Hidden means that unless it is available to you, you won't see it in the guide. That is a good thing ... you don't need to see South Bend locals "unsubscribed" in your guide, or any of the other 210+ markets that cannot be subscribed to from Chicago. Only the people who subscribe to Chicago locals need to see those channels.
I'm in the Chicagoland area and use the EA. I look at message #15 & near the top it lists 4 Chicago channels & says “(HD Hidden)” and also “Available“. But what does hidden & Available mean?
Available typically means someone can subscribe to the channels. It may not be you ... but the channels are available to someone.
http://uplink.jameslong.name/ has several lists, including by satellite location.
And is there a list of which channels are on which satellite?
Good ... apparently the fall back feature is working.
Last Tuesday we had some rain & snow, and even though the weather cleared up in the evening I had problems receiving a lot of the channels. I received the local HD channels such as CBS & NBC but not most of the "cable" ones such as FX HD or History HD. When I tuned in History HD there was message saying I was being changed to the SD channel & this did come in OK.
I'd say your receiver was confused. Your locals are on 61.5 (along with many SD national channels). All the HD national channels are on 72. Not having 72 but having 61.5 would mean you would get locals plus many SD channels.
The local HD channels indicated they were on sat at 61.5.
USA HD and TNT HD where a couple that did come in & were on sat at 72.
Yet when I went to the DVR Menu & looked at information, 77 was Yellow and 72 & 61.5 were Red with an “X”.
If 72 & 61.5 were Red & indicated no signal, how was I able to get all my locals & a few of the “cable” channels?
It came and went ... I had to brush the wet sticky stuff off a couple of nights ago because it came at just the right angle to cover my dish.
I’m presuming the small amount of snow that I could see on the dish has melted because everything appears to be working now.
