Add initial transponder for Net Digital Brazil
Adds the initial transponder used on Net Digital on Sao Paulo state (specifically at Sao Jose dos Campos). The other transponders are automatically obtained by scan, so, there's no need to add them all. Channels are spaced by 6MHz, using NTSC-like Standard/IRC cable frequencies.
