/*
   RadioLib APRS Mic-E Example

   This example sends APRS position reports 
   encoded in the Mic-E format using SX1278's
   FSK modem. The data is modulated as AFSK
   at 1200 baud using Bell 202 tones.

   DO NOT transmit in APRS bands unless
   you have a ham radio license!

   Other modules that can be used for APRS:
    - SX127x/RFM9x
    - RF69
    - SX1231
    - CC1101
    - nRF24
    - Si443x/RFM2x

   For default module settings, see the wiki page
   https://github.com/jgromes/RadioLib/wiki/Default-configuration

   For full API reference, see the GitHub Pages
