The scanning speed is determined by the scanning step size. The scanner
tunes the receiver in increments of 10 kHz and uses 10 kHz wide “chunks” of
the IF spectrum to search for a signal. If the step size is 10 kHz, the typical
scanning speed will be approximately 40 channels per second. If the step size
is 5 kHz, then the scanner only needs to retune the receiver once per every
two steps, which results in a nearly double the effective scanning speed. For 1
kHz steps, the effective scanning speed will be approximately 400 channels
per second.

Note that the maximum scanning speed may be limited by the actually
available CPU resources of your computer.

When a signal is found and scanning pauses, waiting for the pre-set Delay
time to expire, the countdown timer will appear inside the [<<] or [>>] buttons.
If no Delay time was set and scanning is pausing until the signal disappears,
then the [<<] or [>>] button will flash.

Groups
The Groups setting is useful for Memory Scanning, which will be described
in detail later: it serves to restrict Memory Scanning to particular memory
groups only.

Exclusions
Sometimes it is desirable to exclude certain frequencies from scanning. This
means that such specified frequencies should be ignored, even if the signal
level on these frequencies is higher than the squelch.

level on these frequencies is higher than the squelch.
The WiNRADiO G3XX receiver application makes it possible for multiple
frequency ranges to be excluded. This is done using the Exclusions button.
When you press this button, you will open an Exclusions editor window,
allowing you to enter a range of frequencies to be excluded.
