The Sangean ATS-505, a current vintage shortwave radio, contains a neatly attached listing of the SW Bands, and defines the 21-meter band as 13.560 to 13.870mHz, where I operate a Part 15 station at 13.560.
However, a member here on the site pointed this out to be an error and informed us we are actually on the 22-meter band. I’ve been in the process of re-recording all my station identification announcements.
But tonight while exploring a great newly discovered website
I find that they list the 22-meter band as being 13.570 to 13.870mHz, which puts me back at 21-meters, saving all the trouble of re-recording.
