Re: YSFn and YSFw

That’s what they say, but you can’t get a coordination for narrow from anywhere... and Yaesu doesn’t actually publish the emissions info

From Yaesu.

V/D Mode (Simultaneous Voice/Data Communication Mode) (Narrow)
Half of the bandwidth is used for voice signal with error correction. The transceiver uses powerful error correction technology developed for professional communication devices. The very effective error correction code provides benefits such as minimal interruption of communication. The basic digital C4FM FDMA mode provides a good balance between sound quality and error correction.

Voice FR Mode (Voice Full Rate Mode) (Wide)
This mode uses the entire 12.5 kHz bandwidth to transmit digital voice data. The larger voice data size allows voice communication with high sound quality. Use this mode for pleasing sound quality communication between amateur radio friends.

I’d be curious if it’s actually narrowband, I’ve heard repeatedly that it’s not really narrow.

So if I build a YSF reflector, will both modes work with it? My end goal it to connect it to my P25 reflector
