8.33 khz radios.
All civil aircraft and Aeronautical Radio Stations operating on the VHF aeronautical band are having to change their radios from those with a bandwidth conducive to 25 khz spaced frequencies to 8.33 khz bandwidth. Invariably this means throwing out a working radio and replacing it.
Just out of curiosity, is this happening to aircraft/ground stations with UHF aeronautical band radios too?
