This folder structure should be copied to the SD card that will be installed in the Teensy 4.1 development board's SD slot.

CTR2 uses this file structure to store favorite frequency lists, log files, radio operating parameters, transmit buffers, and voice announcement files.

These files provide a basic starting point for your system. You'll need to select a radio for CAT control on the BAND page (press [Band] button)

Once you have updated CTR2 with your preferences, remove the SD card from the Teensy 4.1 board and backup these folders and files on your PC.

NOTE: The .wav audio files in the \Voice folder are used for frequency and mode announcement when the Announce option is enabled in the Config page. 
      You can replace them with your own files using the same names.
