Rockford, IL - HDTV - Page 26

post #751 of 1188
Thank you all for answering my questions so quickly.

With my 27" SDTV the subchannels do get a little blurred at times but I have no problems with the main channels. Which brings me to another questions, can the FCC increase the amount of bandwidth allowed in the future or is it something that simply can't be done without interfering with other channels?

I contacted WIFR 23 last month after the 23 Weather Now went on the air and asked them about 23-3 and they said to expect 23-3 sometime next year and that the programming is still in question. They also said to expect to see an improved 23 Weather Now sometime in April.

Again, thankyou for your quick replys

I was wondering if anyone else was experiencing the same problem as me.

I live in Rochelle (about 20 miles south of Rockford) and I have a couple of antennas pointed in the northern direction. One is a Squareshooter (pointed at Rockford), and the other is a 91XG antenna (pointed at Madison, but also strengthening Rockford).

I have had no problems whatsoever with reception for Rockford on all channels until about two weeks ago. I now get a rather strange phenomenon. I have a reading of about 90% signal on my receiver, but WQRF HD has frequent tiny glitches. These are enough to drop the signal for a split second or so. I cannot tell if it is from the video feed coming from Rockford, or if it is something wrong with my setup (which never malfunctioned before).

To tell you the truth, I only noticed it because it altered my watching of the show "Twenty-Four" for the last two weeks. As of three weeks ago everything was perfect. I am wondering if anyone else has had any problems like this - before I go through my entire wiring and troubleshoot.

Thanks for any responses ahead of time.

Jason

You may be getting too much signal
post #754 of 1188
I must admit that I never thought that would occur with a 90% strength. Previously I would lose a channel on and off if the signal hit 60-65%. I didn't think that one had to keep a signal between 70 and 89% to get reception.

The only thing that makes me think that the signal isn't too strong is that other channels that are coming in with the same strength from Rockford don't have any problems.

I will admit though that I am no expert. I am keeping an open mind.

Hi UC,

You have to remember that WQRF is now Rockford's strongest station...by a factor of 6 fold. 22 miles east of you in DeKalb, with my ChannelMaster 4228 pointed towards Chicago in an attic antenna...they peg my signal meter with zero glitches.
With the massive gain you get from an XG-91, I am very convinced you are overloaded. If you can scrounge up a variable attenuator from a Radio Shack somewhere, tune it to channel 42 and see what happens. Betcha that does the trick. It really sounds like your tuner is being blasted with signal and it can't handle it.

Not sure if this is where to post this or not; however, I am in Rockford, IL and have a deep fringe antenna with Channel Master. I can receive Rockford, Madison, most-times Milwaukee and all of the Chicago stations expect CBS.

Does anyone have any suggestions?

Thanks.
post #757 of 1188
Welcome but suggestions for what? That sounds pretty good to me. I can only get Rockford and Madison.

Yeah, I have a suggestion - COUNT YOUR BLESSINGS and enjoy what you have!

If anyone can receive WBBM-DT regularly from 86 miles away in Rockford over the air, I can guarantee you they'll be in the Guinness Book of World Records as the first and only.

Why in the world would you need it anyway when you can get WIFR-DT steadily, and the other two markets most-times?

God - we should all be so lucky.

Hi SSW,

Welcome, and yes, this is the place to post! The last two people here are jealous of your great reception. As for me, I'll be blunt: how can I hook up to your system?

Seriously, you've done a great job! I assume your antenna is on a rotor, and has a preamplifier. Unfortunately, there is a problem with WBBM-DT: it broadcasts at low power on channel 3 from the Hancock Center in Chicago. As the others have alluded to, it doesn't get out far. The very best antennas can get it reliably out to 40 miles, and you need to have a very serious hunk of metal on the roof or in the attic with a massive preamplifier to make that happen. In short, outside of tropospheric ducting, or "skip", there's no way you'll ever get it reliably. They plan to move to channel 11 at very low power (1,180 watts) in 2009, and your high power FOX digital station up in Madison will effectively kill the signal from making it that far out.

Sorry we can't help on this one. If you think this is bad, us in the Chicago market have it worse trying to get a station we are supposed to get.
See the Chicago thread, for the link on "How to get WBBM-DT". It's an eye-opener.
post #760 of 1188
Yes, I have one of those gargantuan antennas on top of the house on a tripod with a rotor. Wife doesn't care for it too much, but comes in handy during football season. By the sound of things, I guess there is no room for me to complain.

Argh... I guess I can do it the old fashion way and turn off the boost that I give the signal when I split it within the house. Maybe that will be enough to crank down the WQRF signal. I will just have to remember to turn the boost back on when trying to pick up Madison. Thanks for the help.

If only Chicago wasn't blocked by so much crud in between. I guess that there is one good thing to say about Southern Wisconsin and its wide open farmland. 97 miles to Madison (great signal) and 82 miles to Chicago (can't pick up a thing).

Hello Rockford, Belvidere, Freeport and Dixon...welcome to Comcast!
It will happen, per the press release, by the end of this year.

