CALCULATION OF SAT IF FREQUENCY USING THE MSK 125 This is done as follows: IF = reception frequency - oscillation frequency The oscillation frequency is made up as follows: 9750 MHz oscillator frequency is used for a reception frequency between 10700 MHz and 11700 MHz. 10600 MHz is used for a reception frequency between 11700 MHz and 12750 MHz.
