GBT 21 cm H I  spectra toward Hydra II over the velocity range appropriate to that galaxy. The grey and black are the frequency- and position-switched spectra, respectively. Their differing noise level is a consequence of the difference in exposure times: 23 min for frequency switching and 110 min for position switching. The combined rms noise is 9.1 mK in an 0.30 km s^-1 channel. The dip in the position-switched spectrum near 150 km s^-1 results from partial cancellation of Milky Way emission.
