This was the only informative and intelligent explanation of what freebanding is that I could find when I googled it several months ago.
"Freebanding" is the act of operating HF equipment illegally on an 11-meter frequency, usually in SSB, and primarily in or slightly above the Citizen's Band (26.965-27.405 MHz). "Freeband" also refers to the band itself, just above the CB and below the 10-meter amateur band (28 MHz)." (eham.net Nov 5, 2003)
As I do enjoy listening to radio activity out there anyplace that people talk has a interest to me, even if it is on a band that I can not transmit on.
