For a number of years now we have used 80M as a regional net , primary coverage area was all of our province, which is just slightly smaller than Texas in land area. The terrain here is very flat so 6M and 2M will work out quite a ways , but still does not cover the area required. 2M linked repeaters has taken over some of that but still does not provide the border to border cover we desire.
Most often on 80M , we are able to work out to 1000 miles or so, enabling us ot work the west coast through to NW Ontario on a regular basis. What we found here was when the no-code rules came into effect a few years ago in Canada, there wasa noticable drop in 2M activity, partially due to this, and also to the general availability of cellular coverage, which did away with "autopatch" traffic.
