Narrative:

Once again GGG lost radar during inclement WX. I was working west radar when we lost primary and secondary radar. While the lo/east controller tried to notify a supervisor, I started pushing buttons. I noticed we had lost both radar channels. I eventually got both radar channels back and things seemed to return to normal. Callback conversation with reporter revealed the following information: reporter stated that the radar outage occurred during the switchover to the standby generator at the radar site when commercial power failed.

Narrative: ONCE AGAIN GGG LOST RADAR DURING INCLEMENT WX. I WAS WORKING W RADAR WHEN WE LOST PRIMARY AND SECONDARY RADAR. WHILE THE LO/E CTLR TRIED TO NOTIFY A SUPVR, I STARTED PUSHING BUTTONS. I NOTICED WE HAD LOST BOTH RADAR CHANNELS. I EVENTUALLY GOT BOTH RADAR CHANNELS BACK AND THINGS SEEMED TO RETURN TO NORMAL. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT THE RADAR OUTAGE OCCURRED DURING THE SWITCHOVER TO THE STANDBY GENERATOR AT THE RADAR SITE WHEN COMMERCIAL PWR FAILED.
