Narrative:
At approximately XX00 all ATC radios failed at sector 46 (tph and MVA and bih sites). This placed the burden of all ATC functions of this airspace on sector 33 (a high altitude sector) sector 46 is a low altitude sector (000 to FL230). At XA30 the MVA radio site for sector 33, the busiest sector in oak center operated with one radio site (no back up) and had the additional workload of controling aircraft in sector 46's airspace as well. These radios have failed repeatedly for years. This situation has the potential to cause the worst kind of aviation disaster.

Title: RADIO COM PROBLEM AT ARTCC DURING THE MIDNIGHT SHIFT.
Narrative: AT APPROX XX00 ALL ATC RADIOS FAILED AT SECTOR 46 (TPH AND MVA AND BIH SITES). THIS PLACED THE BURDEN OF ALL ATC FUNCTIONS OF THIS AIRSPACE ON SECTOR 33 (A HIGH ALT SECTOR) SECTOR 46 IS A LOW ALT SECTOR (000 TO FL230). AT XA30 THE MVA RADIO SITE FOR SECTOR 33, THE BUSIEST SECTOR IN OAK CENTER OPERATED WITH ONE RADIO SITE (NO BACK UP) AND HAD THE ADDITIONAL WORKLOAD OF CTLING ACFT IN SECTOR 46'S AIRSPACE AS WELL. THESE RADIOS HAVE FAILED REPEATEDLY FOR YEARS. THIS SITUATION HAS THE POTENTIAL TO CAUSE THE WORST KIND OF AVIATION DISASTER.
