    Band Frequency Ranges are as follows:
    BC Band.............545-1760kHz
    SW Band............6.0-15.0MHz

    Chassis and schematic used in this model also used in models 1850A, 1851, 1862, 1868, 1868A, 1870, 1921, 1931 and 7147, with some models combining the power switch with the tone control and thus having 4 knobs instead of 5.
