    They do!! The ARRL Spectrum Defense folks are on top of the relentless assault on all of our bands. They seem to do some good work.

    I think they could benefit from better communication about their efforts and results. I looked at the ARRL website, not much there.

    Of course, that's only in US, not much help for Brazil.

    Think beyond CW and SSB. Think about high bit rates. Think about spread spectrum. Think about advancing the state of the radio art!!

    Welcome to reality...

    The UHF spectrum is extremely valuable for commercial users, and we
    have been lucky that these assaults have been delayed for so long time.

    In Sweden we lost 2300-2400 MHz years ago, and other Nordic countries are likely to lose both 2300 and 3400 MHz in the near future.

    The 2400 to 2450 MHz range is still available, but with a power restriction of 100 mW. Amateur radio is considered similar to WiFi and other "short range devices" in the eyes of the regulator.
    Hence this restriction, which has been challenged in Administrative Court but currently to no avail.
    The lawyers at the Swedish regulator have a very negative view of amateur radio and consider us irrelevant.

    More serious is the possibility that both 23 cm and 70 cm may be the next to be lost.

    Our generous allocations in the UHF/SHF ranges are a remnant of the conditions prevalent at the 1947 Atlantic City conference, and the world has changed considerably since.

    A lot of the spectrum given to hams way back when was considered useless to commercial interests. This idea that we were recognized back then, but not now, is a fallacy. OK...maybe be a bit, but nothing to justify the spectrum we were given.

    Times have changed, technology has advanced, and the spectrum is worth a lot of money. Spectrum protection is going to be a struggle. Even HF is not safe. Who knows where this is all going to end?

    Another aspect is that a lot, probably a large majority of all radio amateurs, are convinced that if a frequency range should be allocated to amateur radio in the frequency allocations table (Article 5) in ITU-RR, it will always be provided for all the world's amateurs.

    This is not the case. Any Administration have the choice of permitting amateur access to all or a fraction, or even nothing, of a band that has amateur radio as either a primary or secondary user. They however cannot allocate more, without either filing a footnote, or by invoking Article 4.4.

    Allocating spectrum that is exclusive amateur in ranges that have regular international propagation to other users is more difficult, but is not unheard of.

    One recent example (WRC-15) is the footnote (5.122) that
    does not permit amateur radio in the 3750-4000 kHz range in some countries in Region 2:

    "5.122 Alternative allocation: in Bolivia, Chile, Ecuador, Paraguay and Peru, the frequency band 3 750-4 000 kHz is allocated to the fixed and mobile, except aeronautical mobile, services on a primary basis"

    Other examples are the "carved up" 80 meter bands in Japan, Korea and Australia.

    It is very difficult to make predictions about the future demands for HF spectrum. It appears that "civilian customers" such as broadcasters currently have little interest, but military users still have an almost unsatiable appetite for spectrum.

    If the general view that amateur radio is "irrelevant" continues to spread among spectrum regulators world-wide we will have hard times coming at upcoming regional and global spectrum allocation conferences.

    We managed, through a stroke of luck, to get the 15 kHz on 60 m.

    Without a coordinated effort among the friends that amateur radio still had in the national delegations to WRC-15, this would have ended in nothing, or at best a Region 2 allocation.

    Amateur radio has got powerful enemies in some countries, and as more and more "friendly" officials retire, and are replaced by accountants and lawyers, the long-term prospects have become quite bleak.

    I don't say this with any satisfaction, but the 60M, LF, and VLF allocations may be the 'model' for the future, as far as regulators 'protect' amateur radio allocations.

    In a perverse kind of way, new narrowband modes may speed up the process.

    Allocations of this size may become the norm, if the regulators start to regularly monitor amateur band average usage and provide spectrum accordingly.

    They may very well find that the actual band usage is just a small fraction of the claimed, as one Administration in Western Europe recently did in conjunction with the IARU claim at WRC-19 for 2 more MHz on 6 meters in Region 1.

    The VHF/UHF bands, even in quite densely populated areas, usually have an occupancy that is so low that it is sometimes difficult to measure.

    Indeed. Outside of major contests - and those are normally on weekends only - and the FT8 segments, regulators can make the case for a reduction in allocations, based on usage, very easily.

    We better embrace Hi-Fi AM.o_O:D

    We have lots of radios on those 2 bands running 24/7. Those freqs are used for our Mesh Emcomm network. We have camera, phones, chat apps,etc all on those radios.
    So, we are using it to not lose it.

    @PA0MHS Who knows what sort of wide band or spread spectrum style modulation someone might want to experiment with. That is why we need these wideband microwave allocations.
