Sky Digibox Default Transponder Frequency Settings
The Default Transponder setting on a Sky digibox tells the Sky digibox which frequency to download the channel list from when the Sky digibox is first powered on.
Changing the Sky Default Transponder Frequency does nothing what so ever for individual channel reception
The correct default transponder frequency setting on a Sky Digibox is 11778 V 27.5 2/3.
Prior to February 2015, this 11778 frequency used to be transmitted from a satellite beam which even the large 2.4m satellite dishes used to struggle to receive.
This meant that sometimes during the boot up process, the Sky Digibox would inform you that you were not receiving a signal. The box would not boot up correctly as it could not receive the required data and channel list from the 11778 frequency, as that frequency was simply too weak to receive.
