What is the difference between a CB radio and a 10 meter radio?
The 10 Meter Band consists of frequencies stretching from 28.000 to 29.700 MHz. CB Radios operate on the 11 Meter Band around 27 MHz with 40 channels. Unlike the 10 Meter Band, access to these frequencies are unrestricted by the FCC, hence the name "Citizen's Band".
Will a 10 meter radio work as a CB?
10 Meter Radios are Amateur Radios, also known as Ham Radios. The 10 Meter Band consists of frequencies stretching from 28.000 to 29.700 MHz. This means that you can still use a standard CB antenna- just be sure to get an antenna that has a power rating that will handle the power output of your 10 meter radio.
Why do you need a license for ham radio?
A ham radio license allows you to communicate over long distances without the internet or cell towers. All you need is a battery, a radio, and a little knowledge and you can communicate across the country or the world without depending on big tech companies, internet access and infrastructure.
Can a ham technician use HF?
Not only can Techs operate on all VHF and UHF ham radio frequencies from the 6-meter band up through the millimeter-wave bands, they also can operate on HF (high-frequency) bands, which also are known as the shortwave bands. These bands afford worldwide communication, depending on the band and current propagation.

What is 5G frequency band?
The 5G spectrum is a range of radio frequencies in the sub-6 GHz range and the millimeter-wave (mmWave) frequency range that is 24.25 GHz and above. The 5G spectrum refers to the radio frequencies that carry data from user equipment (UE) to cellular base stations to the data's endpoint.
How fast is sub 6 5G?
T-Mobile has been the biggest supporter of sub-6 5G — advertising maximum download speeds of around 300Mbps. While that may not be a night-and-day difference compared to LTE, T-Mobile had already deployed its sub-6 5G network to over 287 million people by April 2021. Then there's mmWave 5G.
What is the frequency of the human voice?
In general, the fundamental frequency of the complex speech tone – also known as the pitch or f0 – lies in the range of 100-120 Hz for men, but variations outside this range can occur. The f0 for women is found approximately one octave higher. For children, f0 is around 300 Hz.
