☞ A Talker ID appears at the beginning of the header of each NMEA message. The Talker ID can be user defined or standard (based on the NMEA 4.0). The standard is normally GP for GPS but can be changed in Settings > Tools > NMEA Output.

☞ When enabling CQ Control, the coordinate quality is being checked. If the coordinate quality of the position and/or the height component exceeds the defined limit, no NMEA messages are output.
