I don't think you'll find many complaints about WCPO-DT prior to last summer ... They are indeed, very good about switching to the ABC HD feed and have been for the last 3 1/2 years I've been watching them .... In fact, prior to their studio move last summer, I would have called them among the best stations in the area for providing "quality" HD service ...
EVERY station in the area has had it's problems(some problems have been "addressed" much more quickly than others for "various reasons"), and you'll find reports on those problems in posts either here, or in older Cincinnati/Cincinnati related threads in the AVS archives all the way back to 99~2000 ....

Are you sure about that? What about the Tonight show last night?
There are several threads in the programming area which seem to indicate that NBC has had some issues on the network level with the HD feed during certian shows recently, especially the East Coast feed which is what our local NBC affiliate(s) use. That may have been what you've been experienceing. Here's the most recent of one of those threads :http://www.avsforum.com/avs-vb/showt...hreadid=507686

Tonight, NBC has "ER" at 10:00 in HD, CBS has "CSI" and "Without a Trace", Fox has "OC" followed by "Point Pleasant". I'll be watching "CSI". Nothing in HD on ABC tonight.
Don't forget the HD movie on WB (WSTR-DT/WBDT-DT) -- It was OAR and 2.35:1 AR when I checked it ... Also, WCVN-DT/WCET-DT/WPTD-DT offers PBS HD/Widescreen programming every night .... Tonight show is HD from WLWT-DT/WDTN-DT every night as well ...

Is NBC supposed to be having these shows in HD or these shows aren't in HD? I can't think of any shows I personally watch on NBC so I wouldn't know.
NBC offers many programs in HD. In HD from NBC+WLWT-DT/WDTN-DT , I personally regularly watch "American Dreams", "ER" and occasionally Tonight show. I haven't had much problems getting HD for those from WLWT-DT over the past ~2.5 years or more .... Then there was Daytona 500 HD last year(most Nascar races NBC carried were sent as widescreen SD upconverts), 2002+2004 HD HD Olympics, 2002~2004 triple crown/etc/etc.
See AVSforum Programming sypnosis here: http://www.avsforum.com/avs-vb/showt...hreadid=164671
for more details concerning available HD programming ...

I'm pretty clueless concerning what may be causing your problem, given your previous "experiments" with rabbit ears/etc for WCPO, and our previous discussions. Just some "stabs in the dark" follow FWIW :
Unless for some reason your internal tuner has very poor performance on VHF as compared to UHF for some odd reason(or if there is something wrong with it), or severe impulse noise issues(which would effect lo-VHF ch 2-6 moreso than hi-vhf ch 7-13 or UHF) are an issue for you, If you're getting the other Cincinnati stations(especially WSTR which is running low power for their UHF channel 33), I'd think you should be getting WCPO-DT in like gangbusters.
And, the analog stations 5,9,12 should be coming in somewhere between "crystal clear" and a "good signal but with ghosting - (Not "snowy" or plagued with interference) as well. For that matter, you should be seeing 2+7 Dayton to some extent, even with the issues with signal bloackage you are having with Dayton, especially If you are seeing anything on analog 40(WRCX-LP 40 Dayton - low power station) as you reported in a previous post. Since I believe you had said previously that 5,9+12 are pretty "snowy" looking, unless that's changed with the new antenna, for some reason it just seems like you aren't getting enough signal on VHF, which really shouldn't be happening from your distance.
I might think you just need to try to find a "sweet spot" for the antenna(sometimes it's easy to find a "dead spot" for a certian station, a foot or 2 left or right or back or forth can make a BIG difference), but I'm not sure that's the problem since you don't seem to be getting good results from ANY VHF station in the area, no matter what you do.
Just a thought ...although I can't think of anything you might have in the line that would be "blocking" VHF frequencies(but who knows) ... Besides the diplexers, what else do you have between the antenna+TV besides Coax ? From what you've described previously concerning your VHF reception, given your location, It almost seems as if you have the antenna hooked up to a "UHF only" input on a VHF/UHF band seperator ...
I wouldn't think you should be having any "serious enough" terrain issues to cause any difficulties for the Cincinnati stations(terrain issues are more of a problem for UHF reception than is the case for VHF anyway) from your location, however you might want to check the elevation info you are using for the various tower locations. Knowing where you are located(for instance, between I-75 and Towne Mall elevation ranges between 705FT~737FT above sea level - ASL), you're not 200 feet "above" the hill in Finneytown WSTR's tower sits on, it's 913 FT ASL at the base of the tower, WXIX tower is the lowest "tower base" in Cincinnati at 684FT ASL ...
In any event, it isn't the height of the base of the tower that is important, it's the height of the transmitting antenna(ASL, or HAAT/etc), and the curvature of Earth+any terrain in between that might cause any issues that is important ... WCVN digital antenna is at 1199FT ASL in N KY(the farthest station from you), the rest in Cincinnati area digital stations transmitting antennas are locatied between about 1600FT and 1900 FT ASL ... WCPO-DT's transmitting antenna, according to FCC info is at 1579 FT Above Sea level .... You can find precise info for the other stations here(be sure to choose the "detailed info+CDBS links" selection for your query in order to get the fully "detailed" information :http://www.fcc.gov/mb/video/tvq.html
Attached is a elevation profile for the "direct" signal path from about 1/2 way "back" Along Village dr.(at left), to WCPO's Tower(at right). I've drawn in the approximate height of WCPO-DT's antenna and connected the two points with the red line ... The lower red line I drew in is an rough approximation of the effect the curvature of the earth would have on the "actual" "line of sight" path from ~27 miles ... While it looks like there may be a slight terrain issue for you, It certianly shouldn't be a problem especially given the lower VHF frequency/longer wavelentgh involved and that you aren't having any problems with the Cincy area UHF's ... The terrain situation from my location is defintely worse than this -- and I can get WCPO-DT just fine with rabbit ears Indoors placed near a 2nd story window from 32 miles, and the analogs 5,9,12 are pretty much crystal clear, much better PQ from even the analogs than what you'd see PQ wise on Cable or satellite, SD analog or digital ...
I would also stress that although this sort of elevation profile can serve as a good "tool", The TV signals(and especially on VHF) don't actually quite travel in such a "straight line" fashion" ... as the signals in the airwaves(well, they're photons actually if you want to get down to the "Real" nitty gritty of it) propagate out from the tower, they actually tend to "bend" a little and "hug" the earth. Optical "line of sight", and RF(radio frequency) "line of sight" are actually 2 different things, although the higher the frequency involved(such as High UHF channels) the "closer" they are to being the same. Due to a bit of "refraction" of signals by the air that Allways happens in lower layers of the atmosphere, radio signals via VHF/UHF "RF line of sight("space wave") propagation do travel a bit farther beyond curvature of earth(the WCPO-DT signals would "run into" curvature of earth at about 55 miles distant from their tower), or any "bumps"(terrain) than is the case with "optical" line of sight ...Also -- The lower the frequency, the longer the wavelength, and the bit "farther" the signal can "bend" around the curvature of earth or terrain issues ... That's not to say if you had a 600 foot hill near you that you are living on the wrong side of, that you would be able to reliably receive a station with a 400FT tower broadcasting from the other side of the hill .... If it was VHF however(probably not UHF), it's a good possibility that you would see something from it ...
