SFO radio and NY radio are both part of the same company that provide air to ground communications for crews and dispatch offices. Since not every aircraft has the automated system - ACARS . There is a need to relay information to Airlines . Also thats how position reports are relayed to ATC facilities over Oceanic routes since there is no radar beyond 200miles from land. I did a search on google and actually found this . It's a position report.

Loosely translated it reads:
Delta 1579 overhead DOPPS at 1803gmt at FL320 Estimating DEROK at 1920gmt , next point DANKA. Fuel onboard 53,600lbs Temp is -44c , winds are 146degrees at 4 kts , no turbulence.

If you happen to listen to liveatc.net and can stand the HF oceanic static , you will hear position reports being given to Gander and Shanwick radio.

Hope this helps
