Fourth Class Marine Radio Operator This is a reference book containing past questions from the national examination for radio operators. Price: 2500 yen I passed the exam successfully, so how about it for those considering taking it? I have a Special Maritime Radio Operator license. It's easier to understand since there's no English, but the question format is different from the Special Maritime Radio Operator exam. Even so, you can manage with memorization. There are no bent pages or writing. There is a 1cm fold on the upper left of the back cover. This item has been handled by someone else, so please understand that there may be some page warping or overlooked imperfections. Price negotiation is not possible.
