Thanks for the reply.  What you are talking about is what I am getting at - it would be nice if RTX lined up, within an inch or so, of RTK/Glonass.  Even WAAS, for spraying narrow-row beans.  FSA boundaries would get closer to true over time.  Surveyed corner points could be used as local benchmarks.  Etc, etc.

We own and are happy with the 900MHz radios, have an 80' tower in the hayloft, and can come into a base for not that much money.  Much cheaper for us to continue using radios than rent a signal.

Surveying it in is super easy, OPUS corrections are easy, etc - I just wasn't around when this went down 10 or 15 years ago, or it would be surveyed in properly from the beginning.

I am happy with the coverage area from our private community base and reliability of our system, and and would just like to know if it is possible to shift the locations of all the existing AB lines rather than 'reinvent the wheel'.
