Band Plans

UK 2m Band Plan (144MHz)

UK 2m Band plan (144 -146 MHz) or sometimes called VHF for amateur radio operators. Foundation and Intermediate Licence holders are advised to check their licences for the permitted power limits and conditions applicable to their class of licence.

2m band plan
All band plans are based on the IARU International band plans, however, there may be slight variations to allow for local regulations. This 2m band plan is for UK based radio amateurs.

Notes to 2m band plan

  1. Meteor scatter operation can take place up to 26kHz higher than the reference frequency
  2. 12.5kHz channels numbered RV48-RV63. RV48 input = 145.000 MHz, output=145.600 MHz
  3. 12.5kHz simplex channels numbered V16-V46. V16=145.200 MHz
  4. Emergency Communications Groups utilising this frequency should take steps to avoid interference to ISS operations in non-emergency situations
  5. Embedded data traffic is allowed with digital voice (DV)
  6. Simplex use only – no DV gateways
  7. EME activity using MGM is commonly practiced between 144.110-144.160 MHz
  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
  9. In other countries IARU Region-1 recommend 145.375 MHz
  10. May be used for Emergency Communications and Community Events
  11. May be used for repeaters in other IARU Region-1 countries
  12. DV users are asked not to use this channel, and use 144.6125 MHz for calling
  13. 144.800 use should be NBFM to avoid interference to 144.8125 DV Gateways
