Mechanical Stations in the U.S. & Canada

Mechanical TV broadcast in the AM radio band (550-1600 kHz) in 1928 and 29. With 24 and 30 line systems, only about 10 kHz of bandwidth was needed, so standard radio channels could be used. Some stations also broadcast in the shortwave band. Beginning in 1930, the 2-3 mHz band was used for television, with 100 kHz channel width. 60 line systems required about 40 kHz of bandwidth. TV broadcasts could be identified by their distinctive sound.

This is a list of stations that broadcast mechanical television. All of these stations have been verified as actually being on the air, through magazine, book or newspaper accounts, or eyewitness accounts.
