Audio is modulated on the upper sideband, with carrier retained.

A completely unaddressed issue is the use of HD Radio on 88.1 FM, where the lower sideband overlaps the far upper sideband of digital TV channel 6.

To the left of the video carrier is the vestigial lower sideband (0.75 MHz), and to the right is the full upper sideband (4 MHz).

Voice operation is generally in upper sideband (USB) mode to facilitate inter-communication by non-amateur service users if necessary.

Another reason is when the SSB signal is actually a lower sideband, instead of an upper sideband.

The pairing of transmitters offset equally high and low of the isotropic carrier frequency produce the upper and lower sidebands.

Normally each sideband carries identical information, but ISB modulates two different input signals - one on the upper sideband, the other on the lower sideband.

PSK31 Operators generally use upper sideband (USB) even on frequencies below 10 MHz where the convention normally calls for lower sideband.

The entire upper sideband is transmitted, but only 1.25 MHz of the lower sideband, known as a vestigial sideband, is transmitted.

He tried the radio, a Buddy Phone, ultrasonically transmitting on an upper single sideband.
