I've been looking at some radios that operate in the UHF range and have been seeing multiple bands listed in the specifications. It's usually listed similar to this:
UHF1: 400-470MHz; UHF2:450-520MHz; UHF3: 350-400MHz; UHF5: 806-941MHz
I thought maybe the numbering scheme was just an internal thing used by Chinese companies, but I've run across it with manufacturers in other countries.
Do these actually mean anything? Are UHF1, UHF2, UHF3, etc., designated anywhere by the ITU or other body? Do the different bands correlate to something such as a specific spacing?
