Narrative:
On 3/fri/88, at XA00, the frequencys on the sinca sector 08 (123.95/269.3), dublin sector 07 (126.42/353.9), and augusta sector 20 (128.1/323.0) were released for maintenance to repair a squeal on 126.42. The back up frequencys were unreliable and often unusable for communication with aircraft. Several times the sinca sector (11000-23000') also had to work the aircraft within the dublin sector (24000-33000') because the back up frequencys for the dublin sector did not work. Approximately XF00 the frequencys on south departure sector 21 (133.1/348.7) became unusable. The communication system that the ATC system is using is unreliable because of its age. Newer equipment is urgently required.

Title: ZTL ARTCC EXPERIENCED SEVERAL VHF AND UHF RADIO FREQ OUTAGES DURING HEAVY TRAFFIC PERIODS. NECESSARY TO COMBINE RADAR SECTORS DUE TO UNRELIABLE FREQS AND BACKUP COM EQUIPMENT.
Narrative: ON 3/FRI/88, AT XA00, THE FREQS ON THE SINCA SECTOR 08 (123.95/269.3), DUBLIN SECTOR 07 (126.42/353.9), AND AUGUSTA SECTOR 20 (128.1/323.0) WERE RELEASED FOR MAINT TO REPAIR A SQUEAL ON 126.42. THE BACK UP FREQS WERE UNRELIABLE AND OFTEN UNUSABLE FOR COM WITH ACFT. SEVERAL TIMES THE SINCA SECTOR (11000-23000') ALSO HAD TO WORK THE ACFT WITHIN THE DUBLIN SECTOR (24000-33000') BECAUSE THE BACK UP FREQS FOR THE DUBLIN SECTOR DID NOT WORK. APPROX XF00 THE FREQS ON S DEP SECTOR 21 (133.1/348.7) BECAME UNUSABLE. THE COM SYS THAT THE ATC SYS IS USING IS UNRELIABLE BECAUSE OF ITS AGE. NEWER EQUIP IS URGENTLY REQUIRED.
