Narrative:
An large transport, dca-gve-tpa, departed dca 85 degree right climbing to 5000'. Small aircraft, W10-ott-cge, level at 5000'. The west departure frequency 118.95 failed again, and an immediate climb was needed to separate the 2 aircraft. 118.95 should be replaced. Ucr filed 8/90. Callback conversation with reporter revealed the following: reporter stated the aircraft came within 2 mi of each other. He was unable to immediately activate the backup transmitter because the equipment is located at adw. He filed an ucr on the primary equipment and the equipment was fixed within 2 days. Management in citing budget restraints as the reason for not relocating the standby equipment to dca.

Title: STANDARD SEPARATION WAS LOST BETWEEN 2 ACFT WHEN THE CTLR'S TRANSMITTER FAILED AND BACKUP EQUIPMENT WAS NOT IMMEDIATELY AVAILABLE.
Narrative: AN LGT, DCA-GVE-TPA, DEPARTED DCA 85 DEG R CLBING TO 5000'. SMA, W10-OTT-CGE, LEVEL AT 5000'. THE W DEP FREQ 118.95 FAILED AGAIN, AND AN IMMEDIATE CLB WAS NEEDED TO SEPARATE THE 2 ACFT. 118.95 SHOULD BE REPLACED. UCR FILED 8/90. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: RPTR STATED THE ACFT CAME WITHIN 2 MI OF EACH OTHER. HE WAS UNABLE TO IMMEDIATELY ACTIVATE THE BACKUP XMITTER BECAUSE THE EQUIP IS LOCATED AT ADW. HE FILED AN UCR ON THE PRIMARY EQUIP AND THE EQUIP WAS FIXED WITHIN 2 DAYS. MGMNT IN CITING BUDGET RESTRAINTS AS THE REASON FOR NOT RELOCATING THE STANDBY EQUIP TO DCA.
