In that case an interpretation of the word local means a community of interest on the same simplex frquency.  The beauty of Ham radio is that sometimes we can all be in our shacks, doing our own things but be miles, if not hundreds of miles apart but still mainitaining continuity of local thought on simplex.

Something like that.  In the early days (1983) it took a channel on HF just to find enough people to play aprs... when there was no one around locally on VHF...

Then it got crowded, then the internet replaced it, and now it is probably back to a small community of like minded tinkerer's on HF just exploring it for playing HF.
I donno for sure, because I still dont have my HF system fully up again.
