At Leeds Bradford in 2004, the Watchman radar head was physically removed and sent away to Luton for refurbishment. During that time, ATC radar cover was the SSR, fed from the NATS site at Claxby. I expect it was NOTAM'ed but I don't suppose there were any significant delays. Perhaps there was a need for increased separation but I can't be sure.
