Good question. I don't know exactly how many radios we have around Mars right now- but yeah, the book does describe how the initial "abort" sequence (that leads to his stranding) damages all the radio equipment they have with them to talk to earth. All the suits, vehicles, etc are only designed to talk to other (ie- local/near) and not long haul to earth. Not sure how realistic that is, but that's what I got from the book.
