Weather Fax, Weatherfax, Radiofax, Fax and Marine Electronics

Radiofax or Weather Fax is transmitted in single sideband and uses frequency modulation. The signal shifts up or down a given amount to designate white or black pixels. A deviation less than that for a white or black pixel is taken to be a shade of grey. With correct tuning (1.9kHz below the carrier frequency for USB, above for LSB), the signal shares some characteristics with SSTV, with black at 1500Hz and peak white at 2300Hz.

Usually, 120 lines per minute (LPM) are sent (though some stations use 60 LPM or other values). A value known as the index of cooperation (IOC) must also be known to decode a radio fax transmission - this governs the image resolution, and derives from early radio fax machines which used drum readers, and is the product of the total line length and the number of lines per unit length. Weather Fax now is available on LCD display products, and no longer requires "stinky" aluminum anodized paper to be produced and displayed.
