Dear Editor, Re: Air America [“Skies Partly Cloudy,” News, March 17]: Nice article, but to say that the signal was occasionally poor and there was sometimes dead air is a big understatement. It would be more correct to say that they have done a "heck of a job" at KOKE over the past year. This is probably too strong a criticism. I am sure they have done the best they could have, given budget constraints, but it is amazing that the station survived all of this neglect. The good thing is, about a month ago, they have finally fixed the transmitter problems, most of the time-sync problems, and the dead air. As a result the local ads are coming back. I am optimistic about the next year. I am very disturbed by some recent programing changes. I understand they need to make a buck, but I am afraid they are ejecting too many shows, especially on the weekends. I think they would be better off reducing the reruns and play more once-a-week shows for variety. I have been a loyal listener for the past year, but I must say that I will be listening to something else more on the weekends. The get-rich-quick schemes, car show, and bargain-hunter show are not my thing.
