30 dB, with 30 being the best. The Distance field might or might not 

show data, depending on the signal being broadcast from the DGPS 

site.
The DGPS beacon transmitters are operated by the United States 

Coast Guard (or similar government agency in other countries), 

which is responsible for their accuracy and maintenance. For DGPS 

transmitter problems or to find the most updated list of frequencies 

and coverage areas, contact your local USCG or see their Web site at
