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.
Hence the values for ARD - Das Erste are:
IF = reception frequency - oscillation frequency
IF = 11836 MHz - 10600 MHz
IF = 1236 MHz
