| Note 1: Meteor scatter operation can take place up to 26kHz higher than the reference frequency. | ||||
| Note 2: 12.5kHz channels numbered RV48-RV63. RV48 input = 145.000 MHz, output=145.600 MHz. | ||||
| Note 3: 12.5kHz simplex channels numbered V16-V47. V16=145.200 MHz. | ||||
| Note 4: Emergency Communications Groups utilising this frequency should take steps to avoid interference to ISS operations | ||||
| in non-emergency situations. | ||||
| Note 5: Embedded data traffic is allowed with digital voice (DV) | ||||
| Note 6: Simplex use only - no DV gateways | ||||
| Note 7: EME activity using MGM is commonly practised between 144.110-144.160 MHz | ||||
| Note 8: Amplitude Modulation (AM) is acceptable within the All Modes segment. AM usage is typically found on 144.550MHz. | ||||
| Users should consider adjacent channel activity when selecting operating frequencies | ||||
| Note 9: In other countries IARU Region-1 recommend 145.375 MHz | ||||
| Note 10: May be used for Emergency Communications and Community Events | ||||
| Note 11: May be used for repeaters in other IARU Region-1 countries | ||||
| Note 12: DV users are asked not to use this channel, and use 144.6125 MHz for calling. | ||||
| Note 13: not used | ||||
| Note 14: 144.800 use should be NBFM to avoid interference to 144.8125 DV Gateways | ||||
| LICENCE NOTES: Amateur Service and Amateur Satellite Service - Primary User. | ||||
| Beacons may be established for DF competitions except within 50 km of TA 012869 (Scarborough) | ||||
| 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. | ||||
