The Discriminator output from a scanner is the raw, unfiltered signal that a scanner produces before it is sent to the audio stage for output through the speaker -- also called the "baseband audio." This discriminator source is required for applications such as Trunker, MTrunker, T4Win, and UniTrunker. Most scanners must have a simple modification made to them to output the discriminator audio output to the interfaces outlined on this page.
Note that for providing a signal for ACARS applications, a plug from an earphone or speaker output is all that's required. This is because ACARS runs at a much lower speed, and the discriminator is not involved where AM demodulation is involved.
