IHeart should leave the thing alone, as is, and continue to let the flow of nickels and quarters going to San Antonio via stagecoach.
The problem with that concept is nothing stays the same. The expense of running it continues to grow. The new contract they signed with the union is based on current revenues, which are diminishing. The expense of moving the studio, the expense of running the huge transmitter, and anything else connected to it all contribute to new expenses. This kind of thing can be maintained for a while. But at some point, change will have to come, regardless of who owns it. There are lots of examples of AM stations around Boston that were once ratings powerhouses at one time, that are now barely existing, thanks to the passage of time.
