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.
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
- Meteor scatter operation can take place up to 26kHz higher than the reference frequency
- 12.5kHz channels numbered RV48-RV63. RV48 input = 145.000 MHz, output=145.600 MHz
- 12.5kHz simplex channels numbered V16-V46. V16=145.200 MHz
- Emergency Communications Groups utilising this frequency should take steps to avoid interference to ISS operations in non-emergency situations
- Embedded data traffic is allowed with digital voice (DV)
- Simplex use only – no DV gateways
- EME activity using MGM is commonly practiced between 144.110-144.160 MHz
- 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
- In other countries IARU Region-1 recommend 145.375 MHz
- May be used for Emergency Communications and Community Events
- May be used for repeaters in other IARU Region-1 countries
- DV users are asked not to use this channel, and use 144.6125 MHz for calling
- 144.800 use should be NBFM to avoid interference to 144.8125 DV Gateways
Hеllo i am kavin, its my first occasion to сommenting anywhere, when i reaⅾ this paragraph i thought i coᥙld also make comment due to this good post.
I have been listening on 2M 144Mhz and all I get is white noise in Essex and most people on Facebook say they get the same
Yep, it is a bit quiet in Essex, I hardly ever hear anyone except on the nets on GB3DA.
Depending where you are, you may be able to join in with my local group (8 or 9 of us in North Essex/Suffolk border) on 144.700 FM late evenings. But even the group chat is sporadic and sometimes you may hear all of us on there, other times nobody come on for a few days. If you hear any of us at any time just jump in, we’re very easy going and chat about almost anything….
If everyone listens, then no-one is talking!
In many cases local knowledge is the key: Put out a call on known local repeaters, knowledge of clubs local chat frequencies is helpful too i.e. 144.725 is a local chat frequency not only for LEFARS in South Essex, but for Southend too. Then there is always the SSB calling channel (usually best worked with Horizontal Beam). Also look out for activity days like the upcoming 145 alive event taking place on Saturday 30th (between 12:00-14:00 UTC).
Yes, traffic on 2m is sporadic, but it is widespread. being in the right place at the right time is great.. I have put out calls at weird times of night on 144.500 and still got a rig check!
