Here is a view of one of the many Telefunken HF curtain arrays at the other end of the island. The vertical wire pairs are the balanced feeders. 30 degrees to either side using the motorized slew switch, which selects various feeder lengths thereby changing the relative phase of the currents in the dipoles. This particular slew switch is part of a fiber-optic network of industrial computers controlled and monitored from the main control room at the site. I wrote the custom C code for the industrial computers, and programmed the main computer, a rack-mounted PC in the transmitter control room, using National Instruments' LabView 5.1.
Many broadcast engineers are also ham radio operators.
Puebla is one of the prettiest, cleanest cities in the world, not over-populated like some of its neighbors. The hospitality of the Mexican broadcast professionals is without compare. There is a strong family emphasis in the culture, and many wives and children attend these professional conferences. My wife, Ruth has been to many.
