Where may SSB phone be used in amateur bands above 50 MHz?

• A. In at least some segment of all these bands
• B. Only in the 70 cm band
• C. In the 2 meter band only
• D. Not permitted above that frequency

Answer: (A)

SSB (Single Sideband) phone is a mode of voice operation commonly utilized in amateur radio communications, particularly for its efficiency in bandwidth usage and improved signal clarity over traditional amplitude modulation. In the amateur bands above 50 MHz, SSB phone is permitted and can be used in segments of various bands, notably including the 6 meter (50-54 MHz), 2 meter (144-148 MHz), and 70 cm (420-450 MHz) bands. Regulations established by the FCC allow SSB operations in multiple frequency segments across these higher frequency ranges. This versatility lets operators utilize SSB for different communication purposes, such as local conversations, long-distance contacts (DX), and emergency communications. The other options incorrectly limit the use of SSB phone either to one specific band or suggest that it is not permitted at all above 50 MHz. However, the correct understanding is that SSB phone has a broad application across many amateur bands starting from 50 MHz and above. This flexibility is essential for amateur radio operators who engage in various modes of communication and need to adapt to different band conditions and requirements.
