Losing HD channels random
Hi the other night we dialed by FOX HD I think West but Im not positive and then we came back a few minutes later and it was gone and the Shaw rcvr said no signal. Now tonite its fine but NBC West is gone. I have a spredsheet it says NBC HD West is the same xpdr as ABC West HD which is fine. Is there a way on Shaw to see what xpdr you're on? All I can find is the instalation stuff that says signal strength and satellite but not xpdr.
Can someone tell me for sure if NBC and ABC are on the same xpdr and if not whose on the xpdr with NBC so I can try those channels? Has any body else seen channels just come and go random?
