After the Second World War there were so many radio stations operating on frequencies, which had not been registered that telecommunication regulators had to find a solution to this problem. First, a new international frequency list had to be drawn up; and secondly, a body had to be created to take care of future additions to the list.
The first world conference after the Second World War (at Mexico City in 1948-49) about frequency allocation focused on the high-frequency (HF) portion of the radio spectrum. This was especially important for international broadcasting and other forms of long-distance communications. The HF band (3-30 MHz) was also a restricted international resource and there had been an ongoing concern about its unfair use. With the number of parties interested in this resource growing it because increasingly difficult for administrations to get access to the overpopulated HF band. A crucial problems facing the Mexico conference in that required frequencies greatly exceeded available space in the radio spectrum. The creation of an allotment plan turned out to be very difficult, almost impossible.
The conference achieved only a facial solution (for only one region) and this has seriously emaciated by the refusal of the USA to sign the agreement. Among the reasons given were the fact that the USSR carried out jamming activities and that the plan allotted more frequency hours to the USSR than to the USA. The Second International High-Frequency Broadcasting Conference was equally unsuccessful in reaching an agreement. The conference took place at Florence/Rapallo, Italy in 1950 and, apart from the Soviet walk-out from the conference, there was still the problem of too many requests and too little space.
