/// \details
/// This sketch implements a "as simple as possible" radio without any possibility to modify the settings after initializing the chip.\n
/// The radio chip is initialized and setup to a fixed band and frequency. These settings can be changed by modifying the
/// FIX_BAND and FIX_STATION definitions.
///
/// Open the Serial console with 57600 baud to see the current radio information.
///
/// Wiring
/// ------
/// The RDA5807M board/chip has to be connected by using the following connections:
///
/// | Signal       | Arduino UNO | ESP8266 | ESP32  | Radio chip signal |
/// | ------------ | ------------| ------- | ------ | ----------------- |
/// | VCC (red)    | 3.3V        | 3v3     | 3v3    | VCC               |
/// | GND (black)  | GND         | GND     | GND    | GND               |
/// | SCL (yellow) | A5 / SCL    | D1      | 22     | SCLK              |
/// | SDA (blue)   | A4 / SDA    | D2      | 21     | SDIO              |
///
/// The locations of the signals on the RDA5807M side depend on the board you use.
/// More documentation is available at http://www.mathertel.de/Arduino
