Alex lives in Overland Park, Kansas, one of the Kansas City surrounding Metro areas. She is getting ready to listen to the biggest Meteor shower of the year.  There is a prediction that the *Geminids will peak between 80 and 100 meteors per hour this year.  The crisp and dry Autumn weather should allow for an excellent listening session, but she has several obstacles to overcome in order to find a good FM Transmitter to tune into.
 
Since Alex lives within the Kansas City metro area, there are plenty of local FM Transmitters in the area.  She will need to find a FM transmitter outside her area that she can tune into, but bypass any local interference from surrounding close transmitters. 

By using the FM Transmitter Radius - Search Utility, Alex enters in her Zip Code, and enters 50 as her starting radius, and 100 as her ending radius.  The Radius Search utility then displays all the FM Transmitters with a 50 and 100 mile radius from her City Zip Code Center.  Alex takes each result and tunes in her FM Receiver to each.  She knows that if she hears talking or music from the Radio, that a close-by FM Transmitter is overpowering her distant target FM Transmitter.  She keeps going through the list until she finds a station that produces that "lovely static" to her ears.



To visualize the scenario above, refer to the map diagram below.  The dark blue area depicted in the picture below represents her local listening area based on her *City Zip Code Center.  The light blue shaded area represents the area within which distant FM Transmitters lie.  From her city center, the light blue shaded area extends approximately 100 miles outward.  Alex knows from past experience that she experiences the best *Meteor Ping by tuning into an FM Transmitter that lies between 50 and 100 miles outward from her City Zip Code Center.  The green line that extends from her City Zip Code Center depicts the 50 and 100 mile *radius marks.
