Editor note; As a general statement the United States government no longer uses the letter designations shown in the table above. The US government considers the designations to be legally ambiguous [if memory serves]. It seems that in some cases the military still uses many of these designations, but many of those documents are not updated for years at a time. I have a note on another page where I indicate that: Letter designators of radio frequency bands are imprecise, deprecated, and legally obsolete. However I did not make note of which government agency said that, although it would seem that the FCC would be the agency putting out a statement like that.
