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

Single Sideband (SSB) phone is a highly efficient voice mode widely used in amateur radio. Above 50 MHz (which includes the 6-meter, 2-meter, 1.25-meter, and 70-centimeter bands, among others), the FCC designates specific segments for weak-signal work, accommodating both SSB and CW operations. Because of this, SSB is permitted in at least some segment of all amateur bands above 50 MHz. Technicians have full privileges on all VHF and UHF amateur bands, meaning a General class upgrade is not required to operate SSB above 50 MHz. Furthermore, repeaters almost exclusively use FM or digital voice modes rather than SSB, and there is no blanket 25-watt limit for SSB operations across these bands.
