Note 1:  Local traffic using narrow band modes should operate between 1296.500-1296.800 MHz during contests and band openings.
Note 2:  Stations in countries that do not have access to 1298-1300 MHz may also use the FM simplex segment
                for digital communications.        
Note 3:  IARU Region 1 recommended maximum bandwidth is 20 kHz. See also Note-7
Note 4:  deleted  
Note 5:  Embedded data traffic is allowed with digital voice (DV)  
Note 6:  Simplex use only - no DV gateways
Note 7:  1240.000-1240.750 has been designated by IARU as an alternative centre for narrowband activity and beacons
               Operations in this range should be on a flexible basis to enable coordinated activation of this alternate usage
Note 8:  The band 1240-1300MHz is subject to major replanning. Contact the Microwave Manager for further information
Note 9:  Repeaters and Migration to DATV, inc option for new DATV simplex are subject to further development and coordination 
Note-10:  QPSK 4 Mega-symbols/second maximum recommended 
LICENCE NOTES:   Amateur Service: Secondary User: 
                                  Amateur Satellite Service: 1,260-1,270 MHz: Secondary User Earth to Space only: 
                                  In the sub-band 1,298-1,300 MHz unattended operation is not allowed within 50km of SS206127 (Bude), 
                                  SE202577 (Harrogate), or in Northern Ireland.
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.
