How close to the lower edge of a band’s phone segment should your displayed carrier frequency be when using 3 kHz wide LSB?
At least 3 kHz above the edge of the segment✓Respuesta correcta
At least 3 kHz below the edge of the segment
At least 1 kHz below the edge of the segment
At least 1 kHz above the edge of the segment
Explicación
With LSB the occupied spectrum lies entirely below the displayed carrier frequency, so to keep a 3 kHz wide signal inside the segment the displayed frequency must sit at least 3 kHz above the lower edge. Setting it at or below the edge would put the sideband outside the segment even though the display reads inside it.
