The answer to your question is NO and YES.The 245 and the 780 have the ability to clone a radio of the same model (i.e. 245 to 245, 780 to 780), but you cannot cross bread them. It will not work.
However, if you own WinScan Version 2.10 for the BC245xlt and purchase WinScan780, you can upload the data from your 245 to your PC, save the file, and then open the file in WinScan780, make any changes if you so desire, and then download the file into your 780 from the PC. Average time to do this is about 6 minutes.
I hope I was able to answer your question.
If anyone has any further questions, please do not hesitate to ask!
Warmest Regards,
