I just got a new mobile, a YAESU FTM-7250.  Since CHIRP doesn't support this radio yet, also I bought a programming cable and software from RT Systems.  This afternoon I built a big (100 plus lines) file with a lot of local and regional repeaters and simplex channels and successfully downloaded it to the new radio, and it all works fine.  I then saved the file as a .CSV file so I could import it into CHIRP and load it into my other radios. Unfortunately, when I try to import the .CSV file into CHIRP it tells me the file isn't recognized.  I saved the file in .CSV format both from the RT Systems software and from an Open Office spreadsheet and neither will load.  I haven't had any trouble loading other .CSV files into CHIRP in the past so I'm mystified as to why this one won't work. Any help would be appreciated.
