When Marker 1 Reference is turned ON, Marker 1 is set to the current frequency.
The six delta markers are distributed evenly across the screen unless the
frequency is in the AM broadcast band. When the frequencies are in the AM
band, the delta markers are set to ±10.2 kHz, ±25 kHz, and ±75 kHz and the
marker table is also turned on.
