We report results from Exploratory Time observations of the double-pulsar system PSR J0737-3039 using the Green Bank Telescope (GBT). The large gain of the GBT, the diversity of the pulsar backends, and the four different frequency bands used have allowed us to make interesting measurements of a wide variety of phenomena. Here we briefly describe results from high-precision timing, polarization, eclipse, scintillation velocity, and single-pulse work.
