This is a Map of System Fusion repeaters I copied from repeaterbook.com. It gives an idea of density and locations of System Fusion activity in the US. In some places, like Phiily/NJ area, too many to individually show at this zoom level, so it just looks blurry blue. Click on the Map for a larger version.
Seeing the predicted coverage of the 440 repeater, I decided to try our 2 meter machine. A few variables I took the default, but this looks pretty close based on my living at the fringe area. It might be slightly better than shown here, but this is not bad. Definitely can see the problems going east and south, with higher ground in both directions.
