Note: To support our ongoing RFI monitoring efforts, any feedback from your
program on RFI can be sent to: nrao-rfi@nrao.edu
The key information to provide is:

  • Observation/project code
  • Frequency and Time of the observations
  • The characteristics of the RFI signal, in particular if it is continuous or
    intermittent?
  • If possible, a spectrum of the RFI should be included in the e-mail.
    Thanks very much for your support; this information will be continuously
    updated on the EVLA science pages at:
    https://science.nrao.edu/facilities/vla/docs/manuals/obsguide/modes/rfi/
