133.75 has been almost unusable for several months now. Controllers have been shutting off the lrd site and using the qxb site only to reduce static and missed communications. Recently the areas in which we cannot communication with aircraft have increased. The controller working the radar position has been certified for 1 day on that position. Traffic was moderate. The controller was unable to communication with 2 aircraft and became distraction. Our workload increased to the point that neither of us were able to maintain scan as the radar controller tried to switch between transmitters and receivers to get readbacks from the aircraft. I informed the first supervisor of the problem and he told me to let him know if it happened again. This is a joke in the specialty because a supervisor yrs ago was told that a controller had lost all his frequencys. The supervisor told him 'if it happens again; let me know.' I informed a second supervisor about the problem; and he took no action. I informed a third supervisor when he came back from break and he reported the issue. The communication unit said that this was the first they had heard of the problem. I have reported it no less than 20 times and I'm just 1 of more than 30 controllers.

Title: ZHU CTLR VOICED CONCERN REGARDING ONGOING RADIO PROBLEMS WITH FREQ 133.75.
Narrative: 133.75 HAS BEEN ALMOST UNUSABLE FOR SEVERAL MONTHS NOW. CTLRS HAVE BEEN SHUTTING OFF THE LRD SITE AND USING THE QXB SITE ONLY TO REDUCE STATIC AND MISSED COMS. RECENTLY THE AREAS IN WHICH WE CANNOT COM WITH ACFT HAVE INCREASED. THE CTLR WORKING THE RADAR POS HAS BEEN CERTIFIED FOR 1 DAY ON THAT POS. TFC WAS MODERATE. THE CTLR WAS UNABLE TO COM WITH 2 ACFT AND BECAME DISTR. OUR WORKLOAD INCREASED TO THE POINT THAT NEITHER OF US WERE ABLE TO MAINTAIN SCAN AS THE RADAR CTLR TRIED TO SWITCH BTWN XMITTERS AND RECEIVERS TO GET READBACKS FROM THE ACFT. I INFORMED THE FIRST SUPVR OF THE PROB AND HE TOLD ME TO LET HIM KNOW IF IT HAPPENED AGAIN. THIS IS A JOKE IN THE SPECIALTY BECAUSE A SUPVR YRS AGO WAS TOLD THAT A CTLR HAD LOST ALL HIS FREQS. THE SUPVR TOLD HIM 'IF IT HAPPENS AGAIN; LET ME KNOW.' I INFORMED A SECOND SUPVR ABOUT THE PROB; AND HE TOOK NO ACTION. I INFORMED A THIRD SUPVR WHEN HE CAME BACK FROM BREAK AND HE RPTED THE ISSUE. THE COM UNIT SAID THAT THIS WAS THE FIRST THEY HAD HEARD OF THE PROB. I HAVE RPTED IT NO LESS THAN 20 TIMES AND I'M JUST 1 OF MORE THAN 30 CTLRS.
