Two Way Radio Frequencies
A two way radio transmits voice or data over a radio frequency. The two way radios used today can be divided into two categories: Analog and Digital.
Analog radios use a continuous range of frequencies to transmit voice or data. The transmitted signal is not compressed, so the quality of the transmission is usually very good. However, analog radios are more susceptible to interference from other electronic devices.
Digital radios use a compressed transmission format. This format allows for more channels to be transmitted over the same frequency. The quality of the transmission is usually not as good as an analog transmission, but the digital radios are much less susceptible to interference.
Most two way radios operate in the VHF (Very High Frequency) or UHF (Ultra High Frequency) ranges. VHF frequencies range from 30 MHz to 300 MHz, while UHF frequencies range from 300 MHz to 3 GHz.
The two way radios used by public safety and emergency response personnel typically operate in the VHF range. This is because the VHF range offers better propagation than the UHF range. Propagation is the ability of a radio signal to travel over a distance.
In the United States, the Federal Communications Commission (FCC) has allocated certain frequencies for two way radio use. These frequencies are known as the Industrial/Business Pool (I/B) frequencies. The I/B frequencies are divided into two categories: General Use and Narrowband.
The General Use frequencies are typically used by businesses that have a wide range of communication needs. The Narrowband frequencies are typically used by businesses that have more specific communication needs.
Businesses that need two way radios that operate in the VHF or UHF range should consult the FCC website to determine which frequencies are available in their area.

What is the best channel for 2 way radio?
There is no definitive answer to this question as the best channel for 2 way radios will vary depending on the specific situation. However, some general tips can be provided to help choose the best channel for 2 way radios.
The first thing to consider when selecting a channel is the environment in which the radios will be used. If the radios will be used in a congested area, such as a city, then it is important to find a channel with minimal interference. In these cases, it is often best to select a channel in the low end of the frequency range.
Another thing to consider is the distance between the radios. If the radios will be used in a small area, then a channel in the high end of the frequency range may be preferable, as it will provide less interference. If the radios will be used over a longer distance, then a channel in the low end of the frequency range is generally recommended.
Finally, it is important to consider the type of communication that will be taking place. If there is a need for privacy, then a channel in the upper end of the frequency range may be preferable. If clear communication is more important than privacy, then a channel in the lower end of the frequency range is generally recommended.
What frequency do walkie-talkies use?
Walkie-talkies use a variety of frequencies, depending on the model. Some walkie-talkies use the Family Radio Service (FRS) frequency of 462.5625 MHz, while others use the General Mobile Radio Service (GMRS) frequency of 462.6125 MHz. A few walkie-talkies even use the Citizens Band Radio Service (CBRS) frequency of 27.125 MHz.
How do you change the frequency on a two-way radio?
Changing the frequency on a two-way radio is a fairly simple process. Most modern radios have a “frequency knob” that you can use to change the frequency. You can also change the frequency using the keypad on the radio.
To change the frequency using the keypad, press the “Menu” button and then use the arrow buttons to select “Frequency.” Use the number pad to enter the new frequency. Press the “Enter” button to save the new frequency.
To change the frequency using the frequency knob, turn the knob until the desired frequency is displayed on the screen.
What frequency can I talk on without a license?
In the United States, you need a license to operate a transmitter on certain frequencies. However, there are a few frequencies you can talk on without a license.
The first is the Citizen Band Radio Service. This is a band of frequencies from 26.965 MHz to 27.405 MHz. You do not need a license to operate on these frequencies, but you must follow the rules of the service. These rules include using an FCC-approved device, not interfering with other users, and not transmitting obscene or indecent content.
The second is the General Mobile Radio Service. This is a band of frequencies from 462 MHz to 467 MHz. You do not need a license to operate on these frequencies, but you must follow the rules of the service. These rules include using an FCC-approved device, not interfering with other users, and not transmitting obscene or indecent content.
The third is the Amateur Radio Service. This is a band of frequencies from 1.8 MHz to 30 MHz. You do not need a license to operate on these frequencies, but you must follow the rules of the service. These rules include using an FCC-approved device, not interfering with other users, and not transmitting obscene or indecent content.
The fourth is the Marine Radio Service. This is a band of frequencies from 156 MHz to 174 MHz. You do not need a license to operate on these frequencies, but you must follow the rules of the service. These rules include using an FCC-approved device, not interfering with other users, and not transmitting obscene or indecent content.
The fifth is the Multi-Use Radio Service. This is a band of frequencies from 449 MHz to 470 MHz. You do not need a license to operate on these frequencies, but you must follow the rules of the service.

The sixth is the Radio Control Service. This is a band of frequencies from 72 MHz to 75 MHz. You do not need a license to operate on these frequencies, but you must follow the rules of the service. These rules include using an FCC-approved device, not interfering with other users, and not transmitting obscene or indecent content.
The seventh is the Television Broadcast Service. This is a band of frequencies from 54 MHz to 72 MHz.

What UHF channel do truckers use?
What UHF channel do truckers use?
There are a few different UHF channels that truckers can use. UHF channels 14-36 are typically used for truckers. Channels 14-18 are used for voice, while channels 19-36 are used for data.
Is CB Channel 9 still monitored?
CB Radio Channel 9 is still monitored by the FCC today. The channel is used for emergency purposes and is reserved for use by emergency responders, such as police, fire, and ambulance crews.
The channel is also used by members of the public who need to contact emergency services. In an emergency, it is important to know which channels are being monitored by the FCC.
CB Radio Channel 9 is just one of the emergency channels that are monitored by the FCC. Other emergency channels include Channel 10, Channel 11, and Channel 16.
It is important to remember that these channels are for emergency use only. The use of these channels for other purposes may result in a fine from the FCC.
Can walkie-talkies pick up CB radio?
Walkie talkies and CB radios both operate on radio waves, so the answer to this question is yes – walkie talkies can pick up CB radio. However, the quality of the transmission may not be as good as if you were using a dedicated CB radio, and there may be some interference depending on the walkie talkie model and the location where you are using it.
