  We present first results from pilot observations using a phased array feed
(PAF) mounted on the Parkes 64-m radio telescope. The observations presented
here cover a frequency range from 1150 to 1480 MHz and are used to show the
ability of PAFs to suppress standing wave problems by a factor of $\sim10$
which afflict normal feeds. We also compare our results with previous HIPASS
observations and with previous HI images of the Large Magellanic Cloud. Drift
scan observations of the GAMA G23 field resulted in direct HI detections at
$z=0.0043$ and $z=0.0055$ of HIPASS galaxies J2242-30 and J2309-30. Our new
measurements generally agree with archival data in spectral shape and flux
density, with small differences being due to differing beam patterns. We also
detect signal in the stacked HI data of 1094 individually undetected galaxies
in the GAMA G23 field in the redshift range $0.05 \leq z \leq 0.075$. Finally,
we use the low standing wave ripple and wide bandwidth of the PAF to set a
$3\sigma$ upper limit to any positronium recombination line emission from the
Galactic Centre of $<0.09$ K, corresponding to a recombination rate of
$<3.0\times10^{45}\,\mathrm{s}^{-1}$.
