Any word on how long before they add it in the 700's like the others?
Is Cox offering WCJB -DT (in HD) if you have the HD box??? I thought they were still stuck negotiating a deal for this channel?
QAM stands for Quadrature Amplitude Modulation. It is the digital TV transmission format used for all over the air digital TV signals in the US. You MUST have a TV or other piece of equipment that has a QAM receiver to get digital channels from an antenna (over the air - OTA). You do not "need" a QAM receiver to tune normal (non-digital) cable channels on a basic cable connection without a cable box. You do not need a QAM receiver to get analog or digital channels if you have a satellite or cable box. IF the cable company chooses to put non-encrypted digital (usually HD) channels on their cable, you can receive them WITHOUT a cable box if you connect the cable directly to your QAM receiver equipment. If you have the cable box, there is probably no reason to bypass the box.
There is a lot of forum traffic stating that the FCC REQUIRES cable companies to put non-encrypted digital versions of all "local channels" they carry in their "basic tier" if that station is currently broadcasting a digital signal over the air. This means that basic cable subscribers with HD sets and QAM receivers do not need a cable box to get these channels. This is part of the mandatory switchover from analog to digital television. The FCC rules do NOT, supposedly, require the cable companies to tell you about this feature. Please note, the supposed rule ONLY applies to major networks and channels you might get with an antenna, not HBO (etc.) or the superstations.
Why does this matter?
Well, I am "stuck" with dish for two years and they seem to be in a protracted legal battle to get rights to provide HD versions of the major networks. Even if they got the rights tomorrow, they have bandwidth issues that will slow HD "local channels" to us small market folks. I can only get ABC OTA in HD using an antenna in NE Ocala. I can get a digital fox channel sometines but they do not broadcast in HD. I am happy with the HD content on dish EXCEPT for the major networks. If COX in Ocala were doing the same as ttlvdo says they do in Gainesville I could get the local channels in HD for only $13 more per month. My Dish HD-DVR would (probably) even let me record them and show me them in the channel guide like it does now for ABC (WCJB 20.1) coming in from the antenna I added.
Another Ocala Cox customer (Telgar) tried a cable scan without finding any channels. I was ready to write off the whole story as an urban legend. Now I feel it is my duty as a techno-junkie to get to the bottom of the story for those other of us satalite customers struggling to get MORE POWER (errr.. more HD).
I suspect normal basic cable customer have a low pass filter blocking the HD channels up at 100+. The quest for the truth continues. The other forum folks spreading the legend have discussed all kinds of FUD from the cable company aimed to make you believe you MUST get the box and all the other $$$ crud I do not need to get these HD channels. No normal salesperson at Cox will know anything about this. A quest truely worthy of urban legend status awaits. A quest almost as legendary as getting a waiver for all the HD channels from dish.
