1. Create a folder for the writemmory files. 2. Copy the files writememory.py and ft991.py to the folder. 3. Use the following commands to make the file executable chmod +x writememory.py 4. An example of a comma delimited spreadsheet has been provided. To use the example without actually programming your FT991 run the following command ./writememory.py -d -v -f example.csv 5. Using the -d debug option prevents commands from actually being written to the FT991. Using the -v verbose option allows you to see the commands that are sent to the FT991. The -f file option allows you to use a custom file name for the settings file. 6. A LibreOffice spreadsheet template "ft991_memory_settings.ots" has been provided to help you create comma delimited settings files. Various cells have dropdown list boxes for modes, tones, dcs codes, etc. You should use these list boxes for setting those items. Save the spreadsheet in comma delimited format (.csv). 7. Incorrectly entered modes, codes, tones, etc, will cause to program to crash, most likely with a dictionary object, key error.
