Note: To support our ongoing RFI monitoring efforts, any feedback from your
program on RFI can be sent to: [email protected]
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:
