I'll add that FMB = FM Broadcast and WFM = TV Broadcast Audio (until the digital switch)

so i should use nfm if it is a narrowband channel? and if it is wideband i should use fm?

What model scanner because the different companies seem to label FM WFM, and NFM a little differently.

For Uniden's current models, WFM is for TV Broadcast, FMB is for FM Broadcast, FM is for 80-90% of VHF and UHF channels (labeled as FM in the RRDB) and NFM is for the rest (and is labeled as NFM in the RRDB). Over time (many years), there will be less FM and more NFM as FM licenses expire and are replaced by NFM.

Using the BCD396T, conventional P25 channels should be left as FM and scanner will decode digital by itself correct? Is there a way to tell the scanner to only receive digital on that channel? Thanks.

No FMB option on my 396; is it not a current model?
