I hope that is not a "sarcastic" thanks...
Information such as what you want is either provided by a company such as BIA / Kelsey or done for the internal use of stations.
BIA spends lots of money keeping its radio database current. They track technical facilities, ownership, revenue, power ratios, ratings, staff, contact addresses and emails formats, coverage patterns and much more. They have a team of dedicated staffers doing this. To justify the work, they charge for it.
Stations in most markets give revenue data each month to MK or some other accounting firm. This allows stations to see their entire market and how revenue is splitting. You give your own data, but get back the picture of the whole market. Generally, MK data is covered by confidentiality agreements as stations have no interest in having listeners or the public track their billings.
So, if you want the data you have to pay for it.
