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.  
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.  
For these exclusions to become active, check the Enable excluding while 
scanning
 checkbox in this window.
