The hams hardly used 11 meters when they had it, what makes you think
they would use it now if they got it back? Besides, the cbers have made
such a mess of it, it would take years to clean the filth out.

11M was sparsely used because it was not harmonically related to the
other HF bands (i.e., required a separate VFO band and couldn't be
multiplied to other HF bands). With today's synthesized radios, 11M
would be no more difficult to implement than any other band.

When the hams had 11M, they could also legally full duplex 10M and 11M
simultaneously for a real 2X conversation like the telephone.

And yes, I was on the 11M ham band in those days.
