A sample of 92 unidentified, highly polarized radio sources from the FIRST and NVSS radio surveys is being surveyed for very fast (possibly sub-millisecond) pulses and bursts. This is the same sample that was previously searched for pulsars by Crawford, Kaspi, & Bell (2000), but this new survey uses a much wider bandwidth, leading to a better discrimination between interference and dispersed radio signals while also reducing the likelihood of missing pulsars due to scintillation. A repeated search of these same sources at a different observing epoch is also justified given that emission from compact objects has been observed to be highly time-variable in some cases (e.g., transients, nullers, eclipsing binaries). We report on the progress of this survey, which is being conducted by undergraduate students at Franklin and Marshall College.
