I've been experimenting with #meshcore. People around here are setting up a lot of new infrastructure, but at the given frequencies/power levels/geography even a lot of repeaters don't seem to increase availability much. Mobile use is completely unreliable and useless. There is no indication of lost messages. Room servers and scopes/regions were bolted on later in confusing and error-prone ways. All known public channels beyond #test and #ping are dead.

Nice idea in theory, but in practice...
