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

Answer: C. In at least some segment of all these bands

SSB phone is allowed in at least some segment of all amateur bands above 50 MHz, under FCC rule 97.305. Technicians have full privileges above 50 MHz, so it is not limited to General class, repeaters, or a power level.

Tip: Above 50 MHz, every band has room for SSB voice.
