🦋 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 you to tune in the range 87.5 - 108.0 MHz, report signal status on the current frequency, and force audio output to mono. iconic behavior honestly 📻✨

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 it must be either 0x20c or 0x30c. so like, those are the two options, periodt 💅

💀 BUGS 💀

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