In our part of the world, summer weather is here. We usually keep the air conditioning off as long as possible, but, finally, it was necessary today. Upstairs, where I produce Shortwave Radiogram, the effort of the AC is, at… Leer más ›

As a retired bureaucrat, I prefer to play radio. But occasionally I get involved in the debate about US international broadcasting, as in my recent opinion piece in The Hill. It’s a sequel to another piece in The Hill back… Leer más ›
