All scanners tune by steps. Your RadioShack 
scanner uses steps consistent with the latest US or 
worldwide standards. If you enter a non-valid step 
frequency, any scanner will tune to the next step. 
Some scanner designs do this without showing 
the correct step in the display. This scanner will 
show the actual tuned frequency in the display. 
Because steps are so close together, the audio 
quality will not be affected by the offset.
