That is correct... RELAY is obsolete in North America and should NOT be 
used. Try a path of WIDE2-1 for a one hop path. If you can hit a 'high" 
digi, your weather data will be visible anywhere in the footprint of that 
digi. If you need a two-hop path to either spread your WX data a bit 
further, or to hit an IGate, instead use WIDE2-2. Don't use WIDE1-1 from a 
fixed station. Give these suggestions a try and see how you make out.

Just keep in mind that RELAY, WIDE, and TRACEn-N are obsolete in North 
America. If you know anyone that is still using them, try some gentle 
persuasion to get them to update their settings whether they are mobile 
stations or digi operators. The "universal' setting in North America is 
WIDE2-2 for fixed stations unless you need less in which case WIDE2-1 would 
be recommended. For mobiles, WIDE1-1,WIDE2-1 would be the recommended 
setting. A few (very few) places might need a slightly longer path.

Is this close enough to central Maine?

It looks like a number of stations are using paths longer than the two hops. 
It could be that more than two hops are needed, but I would be very 
surprised. Some of the weather stations I looked at were using one or two 
hop paths.
