    RSGB have around seven papers in development for the three IARU Region-1 Committees that will be meeting in 2019 - across C4-HF, C5-VHF+ and C7-EMC topics

    Attached in this thread are the two drafts destined for the C4-HF Committee covering:-
    • Harmonisation Considerations for Region-1/2/3 HF Band Plans
    • HF Mode Definitions (CW, Digital, Phone etc)

    Comments are welcome on this forum or can be fed to Ian Greenshields G4FSU, RSGB HF Manager

    NB: You will need to be logged in to see and comment...

    PS: The Document numbers will be updated once they become part of the overall IARU meetimng pack

    This is a bit pedantic, but we might as well get these things right. AIUI allocations to the amateur service in the band 1850 - 2000 kHz are done on a mixture of Article 4.4 and Footnote 5.96, not just Article 4.4.

    5.96 In Germany, Armenia, Austria, Azerbaijan, Belarus, Denmark, Estonia, Finland, Georgia, Hungary, Ireland, Israel, Jordan, Kazakstan, Latvia, Liechtenstein, Lithuania, Malta, Moldova, Norway, Uzbekistan, Poland, Kyrgyzstan, Slovakia, the Czech Rep., the United Kingdom, the Russian Federation, Sweden, Switzerland, Tajikistan, Turkmenistan and Ukraine, administrations may allocate up to 200 kHz to their amateur service in the bands 1715-1800 kHz and 1850-2000 kHz. However, when allocating the bands within this range to their amateur service, administrations shall, after prior consultation with administrations of neighbouring countries, take such steps as may be necessary to prevent harmful interference from their amateur service to the fixed and mobile services of other countries. The mean power of any amateur station shall not exceed 10 W. (WRC-2000)

    So rather than give more bandwidth to a mode that is not legally required, why not reduce the size of the cw portion of the bands and allocate them to digital modes? After all, cw is supposed to be very bandwidth efficient and able to get through in poor conditions or under congested frequency situations so surely does not need extended bandwidth but reduced bandwidth.

    Looking at the Region 1 & 2 Band plans is it the aim to get 7.2 to 7.3 for Region 1 Amateurs to harmonize us with Region 2 ?

    and Region 3?

    You have obviously never operated during a big contest or when a dxpedition is on. CW certainly needs every Hertz of its allocations in the bandplans.

    Thanks for the general comments

    CW is permitted throughout the band plan - but there is no doubt about the growth in Digital, which is why 80m and 30m have had adjustments in its favour recent years

    Also - this is a band plan thread - not a spectrum allocation one - so more 7.2-7.3 doesnt really feature. Until such time the other Primary Users give it back on a plate, there wont be any new expensive and risky IARU requests at a WRC either (AI-1.1 re 50 MHz is the last request for quite a while, as we focus on defending current stuff)

    I'm not sure what 'legally required' means in this context, or when we started using it this as a guide to band planning. CW is still a popular mode and also supports the construction of simple and effective radio equipment; a big part of our hobby. Digital modes can also be very bandwidth efficient and work well under difficult conditions, sometimes more so than CW.

    Anyway, the 60m view is a little too generic. The UK does not have harmonisation between 5351.5 and 5354. Its outside our band allocation. The big players in region 2, US and Canada, have a set of channels but they don't fall in this bracket either. There are only a few frequencies for UK stations to work US and Canadian stations: 5357, 5371.5 and 5403.5 for phone mode and only 5373 and 5405 for CW (lumped in with RTTY and data).

    Murray, will we see better harmonisation between UK and Region 2 for CW?

    The US and Canada both have processes in train for implementing the WRC-15 allocation so I expect that to improve the Region-2 situation in the not too distant future. Other countries over there are all aligned with the ITU allocation, but have the tighter ITU power limits as well.

    Meanwhile do not expect any change in the UK wrt to our own gaps unless we detect a different view from the Primary User
    (Australia is also reportedly struggling)

    Hi Murray

    Any idea when the RSGB C7 EMC topic will be available to view please ? To my mind it really should be at the top of the list as without proper EMC protection HF amateur bands are not going to useable soon.

    Best regards

    Apologies - our own C7-EMC paper (Noise Measurements) is below and was submitted later in the process.

    A few others are also now at: https://vienna.iaru-r1.org/conference-documents/c7/ - but thats not the full range of issues, so I expect more will be added and we may rethread the forum topics as we start to discuss other contributions as well
