Use any web browser to search the WTR and find local frequencies to program into your scanner. Used mostly for commercial satellite television transmissions, C-band is becoming less of a residential option. A channel with nothing on its uplink is transmitted as a CW tone so it is possible to distinguish between an empty channel and a non-transmitting one. The bands of interest for satellite communications lie above 100 MHz.Higher frequencies are employed for satellite communication as the frequencies below 100 MHz are either reflected by the ionosphere or they suffer varying degrees of bending from their original paths due to . At the engineering level, there is what is known as sideband which is frequency spectrum that is set aside to create a separation between frequencies to prevent transmissions using adjacent frequencies from interfering with each other.

Most beacons are nominally horizontal polarisation, otherwise known as X polarisation. The other, NOAA 19, is quite healthy. This table shows all frequencies used for transmitting data to and from earth observation satellites or for microwave active or passive remote-sensing. Symbol Rate: 27500. The company was the first to petition the FCC to assign unused frequencies for satellite radio broadcast, which "provoked a furor among owners of both large and small [terrestrial] radio stations." 137-138 MHz The Satellite Band The frequency band between 136 and 138 MHz was, at one time, reserved for use in space research. Early days of Sirius [].
