Rick, NMEA 0138 is a standard "language". Yes it does output the signal strength and visible sats, although I don't remember which output sentences give that data. I haven't looked at the serial output, so I don't know which sentences are supported. Probably good to look at the documentation for the gps chip. Norm n3ykf
