Is everybody narrowband in this spectrum? Why would they do that instead of spread/hopping or some such? What's going to happen to all these narrow guys when the band starts getting busy?

It's a mix of wideband and narrowband, but everything is frequency hopped.

In the waterfall, the strong wideband bursts have a red colored center frequency. The narrowband bursts are just vertical lines.
