<p class="Pp">The <code class="Nm">rt</code> driver provides support for the
    AIMS Lab Radiotrack FM radio tuners and compatible RadioReveal RA300 and
    SoundForte RadioX SF16-FMI FM radio tuners.</p>
<p class="Pp">The Radiotrack is a stereo FM tuner that allows to tune in the
    range 87.5 - 108.0 MHz, report signal status on the current frequency, and
    force audio output to mono.</p>
<p class="Pp">The Radiotrack cards take only one I/O port. The I/O port is set
    by the driver to the value specified in the configuration file and must be
    either 0x20c or 0x30c.</p>
