Midian's INTERMOD-CALCULATOR predicts the possible occurrence of intermodulation products that may cause receiver interference at the radio repeater site. It does this by testing for odd and/or even order products caused by the mixing of multiple transmitters at a given site in a non-linear device. These may take the form of 2A-B, 3A-2B, etc., or A+B+C-D-E, etc. A non-modulated signal may not produce a direct hit. Therefore, a deviation window is provided to take into account modulated signals that are multiplied/mixed and sweep across the channel.

Other features of our Intermodulation Calculator include the support of frequencies from 1 MHz to 999 GHz, orders from 2nd to 33rd, a wide range of channel spacing (including 6.25 KHz) and generating of CSV reports that can be imported into Microsoft Excel. The software also allows for Latitude/Longitude coordinates for site location for internet based map lookups (i.e. Google Maps).
