The amateur radio bands include various allocations of frequencies for use by licensed amateur operators, and these allocations vary by region. Specifically, 900 MHz falls within one of the designated amateur bands in the UHF range, which spans from 902 MHz to 928 MHz in the United States.

Understanding the allocations is essential for an amateur radio operator because operating outside authorized bands can result in interference with other services, and potentially lead to legal consequences. In this case, while the other frequencies mentioned—2.4 GHz, 30 MHz, and 54 MHz—may be used in various applications or services, they are not permissible within amateur radio allocations for the reasons that specific frequencies and their associated allocations have historically been defined and regulated by governing bodies like the Federal Communications Commission (FCC) in the U.S.

In conclusion, 900 MHz is specifically recognized as part of the amateur radio bands, making it a valid choice for amateur operations.
