    Nope. This band has never been available in Region 1. Not in my time, that is.

    Region II has the
    1.25 meter band. That wasn’t the point.
    I’m not going to explain.

    I know what your point was. But I still believe that having 100MHz bandwidth for amateur use is quite pointless as I stated in my original post. Most of the SHF bands are quite empty and currently available modulation methods don't need that amount. So it is logical that we loose parts of the SHF bands to commercial applications. Someone argued that we might invent new modulation methods for amateur use that might need that kind of bandwidth but I seriously doubt that.

    Wide band modes are easily generated by transmit capable SDR's. Here's a 30 MHz wide DVB-S2 signal capable of 110 Mbps throughput.


    Here's a block diagram of my Internet backbone test bed.
