I have noticed that the 11 m. band does not cover the total 'b' band because 27.805 MHz is not included. Because this frequency is widely used in the Netherlands, e.g. for expeditions into Africa, it would be nice if the missing portion of the band would be included.
Hamsphere bands only covers 100 khz, so it is impossible to cover all the extended CB band.
11 meters band coverage in centered int the 27.555 frequency which is a standard calling frequency.
Anyway, HamSphere is only a simulation, so there is norelations between HamSphere frequencies and real frequencies...
