2008_05_07 A photo study of AM radio engineering

Radio and hacking have always overlapped. In my own case I came much closer to being a broadcast engineer than to being a computing one. Doing AM and FM transmitter site studies was even a bit of a business for me, back in the 1970s. It's interesting to see what this old analog art and science might still teach us. At hand is a visit to the transmitter site of WZZN, a 50,000-watt Boston sports station on 1510KHz that was once WMEX, a top 40 legend in Boston. This photo essay visits how AM stations protect each other's territories at night, when signals bounce off the sky.
