Until today, I had no knowledge that the 11m band was allocated to the amateur service in the USA prior to this being allocated to CB. I guess the nearest amateur bands today are 12m and 10m.
This appeared on the Amateur Radio Weekly email, with the original article being on Bas's blog at https://pe4bas.blogspot.com/ .
I was aware of the 5m band, but wonder what other allocations were made in the past? Possibly there were other odd allocations made locally such as the 73 kHz band in the UK at one time. In the UK a very few NoV permits were allocated near 9 kHz. I had one of them.
Some other countries had an 11m amateur band.
