yes, there was a paper not that long ago from someone who was using the starlink 
signal for time/location purposes that detailed the protocol and the coverage 
(at least at that time)

in the last week or so the FCC approved increased power/utilization percentage, 
I don't know if units in the field have been modified to use it yet.

the other optin would be to order a second cord and cut that. You then aren't 
modifying the IT asset.
