2) The radiated power should be kept to the minimum value necessary to give the desired field strength at the service range. 3) The daylight service range of radiobeacons referred to in 1) above shall be based on the following field strengths: 4) Regions 1 and 2 70 microvolts per metre for radiobeacons north of 30° N; — 120 microvolts per metre for radiobeacons between 30° N and 30° — S; 70 microvolts per metre for radiobeacons south of 30° S. — 5) Region 3 70 microvolts per metre for radiobeacons north of 40° N; — 120 microvolts per metre for radiobeacons between 40° N and — 50° S; 70 microvolts per metre for radiobeacons south of 50° S. — The above provisions have the status of Regulations through the linked reference at Article 28 (28.23 and 28.24), which specifies the above as special rules which must be complied with. ICAO Annex 10 Frequency planning material relevant for NDB assignments is also contained in: i) Annex 10, Volume I, 3.4 Specification for non-directional radio — beacon (NDB); ii) Annex 10, Volume I, Attachment C Information and material for — guidance in the application of SARPs for ILS, VOR, PAR, 75 MHz marker beacons (en-route), NDB and DME; and iii) Annex 10, Volume V, Attachment A Considerations affecting the — deployment of LF/MF frequencies and the avoidance of harmful interference.
