History and use of the allocations by the amateur and amateur-satellite services
The amateur and amateur-satellite allocations of 248 – 250 GHz (primary) and 241 – 248 GHz (secondary) were made at the 1979 World Administrative Radio Conference. The allocations have been used for terrestrial propagation experiments; communication over paths as long as 114 km has been achieved. No amateur satellites have utilized the allocation yet.
