c) arrangements are made whereby locators using the same frequency cannot radiate simultaneously. Note.— The Standard in Volume I, 3.4.4.4, specifies the equipment arrangements to be made. * The type of communications referred to in S27/9 may be regulated by administrations. 2007/70/II. szám ANNEX 10 — VOLUME V 4-1 1/11/01 CHAPTER 4. UTILIZATION OF FREQUENCIES ABOVE 30 MHz 4.1 Utilization in the band 117.975 – 137 MHz Introduction The band 118 – 132 MHz was allocated in 1947 by the Atlantic City ITU Radio Conference, and again in 1959 by the Geneva Conference, but with extension downwards to 117.975 MHz, for the exclusive use by the aeronautical mobile (R) service. ITU Radio Conferences subsequent to 1947 also made provisions for the use of the band 132 – 136 MHz for the aeronautical mobile (R) service under conditions which vary for the different ITU Regions, countries or combination of countries. The utilization of this band has been included in the Allotment Table in this chapter. The ITU World Administrative Radio Conference (1979) made provisions for the use of the band 136 – 137 MHz by the aeronautical mobile (R) service, subject to conditions of Nos. S5.203, S5.203A and S5.203B of the Radio Regulations. The use of frequencies in the 136 – 137 MHz part of the band must take account of the conditions contained in these notes. In the utilization of these bands, States’ attention is drawn to the possibility of harmful radio interference from non-aeronautical sources of radio frequency energy and the need to take appropriate measures to minimize its effects. This chapter deals with Standards and Recommended Practices relating to this band and includes matters pertaining to the selection of particular frequencies for various aeronautical purposes. These Standards are introduced by the following preface, which sets out the principles upon which the utilization of VHF on a worldwide basis with due regard to economy has been planned. Preface The utilization of VHF on a worldwide basis with due regard to economy and practicability requires a plan that will take into account:
