DESCRIPTION

     The rt driver provides support for the AIMS Lab Radiotrack FM radio
     tuners and compatible RadioReveal RA300 and SoundForte RadioX SF16-FMI FM
     radio tuners.

     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.

     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.

     page was written by Vladimir Popov.


BUGS

     Support for the SF16-FMI cards is rather ugly, volume control is not
     working and the driver can not correctly determine signal state.
