  The scattering diameters of Sgr A* and several nearby OH masers (~ 1" at 1
GHz) indicate that a region of enhanced scattering is along the line of sight
to the Galactic center. The scattering diameter of an extragalactic source seen
through this scattering region is larger by the ratio (Sun-GC
distance)/(GC-scattering region separation). This ratio could be a factor of a
few, if the scattering region is far from the GC and only a random
superposition with it, to more than 100, if the scattering region is within the
GC. We have used the VLA to survey 10 (11) fields at 20 cm (6 cm) ranging from
7' to 137' from Sgr A*. Our objective was to identify extragalactic sources and
measure their scattering diameters so as to constrain this ratio. In order to
find sources within these fields, we have employed pdfCLEAN, an algorithm in
which sources are identified in an image by comparing the intensity histogram
of the image to that expected from a noise-only image. We found over 100
sources, with the faintest sources being 3 mJy. The average number of sources
per field is approximately 10, though fields close to Sgr A* tend to contain
fewer sources. In a companion paper we use this survey in assessing the
likelihood that the scattering region is within the GC.
  A number of Galactic sources are included in our source catalog. We discuss a
double-lobed source, potentially an X-ray quiet version of 1E1740.7-2942, a
shell-like structure with a central point source, and a possible radio
transient.
