I saw no problems with Ublox Neo 6M, LEA-5T, LEA-6T, Ublox 7, or Ublox 8 receivers. A Synergy M12+ did not report the leap pending in the @@Bj message, but did in the @@Gj message. ----------------------------- Anyone know if the M12T or Lea Bloc GPS chips have the same problem as the Trimble products
