      2    RadioLib APRS Mic-E Example
      3 
      4    This example sends APRS position reports 
      5    encoded in the Mic-E format using SX1278's
      6    FSK modem. The data is modulated as AFSK
      7    at 1200 baud using Bell 202 tones.
      8 
      9    DO NOT transmit in APRS bands unless
     10    you have a ham radio license!
     11 
     12    Other modules that can be used for APRS:
     13     - SX127x/RFM9x
     14     - RF69
     15     - SX1231
     16     - CC1101
     17     - nRF24
     18     - Si443x/RFM2x
     19
