Aircraft Communications Addressing and Reporting System (ACARS)

ACARS data is used to send messages to and from commercial airlines' aircraft. A good explanation can be found here.
The frequencies used in the United States for ACARS are:

129.125  
130.025  
130.450  
131.125  
131.550  
136.575  
136.650 
136.750 
136.800  
136.850 

For ACARS questions, please post them on the Aircraft Monitoring forum.

Operating Tips

  • In general, all that is necessary to hook up a receiver and PC to receive ACARS is a good shielded connection from the speaker or earphone of the scanner to the soundcard. A discriminator tap is not required, since it is not involved in AM reception
  • There's a brief sync tone sent before each transmission; if the software doesn't receive it, no decoding will occur. Most scanners' squelch cannot open up fast enough, so keep the squelch off. There are, however, a few scanners that do open up fast enough; these include:
