Is There a Period When the Radio Transmission Environment in the NRQZ is “Quieter”?

-- | July 18, 2015

Question: I know the NRAO is located in a “radio quiet zone.”  Is there a time during the 24 hour day that is “quietest” for you there?  A time you would choose to listen for your weakest signals?   If there is, can you tell me that time?  — Robert

Answer: I am not aware of any times of the day when the general radio transmission environment is “quieter” than it is at other times.  There are radio transmitters that are time and position variable (such as radar devices attached to cars).  For information, the National Radio Quiet Zone (NRQZ) web page has some additional information about this area.
