If it fits in the attic, sure. A real "fishbone" will probably work better than an apt-style model.
Perhaps some one can give me some info on this 811 OTA problem.
At certain times when I tune to a digital OTA station the signal meter indicates 80 - 88 % but I get the message - unable to lock. The other OTA stations will work fine. If I go to a Sat based station for a minute or two and then go back to that first OTA station the 811 will "see" the station and work correctly.
Note it is not just station station - it happen periodicaly to all my OTA digital stations.
I do not get analog OTA stations. Any body have an idea or just live with it.
Do you have the new software, version 266? What is your antenna configuration?
You may have to live with it. But, perhaps not for long. The 811's OTA reception is notoriously flaky. However, Dish is currently updating the 811's software. This update may have a fix. Previous updates have caused some improvement.
Power your 811 down for a while. The update should load automatically. I believe both the Sat and OTA led's will light while updating.
Thank you everyone
We will see what the new SW does.
You are absolutely correct, WJD about the "signal strength" indicator and multipath errors.
BTW, since some are reporting that their own multipath (or 49%) problems began or were aggravated by P265 I suspect that there was a trade-off between the bug fixes that it provided and marginal reception capability. If that is in fact the case I would not necessarily expect any improvement in future SW releases.
Now that P266 is in we will no doubt get some reports. But some of you guys may just have to start considering a different antenna or mounting position if possible.
Multipath is the bane of 8VSB DigitalTV reception. The more "directional" the antenna, the better.
Well, I bought the Channel Master 3016 and it just manages to fit between collar beams in my attic. I was fortunate to get the loan of a Leader LF941 TV Signal Level Meter from my Dish retailer, and used it to assist in pointing the antenna. Interestingly, WIVT-DT, the ABC local digital feed, is on low band VHF (channel 4) and I got the strongest reading on it of all the local digital channels. However, when I checked reception on my TV, the signal quality reading for this channel was (you guessed it!) 49! All the others are in the upper 80's. I'm going to have to try rotating the antenna a few degrees to the east to see if possible multipath problems can be cleared. Antennaweb.org states that WIVT-DT is at 134 degrees compass orientation from me, while all the others are at 137 degrees.
Remember that pointing an antenna is a 3D thing. You can elevate it too, that is point it above or below the horizon.
That's how Kirk defeated Kahn in the Motari Nebula.
Now that I think about it, aiming the antenna is a 2D thing, X and Y. 3D would involve moving to another location.
I have the 49% problem too- I imagine there are several of us lurkers that have this problem.......(OTA was fine- then bad w/ software "upgrade") :eek2:
Sounds like they are working the bugs out of the 811, but man I really wish it had a hard drive in it. I think I am going to wait for the 942, if they bring it out.
I just got my 811 Installed today , So far it working pretty good. My main problem is with the favorites . When I add my HD Locals to a HDTV favorite only two of the 12 stay!!! Also can not enter the Local station numbe 2- 69. It just stays onthe sation I'm currently on... Currently watch DSCHD. It is great pictures and sound. :hurah:
Try adding them as the digital channel number and not where they map to.
Joe - To tune in your local stations directly with the remote, you need to enter a 3 digit number. Example: for ch. 26, type 026. For ch. 2, type 002, etc. This will bring you to the Dish local channels, 002-0, 026-0, etc. If you want to go directly to the digital OTA channel, then type 0021 for 2.1, 0261, for 26.1, etc.
As for your favorites problems, I have no idea. I do know that at one time, if an OTA channel did not lock immediately, it would disappear from the EPG and favorites. It was fixed with one of the updates. However, it appears that the recent update P266 has brought this bug back.
I also reommend choosing "Display Dish Locals" from the "Disply Opts" setup screen in the Local Channel setup menu. It remap your Dish locals (82xx) to your local channels numbers, followed by a zero. That way, they sit next to your OTA channels in the EPG, to make up for Dish's glaring lack of OTA program info. It doesn't replace a proper OTA EPG, but it's the next best thing.
They fixed the problem .....
They? They? Do you mean the voices in your head?
811 Bug Issue?
I have been dealing with an intermittent double image problem on SD signals on OTA ATSC channels. For example, about every 30 seconds or so on UPN 21 (Dallas), I would see a double image. I have the 811 hooked up through a Gefen DVI switcher to Samsung 567 DLP. When UPN transmits in HD (1080i), I do not have a problem. This is true with several other locals. BTW, I ruled out the Gefen switch as the issue. This problem does not occur on the satellite channels.
I added an amplifier which improved my PBS reception. I had difficulty locking the channel before. The signal to noise ratio improved 5-10% across the board. I am 45 miles from the towers.
I asked Dish to send me a replacement 811 assuming there is something wrong with the receiver. Unfortunately the replacement 811 had the same issue. However I tried experimenting with the 811 HDTV settings (1080i vs 720p). My TV is 720p, but I have found that the TV does a much better job scaling 1080i to 720p then the 811 does. This is very noticeable on native 1080i channels such as HDNET while watching sports. So I usually leave the 811 set to 1080i.
The interesting thing is that I do not have a double image problem when the receiver is set to 720p on the OTA channels!!! So my work around is to set the receiver to 720p when watching local OTA channels in standard definition.
I contacted tech support, but I got the impression that he was not going to forward the info and just wanted me off of the phone. I detailed the issue when I sent the receiver back.
It would be interesting if others could reproduce the problem. If you have a native 720p TV with DVI, try your local channels with 720p and 1080i settings on the 811. You may need to leave the 1080i setting for 5 minutes or so for the double image to occur. For me, the frequency varied by channel.
I am having problems with my 811 dvi connection. All the blacks look like they are crushed and xrayed on dark contrast scenes. Dish claims no known bug on dvi outputs. I have read all the web boards and they clearly show that this is a known bug in the past. My question is is this still a problem with anyone else? I have a 57 inch Toshiba tv, just bought it from Bestbuy. Dish won't rma it unless I get Best Buy to chech the dvi connection with another dvi box , like a dvd player, to see that it is not my tv or cable. Short of getting into the tv settings hidden menus in the tv , is there anything I can do or is this Dish 's problem?
What do you mean by "X-ray"?
My TV was able to be adjusted for satisfactory DVI dark performance with the 811. S-Video is another matter.
