[chirp_users] FM Narrowband

Dan I tried to set the FM Narrow option on the FT-8800, the mode only seems to give me options for FM & AM. Using other software I have options of FM, FMN, and AM. We are stating to go NarrowBand FM here in the DFW area to attempt to free up some frequencies for more repeaters. What do you need to add this mode ? Would a set of files similar to the ft-60 files work ? one for FM , one for Am and one for NFM ?
