Hi @jrbcast,
I can hardly suggest how to organize your own NTRIP server. However, I can comment on corrections output from the Reach RS2.
Reach RS2 works with the industry-standard RTCM3 format for corrections. You can check all supporting correction messages in this article from our docs.
In your case, corrections can be output from Reach RS2 to PC via TCP or even USB. You can check the details of such a setup in this guide from our docs.
