There is a definite feeling that in an era where one's choices in music can be found on the web, a limited signal station with bare-bones programming is not going to have much impact.
The real issue here is signal. And with many people staying home, the listening in areas where car reception is good or passable while in-home listening is not will further reduce the AQH shares.
Remember, it's pretty much the laws of physics that say that any signal below 65 mV/m had a hard time achieving indoor reception. And that station has limited 65 dB/u coverage. In fact, it covers less than 20% of the market with its 65 dB/u signal, so stay at home means "I can't hear it at home so I can't listen".
Real Data: study of in-home and at-work listening in an assortment of diary markets using millions of quarter hours over a 4-year period. 80% of that listening is in the 70 dbu, and 95% in the 65 dB/u. Now, some of that has to do with most stations having their signal where most population lives, but it also has to do with the fact that under 65 dB/u just does not penetrate buildings well for reception on the average consumer raddio.
