Ofcom recently opened a consultation about re-use & re-allocation of spectrum in the 143 – 169 MHz bands after the release of frequencies formerly used by the Emergency Services.
The formal document is available at http://stakeholders.ofcom.org.uk/binaries/consultations/vhf-143-169mhz/statement/VHF_Release_statement.pdf
As a result Ofcom has decided to temporarily offer the 1 MHz chunk between 146 & 147 MHz to radio amateurs on a non-protected non-interference basis subject to some geographic restrictions to try to prevent any interference to neighbouring countries. This will become available from 31st October 2014, via a NoV to individual licences.
If any interference is caused then the extra spectrum will be immediately withdrawn.
The NoV will only be available to Full licencees and the NoV will be time-limited to 12 months at a time. Ofcom reserves the right to reclaim this piece of the spectrum should it later be needed although they have said they intend to give 12 months notice should this be going to occur.
The NoV can be applied for through the RSGB website in the normal way.
