radio waves, and different frequencies are like different tracks. Walkie-talkies transmit sound through radio waves, and if everyone uses the same frequency, the sound will “crash”, leading to communication chaos. Therefore, in order for everyone to clearly hear each other's voices, walkie-talkies need to have different frequencies.
Channel
Frequency on the “small grid” frequency is like a big road, and the channel is a small grid on the road. Imagine a big road with many lanes, each lane can be traveling on different vehicles. Channels are these lanes, which divide a frequency into many small compartments so that more people can communicate on the same frequency without interfering with each other.
For example, if you and your friends are talking on walkie-talkies in a park, you can set them on the same channel (like channel 1). Another pair of friends can use walkie-talkies, but they are set on channel 2. You all can use walkie-talkies at the same time without hearing each other's voices, as if they were driving on different lanes of traffic.
Why you need to set different frequencies and channels?
<!--[if !supportLists]-->1. <!--[endif]-->Avoid interference: If everyone uses the same frequency and channel, the sound will be mixed together, just like many people talking at the same time in a room, you can't hear who is talking. By setting up different frequencies and channels, everyone can communicate clearly in their own “cubicle”.
<!--[if !supportLists]-->2. <!--[endif]-->Meet different needs: Different scenarios require different communication methods. For example, police officers need a dedicated frequency and channel when they are on duty, so that their communication will not be interfered by others. And outdoor enthusiasts can use another frequency and channel when hiking to facilitate the contact between them.
How to set frequency and channel
Setting frequency and channel is actually very simple. Most walkie-talkies have a knob or button through which you can select different frequencies and channels. For example, you turn the knob to “frequency 1”, and then select “channel 1”, so it is set. If you need to talk to someone else, just make sure your frequency and channel settings are the same.
Some common frequencies and channels
Public channels: These channels are open and can be used by anyone. For example, some outdoor walkie-talkies have public channels that are suitable for use in parks, shopping malls, and other places.
Dedicated channels: These channels are dedicated to some specific people or organizations, including police officers, firefighters. use special channels that are not available to ordinary people.
Conclusion
Frequency and channel are the key to make the walkie-talkie work properly. Frequency is like the main road and channel is like the small grids on the main road. By setting different frequencies and channels, we can make communication clearer and more efficient. Next time you use walkie-talkie, remember to check the frequency and channel settings, so that you can chat with your friends better.
