This station belongs to the Cadena Melodia with key station in Bogota on 730 AM. Nowadays it is very hard to get any local identifications, but I have been lucky a few times the last year. Yesterday I had a Facebook-conversation with Jorge Conejo who is responsible for their Cadena Melodia Ubaté account. Jorge is the programador musical and lucotor of La Voz Amiga. You can find his photo https://www.facebook.com/photo.php?fbid=183164035149748&set=t.100004075843621&type=1&theater.
Jorge is the guy to the right. Below a studio photo ( estas imagenes las acabo de tomar con mi telefono movil ).
