| Notes to the Band Plan | |||||||||
| ITU-R Recommendation SM.328 (extract) | |||||||||
| Necessary bandwidth: For a given class of emission, the width of the frequency band which is just sufficient to | |||||||||
| ensure the transmission of information at the rate and with the quality required under specified conditions. | |||||||||
| The use of Amplitude Modulation (AM) is acceptable in the all modes segments but users are asked to consider | |||||||||
| adjacent channel activity when selecting operating frequencies. | |||||||||
| Foundation and Intermediate Licence holders are advised to check their licences for the permitted power limits and | |||||||||
| conditions applicable to their class of licence. | |||||||||
