Cable television has greatly increased the competition facing local and network TV. Now it may be on the threshold of doing the same to local radio. Utah TCI cable customers in the near future will be able to receive "Superadio" as part of their basic cable TV package. All that will be required for current cable subscribers will be a $9.95, one-time cost for a special device to hook up to their stereo.

This setup could eventually alter local radio dramatically. Ever wish you could have radio without commercials? Well, you will be able to have that on cable with the Superadio system. It will offer specialized music with no interruptions - no commercials and no talk.Six different stations (all in stereo sound) will initially be available: country-western music, classical, jazz, easy listening, new wave and even a kids' music station.

With the addition of radio on cable to the local radio listening pie, it will obviously mean that there will be less pie to go around. Some smaller radio stations might even be forced out of business or change drastically in order to survive.

Since many radio listeners might prefer the commercial-free "Superadio" at home, the main times that people will listen to local airwave radio would be when they are driving in a car or working in the yard. This might make the morning and afternoon drive times more important than ever to radio stations.

The summer might also become a more critical listening period since portable radios might be used a lot more in the outdoor season than the cable radio system inside the home might be.

Dan McCartey, Utah general manager for TCI, said that Superadio is definitely coming in the near future, although he couldn't provide a target date. He also indicated that a shortage of the special hookup devices is the only thing holding up the new service. TCI wants to have an adequate supply for potential customers.

McCartey said that installment of the cable radio system will be fairly easy if a customer's stereo is near his TV set. However, if the TV is downstairs and the stereo system is upstairs, there will have to be a connection cable between the two.

He explained that the $9.95 device is a sort of splitter attachment that connects the back of the stereo to the cable line.

Ken Bell, KSFI radio promotions director, said the real impact of radio on cable will depend on what kind of sound quality it can deliver. As an example, he noted that AM stereo cannot deliver a quality sound in automobiles unless vehicles are equipped with AM stereo receivers.

Of course only time will tell the local impact of Superadio, but specialty airwave stations - all-talk, news, etc. - might also become more important in the future since Superadio will be 100 percent music intensive.
