| Radio Times 15-Jul-1955. Divis entered service on 21-Jul-1955 with band I BBC TV on channel 1, replacing the temporary, low power transmitter at Glencairn. The vision signal was provided from a GPO receiving site at nearby Black Mountain, which received the channel 3 transmissions from Kirk o'Shotts. There is a link at the foot of this page to a GPO report of this installation. The vision programme feed was replaced in November 1956, being via off-air reception of the channel 2 transmissions from Holme Moss at Snaefell, on the Isle of Man, feeding a UHF link (641 MHz), to Divis. FM radio was added on 18-Mar-1956. The original three tier, top mounted, band I, superturnstile Tx aerials were replaced on 17-Dec-1965 to permit the installation of the UHF cylinder.
