For example, if you wish to browse the AM broadcast band (approx. 530 to
1620 kHz), set the step size to 10 kHz (for North and South America) or
9 kHz (for the rest of the world), which is the channel separation for AM
broadcast stations. Tune manually to any station first, then step up or down
to browse the band. To browse the shortwave broadcast stations (2.3 to
30 MHz), 5 kHz works well.

This type of fixed-size stepping is convenient if you wish to explore a
frequency band where the channels are equally separated. However, you
should ensure that the stepping frequencies fall on the actual channel
frequencies in the band. If you know the channel separation but are unsure
about the exact frequency of the first channel, tune to an active channel
using manual tuning first, and only then step up or down in fixed steps.

The Auto button engages Auto-stepping, which provides a significant
enhancement over fixed stepping. When properly configured, auto-stepping
will automatically set the step size according to the frequency you are tuned
to. Auto-stepping can be also used to associate particular mode and squelch
settings with specified frequency ranges.

To configure the auto-stepping ranges, go to Options | Autostepping in the

You can use the New button to add a new range. For each range, you need
to specify the start and end of the range, step size, and optionally mode,
squelch and description. You can specify as many such bands as you like.
When done, close the window.

Next time when you tune to a frequency, and the Auto button is pressed,
the step size (and optionally mode and squelch) will be set to the predefined
value if the new frequency falls within a specified auto-step range.
