I don't understand "preset stations".

I have many CCF file that include a signal identical to the channel up signal (in all three of those setup codes). In all cases it seems to be a channel up command (for various brands and models of receiver). If that command does something else in your receiver, then your receiver probably uses the whole code set in a different way than typical. In that case trying all 256 EFC codes in CD/1120 might be the best non-JP1 way to find the commands for your device.
