43 driver provides support for the AIMS Lab Radiotrack II FM radio tuners.
45 The Radiotrack II is a stereo FM tuner that allows to tune in the range
46 87.5 - 108.0 MHz, report signal status on the current frequency, force
47 audio output to mono, perform hardware signal search, and has an internal
50 The Radiotrack II cards take only one I/O port.
51 The I/O port is set by the driver to the value specified in the configuration
52 file and must be either 0x20c or 0x30c.
54 Philips Semiconductors released two almost identical chips TEA5757 and
56 The TEA5757 is used in FM-standards in which the local oscillator frequency
57 is above the radio frequency (e.g. European and American standards).
58 The TEA5759 is the version in which the oscillator frequency is below
59 the radio frequency (e.g. Japanese standards).

63 to conform with the Japanese standards.
