A two-way radio (or walkie-talkie) is a hand-held, portable, transceiver used for voice communication over a short distance. It operates by transmitting and receiving an FM (Frequency Modulated) signal on a specific frequency.
Most two-way radios have a scanning feature which allows you to search for and automatically lock onto the strongest signal. This is useful when there are multiple users in the area and you want to connect with the one with the strongest signal.
Most two-way radios also have a CTCSS (Continuous Tone-Coded Squelch System) or DCS (Digital Coded Squelch) feature. This allows you to manually select a specific tone or digital code which will be used to open the squelch. This is useful when there are multiple users in the area using the same frequency, as it will help to prevent interference.
The table below lists the most common two-way radio frequencies in the United States.

What frequencies do 2 way radios use?
2 way radios use a variety of frequencies to communicate. The most common frequency range for 2 way radios is between 136 MHz and 174 MHz. This range is divided into a number of channels, which users can select to communicate on.
There are also a number of other frequency ranges that 2 way radios can use. Some radios may be able to communicate on frequencies as low as 30 MHz or as high as 512 MHz. This can be helpful if users need to communicate in a particularly wide area, or if they need to avoid interference from other devices.
Most 2 way radios also use a tone of voice to indicate when a transmission is being made. This can be helpful for users who are trying to listen for specific transmissions. Different tones can indicate different types of messages, so users can know what to expect before they even start listening.
By understanding the different frequencies that 2 way radios use, users can better select the right radio for their needs. This can help to ensure that communications are clear and easy to understand.
What is the best channel for 2 way radio?
When it comes to two-way radios, there are a lot of factors to consider. But one of the most important is the channel. What’s the best channel for 2 way radios?
There’s no one definitive answer to that question. It depends on your specific needs and the radios you’re using. But here are some things to keep in mind when choosing a channel for your two-way radios.
First, you need to consider the range of your radios. The farther apart you need to be able to communicate, the higher the channel number you’ll need.
Second, you need to think about the type of environment you’ll be using your radios in. If you’re in a congested area, you’ll want a channel with less traffic. But if you’re in a rural area, you’ll want a channel with more range.
Third, you’ll need to consider the tone of voice you need for your radios. Some channels are better suited for emergency communications, while others are better for casual conversations.
Finally, you’ll need to check with your specific radio manufacturer to see which channels are supported by your radios. Not all channels are supported by all radios.
So, what’s the best channel for 2 way radios? It depends on your specific needs. But with a little bit of research, you should be able to find the right channel for your needs.
What radio frequency can civilians use?
The FCC has set aside certain radio frequencies for civilian use. The specific frequencies vary depending on the service, but a few examples include:
-Frequencies for AM and FM radio stations
-The ” Citizens Band ” (CB)
-The “Personal Radio Service” (PRS)
Each service has its own specific frequencies and rules for use. For example, the CB service is limited to 40 channels, and the PRS service has a range of about 1 mile.
It’s important to check with the FCC before using any of these frequencies, as unauthorized use can result in fines or other penalties.
Which frequencies do walkie-talkies use?
Walkie-talkies are a great way to communicate with others in close proximity without having to shout. They use a specific frequency range to send and receive messages, so it’s important to know which frequencies do walkie-talkies use.
Most walkie-talkies use the UHF frequency range, which ranges from 400-512 MHz. This frequency range is perfect for walkie-talkies because it has a long range and doesn’t travel through walls or other objects very well. This means that the person you’re trying to talk to won’t hear the message if they’re too far away or if there’s something blocking the signal.
There are a few different UHF frequency bands that walkie-talkies can use. The most common frequency bands are the A, B, and D bands. The A band is from 470-512 MHz, the B band is from 380-470 MHz, and the D band is from 300-380 MHz.
Each frequency band has different channels that can be used. The A band has 40 channels, the B band has 16 channels, and the D band has 8 channels.
Walkie-talkies can also use the VHF frequency range, which ranges from 136-174 MHz. This frequency range is perfect for communicating with other devices that use VHF frequencies, such as police radios and emergency services.
The VHF frequency range has a shorter range than the UHF frequency range, but it travels through walls and other objects better. This means that the person you’re trying to talk to will be able to hear the message even if they’re far away or if there’s something blocking the signal.
The VHF frequency range has 12 channels, which are all in the same band.
It’s important to note that not all walkie-talkies use the UHF or VHF frequency range. Some walkie-talkies can use both frequency ranges, while others can only use one or the other.
So, which frequency do walkie-talkies use? Most walkie-talkies use the UHF frequency range, which ranges from 400-512 MHz.
Can a two-way radio be traced?
Can a two-way radio be traced?
This is a question that many people have asked, and the answer is not a simple one. There are a few factors that need to be considered when answering this question. The first is whether or not the radio is transmitting. If it is not transmitting, then it is much more difficult to trace. The second factor is the type of radio that is being used. There are a few different types of radios, and each one has its own advantages and disadvantages when it comes to tracing.
The most basic type of radio is a voice-only radio. These radios do not have the ability to transmit data, so they are much more difficult to trace. If someone is using a voice-only radio, it is very difficult to track them down. The only way to do so would be to track the signal of the radio, and even then it would be difficult to get a precise location.
The next type of radio is a data radio. These radios are much more common than voice-only radios, and they have a variety of different functions. One of the most common functions of a data radio is to transmit GPS data. This means that the location of the radio can be tracked very easily. If someone is using a data radio, it is very easy to track them down.
The final type of radio is a trunked radio. Trunked radios are the most common type of radio used by law enforcement. They have a variety of different functions, including the ability to transmit GPS data. This means that the location of the radio can be tracked very easily. If someone is using a trunked radio, it is very easy to track them down.
What frequencies can I use without a license?
What frequencies can I use without a license?
This is a question that many people have, and the answer can vary depending on your location. In general, unlicensed frequencies are available in the VHF and UHF bands. However, in some locations there may be restrictions on which frequencies can be used without a license.
In the United States, the FCC regulates the use of radio frequencies. The FCC has a number of rules and regulations regarding the use of unlicensed frequencies. In general, unlicensed frequencies are available in the VHF (Very High Frequency) and UHF (Ultra High Frequency) bands. However, there may be restrictions on which frequencies can be used without a license in specific locations.

Is CB Channel 9 still monitored?
CB channel 9 is still monitored by the police and other emergency services, but it is not as closely watched as it used to be. The channel is primarily used for emergencies, so it’s important to use it responsibly.
