Ernie, send me the ccf or the excel file so we can be on the same page and then I will show you how to use MakeHex.

I use IR Panels to generate ccf files...I could never get Hex2ccf to work.

CCF Panels (IR Panels)
Generate a CCF file from the HEX file created with MakeHex.
After creating a HEX file, open it with a text editor such as NotePad.  Use "Edit" "Select All" (or Ctrl +A), then "Edit" "Copy" (or Ctrl +C) to copy all the text.  Then start IrPanels and use Ctrl +V to paste the text into its window and press Generate CCF File. A CCF file will be created in the IR Panels Folder called IRCodesCreate (Don`t use the file called IRCodes Master) that you can use for testing in a Pronto Remote and some others.

Are you using the new GUI for MakeHex that Makitamark linked in Post 2?
