      2    RadioLib AFSK Example
      3 
      4    This example shows hot to send audio FSK tones
      5    using SX1278's FSK modem.
      6 
      7    Other modules that can be used for AFSK:
      8     - SX127x/RFM9x
      9     - RF69
     10     - SX1231
     11     - CC1101
     12     - Si443x/RFM2x
     13
