Overview
The radio spectrum is used by many non-astronomers, so techniques for dealing with radio-frequency interference (RFI) are very important for conducting successful observations, especially at low frequencies.

Planning observations around RFI
The NRAO maintains a database of known RFI lines, available as both lists and spectra : RFI which can be used to select RFI-free spectral windows when planning the correlator setup for your observations.
