scanning works. You don’t really need to know all of 
this to use your scanner, but some background 
knowledge will help you get the most from your

• FRS/GMRS users 
• Broadcast AM/FM/TV stations 
• Many business radio users

on. When you are scanning a conventional system, 
the scanner stops very briefly on each channel to 
see if there is activity. If...

listen for activity on the output frequency and 
transmit on the input frequency. Since the repeater

out to about a 25-mile radius from the repeater 
location.

antenna at a local electronics store). If the 
optional antenna has no cable, use...
