A while back I found these great chapter sections from Mr. Thomas White's writings on radio broadcast history. Was not sure if this was the correct place to post but I know many of the stations mentioned in this forum are of the 3-call letter variety, are very old, and have great histories (a lot of the Blow-torch stations are mostly very old from what I gather).
Many of you radio buff's that I imagine populate this thread are likely already familar with Mr. Whites documentations on US radio broadcast history.
This chapter looks at the 3-letter call stations in the US, how they they got their call signs and when. Also gives a great accounting through time on which 3-letter call stations survived, which ones where dropped, which ones moved to FM, etc.
The information in this chapter has been updated through January 1, 2013.
