The project was a technical success but a financial failure because the Serbian railroad could only pay HMV by barter in grain, not pounds sterling, due a foreign exchange crisis. As a result, he had to return to Vienna. He was still prevented from working as an engineer, but he found work as a journalist and printer, first at Randfunk (which developed a low-cost method of tabulating a radio program guide at the printer) and eventually landing at a social-democratic publisher, Vorwärts. The experience in printing proved crucial later. However, after the 1934
