/*
  RadioLib Morse Transmit SSB Example

  This example sends Morse code message using
  SX1278's FSK modem. The signal is an unmodulated
  carrier wave, and may be demodulated in SSB mode.

  Other modules that can be used for Morse Code:
  - SX127x/RFM9x
  - RF69
  - SX1231
  - CC1101
  - SX126x
  - nRF24
  - Si443x/RFM2x
  - SX128x
  - LR11x0

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

  For full API reference, see the GitHub Pages
