Hoosiers across the state remain without access to television at home today because of a variety of problems after the national switch to digital.

Hundreds who purchased digital converter boxes found that technical problems caused the bulk of the issues. Many were unaware that even though they had a converter, an antenna was also required.

And many who had an antenna found that though it was branded as “digital” and sold over the past few years, the antenna was designed only for UHF stations.

The converter boxes allow older, analog sets to view digital signals. The digital signals are more efficient, freeing up airwaves for cell phones and other services.

Another common problem has been missing stations.

Peggy Kunkle, 52, Heltonville, said that since installing her converter boxes she is receiving only two stations on one of her televisions and none on the other. “Right now I guess I’m stuck. I’m keeping my fingers crossed, still hoping they will work things out.”

Government contracted call centers, set up to provide assistance in the conversion process, said they received hundreds of complaints. Many of the calls from Indiana residents came from rural areas.

“People farther out really have lost a lot (of stations) and that has upset a lot of people,’’ said Melissa Crowe of Consult IT Inc., which operates three call centers in Indiana.

The Federal Communication Commission said that more than 20 percent of the 317,450 callers to its help line on Friday had problems receiving at least one station, making it the most frequent problem after converter-box setup and requests for converter-box coupons.

If a station is missing, viewers should first try to force the converter box or digital TV to “rescan” the airwaves for channels that moved to new frequencies.

For those who aren’t helped by that, the FCC put out a new advisory Monday recommending, “double rescanning.” That involves disconnecting the antenna from the box or TV, rescanning, turning off the box or TV, then turning it back on, connecting the antenna and scanning one more time.

The procedure can clear the box or TV’s memory of saved channel information that is now incorrect, the commission said. Multiple rescans are not uncommon to get additional stations.
