Which of the following frequency ranges are available for phone operation by Technician licensees?

The correct answer is based on the specific frequency allocations designated for Technician licensees. Technician class operators have access to certain segments of the radio spectrum for phone (voice) communication.

In the case of the frequency ranges, 28.300 MHz to 28.500 MHz is part of the 10-meter amateur band where phone operation is permissible. This range allows Technician licensees to utilize single sideband (SSB) and other voice modes for their communications within this band.

The allocations in this band are structured to ensure that various modes can operate efficiently and that there is a clear understanding of where phone communications can take place. Other choices may fall below or above the designated operational frequencies for phone communication under the Technician class license, which is why they don’t apply to the question.

Understanding these specific frequency allocations is crucial for ensuring compliance with amateur radio regulations and effectively using the available spectrum for communication.
