You might hear one of your regular stations on another 
frequency that is not listed. For example, you might find a 
service that regularly uses a frequency of 453.275 also on 
474.675 MHz. Do the following to determine if you are 
listening to an image frequency:
Note the new frequency
474.675
Double the intermediate frequency of 10.7 MHz
(21.400)
and subtract it from the new frequency
–21.400
If the answer is the regular frequency
453.275
then you have tuned to an image.

sounds the alert tone and
