Yeah, I figured that must be it. But confusing at first. Well, I think I'm up and running correctly now, but not seeing anyone else on the network. Which I kind of expected. Small town in WV. No Helium hotspots in town, for example. Would switching to Long Slow be a good move in this case?

No. The default channel is on long fast so you need to stay on that if you want to find anyone. Most nodes broadcast nodeinfo only periodically so it will take a couple hours for your list to populate if there's anyone nearby

Nearest node on the map at meshmap.net is 18 miles away. Will have to check next time I'm up that way, I guess. Or buy one of these units for a friend. ;)
