New York City ? Television viewers who use antennas and were expecting a few more months to prepare for digital TV may not have much time left before their sets go dark: Many stations still plan to drop analog broadcasts in less than two weeks.

When Congress postponed the mandatory transition to digital TV until June, it also gave stations the option to stick to the originally scheduled date of Feb. 17.

That means the shutdown of analog signals, which broadcasters had hoped would happen at nearly the same time nationwide, could now unfold in a confusing patchwork of different schedules.

Lawmakers wanted to address concerns that many households that receive TV signals through an antenna are not prepared for the switch. They were also mindful that a government fund has run out of money to subsidize digital converter boxes for older TVs.

Dozens of stations around the country now say they are going to take advantage of the option to drop analog broadcasts this month.

Many others are on the fence. The total number is likely to be in the hundreds, a substantial chunk and maybe even a majority of the country’s 1,796 full-power TV stations.
