It was not used for any broadcast services for a decade after the closure of 405 line television in 1985. However, in 1995 a low powerVHFFMfiller for the four national BBC radio networks was added (at 125 watts, vertical polarisation only), improving reception along the M4 corridor betweenNewburyandSwindon.
