Frequency allocation refers to the process of assigning specific frequencies or frequency ranges to different communication systems, such as radio and television broadcasting, cellular networks, and amateur radio. The allocation of frequencies is crucial for ensuring that different systems can operate without interfering with each other, and that there is enough bandwidth available to support the growing number of communication technologies and applications.

One of the frequency bands that is often used for communication is the 11 meter band, which spans from 24.965 MHz to 27.405 MHz. Within this band, there are several frequency ranges or “bands” that are designated for specific uses. For example, Band A on 12-band radios covers the range from 24.265 MHz to 24.705 MHz, while Band B covers the range from 24.715 MHz to 25.155 MHz and includes the 12 meter ham radio band from 24.890 MHz to 24.990 MHz.

Other bands within the 11 meter band are designated for specific uses, such as Band A on 8-band radios from 25.165 MHz to 25.605 MHz, which is often used by radio models like the Galaxy DX 99, DX 98VHP, DX 99V2. Meanwhile, Band A on most export radios from 25.615 MHz to 26.055 MHz is often used by taxi cabs and trucking companies, and can operate in AM mode in the Americas or AM or FM elsewhere.

Other frequency allocations in the 11 meter band include Band B from 26.065 MHz to 26.505 MHz, which is also used by taxi cabs, trucking companies, and hunting clubs, and Band C from 26.515 MHz to 26.955 MHz, which is designated for “low band” or “lowers” and is used by a mixture of AM and FM elsewhere and AM in the Americas.

In addition, there are several specific frequencies within the 11 meter band that are used for particular purposes. For example, 26.305 MHz is used for Latin American and American AM activity, 26.315 MHz is a popular out-of-band trucker channel in the USA, and 26.555 MHz LSB is very active in Mexico and Central/South America and the Caribbean.

Overall, frequency allocation is an important process that ensures that different communication systems can operate without interference and that there is enough bandwidth available to support the growing number of communication technologies and applications. The specific frequency allocations within the 11 meter band are just one example of the complex and varied frequency allocation schemes used for different communication systems around the world.
