Picture of DTV

Preparations for the DTV transition at the Tamaroa site begin with thorough equipment inspections.

removal of the original transmitter Every detail was noted in preparation for the removal of the original transmitter, which occupied a large space in the facility. The momentous occasion occurred in August 2001, making ample room for the new DTV and Analog transmitters required for WSIU to meet the digital conversion mandate. Because this transmitter was no longer in use, its removal did not affect our broadcast signal transmission. August 2001, Tamaroa, IL.

DTV conversion takes shape as staff make on-site acceptance (factory witness) trips to the Larcan factory in Mississauga, Ontario, Canada for the Tamaroa site equipment and to the Harris factory in Quincy, Illinois for the Dundas site equipment.

This analog transmitter will be installed at the Tamaroa site, enabling WSIU to continue to provide an analog signal for viewers until 85% of the area can receive the new DTV signal.
