Martín has been a radio aficionado for more than 60 years. He talks on the radio every night from 6 p.m. to 7 p.m. in the workshop of his Buenos Aires home. Most of his "amigos del aire" (radio friends) are from Argentina, but he also regularly chats with a buddy in New York and has talked with people from Japan, Finland and Peru, among other countries.
