Radio Spectrum BandsThe use of letters to designate bands has long ago been declared obsolete.Nevertheless, people seem to continue to use them and add more letters as users moveup the microwave spectrum.The original definitions had very specific non-overlapping definitions (not counting sub-band definitions). Modern usage seems to associate the bands withwaveguide ranges.
