The bands are different as well as spacing --- Japan is something like 76MHz to 108 with 100kHz spacing..... Not sure about other countries..

I will, if you will do a Fourier analysis of a waveform consisting of alternate quarter-cycles of a sine wave, so as to show, if you can, that it doesn't have harmonics up to the infinity-eth, with amplitudes inversely proportional to the harmonic orders. -- OOO - Own Opinions Only.
