LOGAN — Digital will replace analog television signals in Cache County on Aug. 30 — more than five months before the federal government makes it mandatory.

The switch means consumers must have cable or satellite service or a digital-ready set or converter box to continue watching television. Television stations across the country will be required by the federal government to broadcast entirely in digital by Feb. 17, 2009.

Cache County is making the switch earlier to prevent any interference when Franklin County, Idaho, makes the transition in September.

People whose televisions are not equipped to receive digital signals will need to buy converter boxes. Coupons for the boxes worth $40 are available from the federal government. It takes about three weeks to get the coupons by mail.
