The default transponder frequency settings tells the Sky digibox which frequency to download the channel list from when the digibox is first powered on.
Normally this frequency is 11778 V 27.5 2/3.
Prior to February 2014, Sky users in Spain may not have been able to receive the 11778 frequency. After a power cut, the Sky box would display a "No Satellite Signals is being received" message, as it could not locate the 11778 frequency. The Sky digibox would not be able to download the channel list, and therefore not boot up, and cease to function.
So, to get the Sky digibox functioning, you had to change the default transponder from 11778 to another frequency, allowing the Sky digibox to download the channel list from that other frequency.
Post February 2014,the 11778 frequency is stronger than ever in Spain, and so there is now no need to change the Default Transponder frequency settings on a Sky digibox.
Note that changing the default transponder frequency setting on a Sky digibox does nothing for individual channel reception.
