All this virtual channel and RF channel stuff!! What would happen if a DTV receiver were within reception of 2 different digital stations using the same virtual channel?
Or what if a DTV receiver were within reception of 2 different stations, 1 analog using and another digital; with the digital claiming the same virtual channel number as the analog? I could picture this happening with someone who has really good reception by using a well designed outdoor antenna on a mountain top. ------ Original Message ------ Received: Tue, 24 Feb 2009 12:47:27 PM PST From: "ks4ec" <[email protected]> To: [email protected] Subject: [Repeater-Builder] Re: Somewhat OT - How to make HDTV *really* work > I am not sure what this thread has to do with repeaters, but here > goes. > I found a list of my local stations with their digital "channel" > numbers and the actual RF channel s they are transmitting on.
