I just recently set up an Sony SAT HD200 reciever. I'm using a CM 4221 anntenna mounted in the attic. I'm recieving good signal strength on WCPO, WKRC, WSTR, WCVN, and WCET. I live in the N. Ky area and the terrain is fairly level.


I have two issues that I'm looking for advice on how to fix.


1. I can't recieve anything for WXIX. (Does this even broadcast?)

2. On WLWT, I get a signal that goes from good to weak and changes rather rapidly.


Before I start messing around with the set-up I'm trying to decide what the issue might be and the best things to try and fix this.


Thanks

Pete,


Welcome to AVS!


Yes, WXIX-DT 29(remap to 19-1) is on the air presently(Fri. 2:10pm). They were having problems and were non-decodable(or off air) between Last Friday and Yesterday afternoon, but they now are "fixed". If you haven't done so since yesterday afternoon you might want to try a channel rescan. Also, WXIX-DT is only "generally" on the air between 12pm and Midnight. WCET-DT also operates only from 8am to 11pm BTW,, the rest are 24/7.


More info on WXIX-DT's recent problem, and other Cincy issues in the Cincy thread(we do need to make a new one BTW, since this is the "summer 2003 Cincy thread) :

Are you using a amp/preamp? If so, it's possible might be getting some "overload" problems which are affecting WLWT-DT and/or WXIX-DT, and you might want to try it without the amp.


Also, are you seeing a lot of Ghosting from analog stations WCET 48 or for that matter WXIX 19 or the other Cincinnati analog UHF stations? If so, it might be a good indication Multipath is an issue for you which is one thing that might explain the "jumpiness" of your readings from WLWT-DT.


Concerning WLWT-DT as well as your overall reception, best thing I could suggest at this point would probably be to get the antenna outside(You may even be able to pull in the Dayton Stations) other than that, it may be quite beneifical to move your antenna around a bit in the attic to try to find a "sweet spot" for reception of WLWT-DT(and all the other stations too).


Hard to say exactly what is causing your "fluctuating meter readings" for WLWT-DT however --- It may be some sort of interference related issue, Receiver selectivity/sensitivity issue, or multipath issue.


Seems a little strange though, Since WLWT/WCET are "up high" on the same tower. Also WCET-DT is right next door on 34, WCET-DT doesn't send much power(relatively speaking) Towards the South due to their transmitting antenna's radiation pattern - For instance, WCET-DT sends as little as 7KW ERP towards the SSE, whearas WLWT-DT sends out 512KW ERP presently in all directions ...


If anything, of the two I'd more expect that you'd have problems with WCET-DT ... Seems as if I do recall some others perhaps having a problem in certian areas of N KY with WLWT-DT, which does make me wonder if perhaps some sort of "interference related" issue is involved ... For example, just speculating, but perhaps intermod products from VHF stations such as co-located cpo9/ DT10 could be an issue involved - Seems like that would affect ~31-33 though. And that 'generally speaking" receiver desense/tuner overload issues would affect other stations/frequencies as well ...


Let us know how it goes and good luck,

Thanks for the help.


I checked it out today and I'm now picking up WXIX. If it's been out since last friday, that explains it. Bad timing on my part. Friday was when I set everything up.


Thanks for the point to the Cincy thread.


I don't have an amp/preamp. I've thought about a multipath issue, but didn't think that would be causing the WXIX problem. Since that part is worked out, I plan to check for the ghosting on the analog channels and see if I can get the fluctuating signal fixed by changing my antenna location.


Will post my results.

I think it was bad timing on their part for not sending us a decodable signal for almost a week


At least it's straightened out now, and everything looked good tonight during Fox Widescreen. Certianly Not HD, but I think it looks really good from them(they upconvert the Widescreen 480p to 1080i for broadcast) when they do it right ...


Anyhow, Enjoy the HD+Hope it isn't too difficult for you to get good results from WLWT.
