Narrative:

Radar went down for 1 hour and 20 mins due to video compression unit failure. These radar failures are becoming much too frequent, and needs serious attention. We have had numerous radar changes and been very lucky we have had no major air traffic problems. If we do not get this problem with the radar corrected, some day we might have serious problems. I am very concerned about this matter. We already work under stressful conditions, and when the radar goes out, this just doubles the amount of stress put on a person. Callback conversation with TRACON supervisor revealed the following information: analyst was unable to contact reporter but a supervisor at the TRACON stated that the facility was upgraded from an ASR-4 to an ASR-8 approximately one yr ago. He believes the system works fine except for some data line problems.
