Not just for digital communications but for all modes. We don't really need all of the frequencies that are being 'redistributed', but we sure need more than zero Mhz. This is almost promised in the future when we continue as secondary allocations. All of these advances in the radio art have been directly transferable to commercial technology and have generated many new markets. Many have said that amateur radio should fold up and go home, since many of the things that make amateur radio unique can be attained by cellular, PCS, and other such technologies.
Amateur radio is currently and has been in a paradigm shift for the last several years.
I am including the press release in the PSR in case you have not read it. This is the future. More like this to come. Amateur radio will no longer be able to continue to provide services that are better offered by this type of technology. We can no longer try to validate our presence on frequencies based on methods of operations developed in the first half of the century.
