Receive chain
The signal from the satellite's narrowband transponder is received on 10.489 GHz. This signal is mixed with the local oscillator (9.75 GHz) in the LNB, and the IF frequency is 739 MHz. The IF is forwarded to the SDR dongle where it is decoded and displayed. The Bias-T supplies power to the LNB while being transparent to RF.
