714 MHz (7 Channels) / BW 8 MHz / SR 6875
Esta ultima portadora (714 MHz) é a portadora principal da NOS em Portugal Continente. Esta portadora contem os descriptors dvb 0x82 e 0x83 que contem a grelha da NOS e apontam para as outras portadoras.
Por isso quando se faz a pesquisa de canais numa TV ou tuner/box basta fazer a pesquisa com opção de "NIT/Operador/rede/network/ou outra designação" e indicar apenas os parâmetros dessa portadora:
Frequency: 714.000 MHz (in mainland PT - see table below for other zones)
Modulation: 64 QAM
Symbol rate: 6875
Network ID: All (or 42838 for Coimbra headend - see table below for other headends - or just use All. Note, using All will make scanning channels a bit slower)
NIT (Network Information Table): Yes
LCN: ON
A NOS em breve vai ter que mudar essa portadora dos 714Mhz quando entrar o 2DD (2º Dividendo Digital) que obriga a libertação do espectro acima dos 700MHz
