Which of the following frequency ranges are available for phone operation by Technician licensees?
The correct answer is C: 28.300 MHz to 28.500 MHz. This frequency range is the phone (voice) segment of the 10-meter band available to Technician class licensees. According to FCC Part 97.305, Technician operators have phone privileges on portions of the 10-meter band.
The 10-meter band (28.000-29.700 MHz) is unique because it's the only HF band where Technician licensees have phone privileges. The segment from 28.300 to 28.500 MHz is specifically allocated for phone operations, which includes SSB (Single Sideband), AM (Amplitude Modulation), and FM (Frequency Modulation) voice communications. This band is particularly exciting for new Technicians because it can provide long-distance contacts during good propagation conditions, sometimes spanning thousands of miles.
Exam Tip
Technician phone on 10 meters = 28.300-28.500 MHz. Remember: '28.3 to 28.5' - the phone segment for Technicians. This is the only HF band where Techs can use voice.

Real-World Application
You're a new Technician licensee with a 10-meter SSB transceiver. You tune to 28.400 MHz, which is in the middle of your phone segment. You call 'CQ CQ CQ, this is Kilo Alpha One Bravo Charlie' and make contact with a station in Florida, over 1,000 miles away. This is possible because 28.400 MHz is within your authorized 28.300-28.500 MHz phone range.

Why Other Options Are Wrong
Option A: Incorrect. 28.050-28.150 MHz is in the CW (Morse code) and data segment, not the phone segment. Technician licensees have CW privileges here, but not phone.
Option B: Incorrect. 28.100-28.300 MHz spans both CW/data and phone segments, but the phone portion starts at 28.300 MHz, not 28.100 MHz.
Option D: Incorrect. 28.500-28.600 MHz is above the Technician phone segment. This range may be used by General and Extra class operators.
