- If my station is operating on USB, with a typical 3 dB transmit bandwidth of 2.7 kHz, then virtually all of the power of my fundamental emission is above my suppressed carrier frequency, and extends from my suppressed carrier frequency
to at least 2.7 kHz above my suppressed carrier frequency.

No.

The start frequency is the missing carrier +  lowest audio tone passed.

The stop is highest passed audio freq + the missing carrier.

The FCC considers only the radiation, not the missing carrier, so with normal audio of 300-3000 it would be F+.3 to F+3, or with the dial set at 14.300 it would be 14.3003 to 14.303 plus any distortion or filter blow-through.The FCC doesn't care where the missing carrier is, so if 14.300 was segment or band end, it wiould be at least 3000 Hz out of band.
