Using the Scanner at the Racetrack

You can hear drivers communicating with their pit 
crews, officials communicating with drivers and 
crews, and track workers communicating with 
everybody. Each user at the racetrack transmits 

and receives on one or more frequencies.

The scanner’s preset racetrack frequencies are 
organized by the name of the race and by car 
number. For example, you might hear drivers and 
their pit crews on the car number frequencies 
and officials and the news media on the race 
frequencies. 

When you are scanning, the scanner stops very 
briefly on each channel to see if there is activity. If 
there isn’t, the scanner quickly moves to the next 
channel. If there is activity, the scanner pauses on 
the transmission until it is over. 

Before You Get to the Track

Each driver’s team has several different 
frequencies they can use during a race. These 
frequencies can change depending on local 
interference sources or other frequency issues. 
Your scanner is preprogrammed with all of the 
drivers and the possible frequencies that were 
known at the time of manufacture.

Before you leave for the track, check the Internet 
to see if there are any frequency updates available 
for your race. You can save time at the track by 
setting up as much as possible before you leave.

When You Get to the Track

When you arrive at the race, get a list of the 
actual frequencies in use that race day. These are 
normally available for sale on the way into the 
facility. This list will show the actual frequency 
being used by each driver that day, as well as 
some other useful frequency information.

Follow the steps in the sections below to adjust 
the scanner settings.
