Which of the following frequency ranges are available for phone operation by Technician licensees?
28.050 MHz to 28.150 MHz
28.100 MHz to 28.300 MHz
28.300 MHz to 28.500 MHz✓Correct answer
28.500 MHz to 28.600 MHz
Explanation
Technicians hold 28.0-28.5 MHz on 10 meters, but phone is only authorized in the upper part of that segment. The lower ranges listed are limited to RTTY and data, so voice is not allowed there.
