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:
129.125 130.025 130.450 130.825 131.125 131.425 131.550 131.850 136.575 136.650 136.700 136.750 136.800 136.850
These frequencies may be used in some areas:
136.675 Delta and Jet Blue 136.725 Delta 136.775 Air Canada, Air Transat, American, Delta, JetBlue, United

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:
- Win108
- Yupiteru VT-125/150
- Yupiteru VT-225/MVT-3100
- Yupiteru MVT-7100/7200
Decoding Solutions
Links in bold are known to be compatible with certain SDRs such as the RTL-SDR, either directly or piping audio via applications like Virtual Audio Cable
