Controller stated there was a loss of secondary radar and alphanumerics. Radar reports after channel change. Reporter claims some aircraft do not acquire, and that after receiving a handoff, its data was lost along with all radar return.

Narrative:
While working radar approach control -- a controller called upstairs to the cabin attendant and reported a loss of secondary radar and alphanumerics -- and to stop departures until further advised. No supervisor was in the TRACON at the time so a controller went back to the radar panel and changed radar channels, released stagger switch, and came back up on high voltage. Shortly after this the radar appeared to be returned to normal. The outage was never logged on appropriate FAA forms. At approximately XX36 a departure off a satellite airport never acquired a data block. Earlier an aircraft was handed off from ZFW and then lost his data block and all radar return. At XX30 air carrier X never acquired a data block. This is just a small sample of the constant equipment problems at this facility, jeopardizing safety.

Title: CTLR STATED THERE WAS A LOSS OF SECONDARY RADAR AND ALPHANUMERICS. RADAR RPTS AFTER CHANNEL CHANGE. RPTR CLAIMS SOME ACFT DO NOT ACQUIRE, AND THAT AFTER RECEIVING A HDOF, ITS DATA WAS LOST ALONG WITH ALL RADAR RETURN.
Narrative: WHILE WORKING RADAR APCH CTL -- A CTLR CALLED UPSTAIRS TO THE CAB AND RPTED A LOSS OF SECONDARY RADAR AND ALPHANUMERICS -- AND TO STOP DEPS UNTIL FURTHER ADVISED. NO SUPVR WAS IN THE TRACON AT THE TIME SO A CTLR WENT BACK TO THE RADAR PANEL AND CHANGED RADAR CHANNELS, RELEASED STAGGER SWITCH, AND CAME BACK UP ON HIGH VOLTAGE. SHORTLY AFTER THIS THE RADAR APPEARED TO BE RETURNED TO NORMAL. THE OUTAGE WAS NEVER LOGGED ON APPROPRIATE FAA FORMS. AT APPROX XX36 A DEP OFF A SATELLITE ARPT NEVER ACQUIRED A DATA BLOCK. EARLIER AN ACFT WAS HANDED OFF FROM ZFW AND THEN LOST HIS DATA BLOCK AND ALL RADAR RETURN. AT XX30 ACR X NEVER ACQUIRED A DATA BLOCK. THIS IS JUST A SMALL SAMPLE OF THE CONSTANT EQUIP PROBS AT THIS FACILITY, JEOPARDIZING SAFETY.
