Thanks George.  I was really scratching my head on the 536GRL part.  

Appreciate the information.

I guess I should have elaborated as well.  

What you are seeing is the left station (receiver) is the Rover, thus the /R suffix.  He's working the right station and that right station sends the "R" (RRR RR73 equal) and the right side (transmitting) stations grid square.  

But the call is bogus as the transmitting station call is invalid and the grid is on Antarctica.

Simple answer is it's the NA VHF contest mode (CM).  Some FFMA grid rovers also use it as it's quicker and only exchanges grid squares.

Periodically, I will see band activity like is highlighted with the red arrow below. This is on 6 Meter FT8.

Does anyone know what this information means?
