    There are small allocations at 40MHz in Slovenia and South Africa. It is worth pushing for a small IARU wide allocation here mainly for Es experiments. Mid way between 10m and 6m this would allow some of us to try real experiments. Please try! Roger G3XBM

    I agree and it's worth noting that the GB3RAL beacon cluster already has 40MHz and 60MHz transmissions - so there is a precedent in the UK.

    Remember that we dont even have an allocation at 50MHz yet....

    Please see the new C3 spectrum and the C5 thread 50 MHz band plan papers

    and as it says in the C3 doc - you need full support/consensus of 193 governments...

    Murray, I may be obtuse but I don't understand your comment.

    In the ITU Radio Regs, please remember there is no international amateur allocation for 50 MHz in Region-1 (ie Europe, Africa, Middle East). We are very focussed on trying to fix this under WRC-19 Agenda Item 1.1. Our usage (and by other european countries) is effectively a national non-interference one. Only Region-2/3 have formal 50 MHz amateur allocations.

    Getting that change for Region-1 you might think ought to straightforward given the spread of 50 MHz national level licenses - but it is most definitely not. It needs agreement from first CEPT (where Russia and France have serious objections) and indeed all 193 ITU Member States. The impact of that on an ordinary amateur is both lower activity and a direct restriction in your UK personal licence. When you are abroad or Maritime Mobile in Region-1 international waters - 50 MHz usage may be barred. If you look on the other thread in this C3 forum, there is a new draft paper on 'Spectrum Prioritisation and Development' which covers the challenge and explains that CEPT/193 issue further.

    The recent 5MHz WRC result (and this weeks announcement in GB2RS re no 5MHz future changes) is proof that this is not an easy process. It is not free either - attending the Ofcom/CEPT prep meetings costs RSGB (ie members subs) quite a bit over the four years of that WRC15 cycle, and more in the run up to WRC-19. Smaller amateur radio societies in other countries often cant afford to do that and thus fail to get their governments fully on side.

    Returning to 40MHz. Years ago when we and the Danes did our 40 MHz beacons, other IARU Member Socs were formally encouraged to do likewise - nothing happened (not even in South Africa). If other amateurs cant even manage that (let alone convince their governments to have a Tx allocation) - then you can assume its not going to happen very quickly...

    We do recognise that some knowledge of propagation at 40MHz is a technical nice to have - but we need to be realistic re an 'allocation'

    PS. Dont forget members subs also have to go into protecting what we have first, before acquiring more.
    PPS. 50 MHz and 70 MHz are in the same boat of course - as they are national and not ITU allocations (A great Question for Advance exams that!)
    PPPS. Any future item for WRC-23 will need all those 193 states to approve it at WRC-19 just to even have it added to the agenda
    PPPPS. IARU is funded by IARU Member Socs - basically Progress needs Pounds (or Euro or whatever) - ie healthy membership subs for Member Socs

    Thanks Murray. Sorry, but why not, say, 100kHz at 40MHz in the UK and see which countries follow? The extra 1MHz at 70MHz and 144MHz seem to used by a very few. 2Mhz for, say, 20 amateurs for a few hours, seems a poor option. At 40MHz quite a few of us could REALLY add to radio science by REAL self training. Much better than working an Italian on 20m SSB with a bought rig, a bought linear and bought beam. Please, think of radio amateurs REALLY adding to science! OFCOM need a kick.
