Operating Tips

  • ACARS Frequencies in the NE US
  • 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:

Decoding Solutions
