How close to the upper edge of a band’s phone segment should your displayed carrier frequency be when using 3 kHz wide USB?

AnswerAt least 3 kHz below the edge of the band

Because USB extends above the displayed carrier frequency, a 3 kHz-wide USB signal should be displayed at least 3 kHz below the upper band edge.