So you are out in Rochelle. You can lock Madison, that's cool...can you get Quad Cities at all? Yes, the ridge at Creston blocks your signal.

To tell you the truth, I didn't really try to hit the Quad Cities. I was actually trying to pick up on WGN HD (Cubs Fan). I knew it was a remote possibility, but what the heck.

As for the signal strength with WQRF, I guess that I really was getting too much signal on that station. Thanks for the heads up on that one. You learn something new every day.

This leaves me with the new problem of having a perfect reception on 39.1 when I disconnect the XG-91 and use only the Squareshooter, but inconsistent reception on 23.1 unless I use the XG-91. What a strange way to send signals from Rockford. So much for broadcast standards when it comes to OTA signals. I suppose I cannot complain though. I am getting OTA HD essentially for free (minus commercials of course).

As a Cubs fan, I feel your pain.

Well, the problem is that when digital channels were picked, WQRF picked the most open one available. Sandwiched between multiple markets, everyone else picked channels that interfere with analog channels in Chicago, or South Bend...or in the case of WREX, why spend the money to go to 1 million watts when 160 kw covers the market nicely. WQRF wanted to blast out...they had the channel to do it...and they went nuts. But a hill up in Madison blocks many folks there from getting it. I don't know, for this market, if that much power has many advantages.
An engineer in Chicago told me that he thought 150 kw on UHF was fine for small markets. I thought he was wrong, but now that I have had 3 years experience with over-the-air DTV, he has a good point. If they want to get advertising revenue in the collar counties of Chicago (McHenry and northern Kane), that's one way of making it happen.

As for me, when all is said and done, I prefer the high power due to signal consistency. Unless, of course, you're using a very high gain antenna and a preamp just 20 miles from the transmitter.

What you could do is buy a "notch" filter, a single channel filter like a friend of mine had to do this week when the Champaign CBS station near his house went 1 million watts. They're around $60; you might get one cheaper on Ebay, or maybe another place I am not aware of currently...

Now when 17-1 goes from commercials back to the program (this seems to be the transition point that is causing the problem), my box doesn't reboot like it had before (Samsung SIR-TS360) but now looses audio (picture continues to come in fine), and stops responding to the remote control or front panel controls. It requires a hard reset to get going again, and also triggers the Samsung "click of death" on this box (at least did the three times I let it happen last night, tonight I tried it once to see if the problem still exists and the click-of-death didn't happen).

The click-of-death is where on reset or power-up the box has a relay in there that chatters for quite a while until it eventually settles down (some indeterminate length of time, power-on/off doesn't help it just has to work through it's issues it seems) and then starts its normal boot-up process.

Anyway, so 17-1 is again giving my poor Samsung box grief. I should have known, being a computer guy, that digital processing for OTA reception was going to be the beginning of a whole new set of nightmares in the video world.

Welcome to my nightmare!!! In all seriousness some tuners and their chipsets are more sensitive to glitches in a switch than others. I have a multiplexer/demux that unclocks the audio (briefly) when there's a switch because it they don't like the glitchy switch. You are correct is saying the "new nightmares in the video world." Digital isn't text-book yet.

Do you really want to know how far your favorite Rockford analog and digital stations go? Longley-Rice maps are the best way to tell, and are what is used by the FCC to determine coverage area.

You need to grab Andy S. Lee's Chicago map, to be used in Google Earth or any GIS program that accepts .kmz file extensions for display. This file now includes the Rockford stations. The download link is in the following post, scroll down below the WGN-DT coverage map:

http://www.avsforum.com/avs-vb/showt...&#post10127219

It is a 66 MB file, so be careful if you are using dial-up...best to leave the computer on overnight for that. :-)

If you absolutely cannot use Bit torrent to grab the file...grab a copy from my website.

Very interesting!!!!

I have a Sony A2000 and use the digital output to send the audio to my receiver. I have noticed that ABC (WTVO and WKOW as well) has quite a bit lower level of volume compared to CBS, NBC and FOX. Does anyone know the reason for this? Is there something I can change to help this?

I am using a silver sensor antenna.

In the digital world, standards really haven't been enforced yet. Its coming soon.

Here's hoping that the day will come when they develop and enforce resolution and bandwith standards, too (and keep them HIGH).

Agreed. Well, I'm glad to know that it is just an issue of them choosing to use different volume level and not something wrong with my setup.

Volume leveling is a big problem even with the commercials/shows we receive. Tone is set to 0db but the content is.......well . Our facility is calibrated on +4db = 0db. (NTSC standard) some of the shows we get are as high as +8, +10!!!! The sad part is there's nothing we can do about it because everything is file transfers.

Kinda hard to do. Its all file transfers. (Short of dubbing them to tape and re-dubbing back to server.)

Huh? if you check the levels incoming you dont get that problem regardless of your plant's levels. Use A to AES audio converters that have AGC on them. Fortel is a great manufacturer of these. You just feed a DARS signal from your sync generator into them and they take care of the rest.

We dont have level issues at all locally, or even need a level control or audio board like we used to.

The immediate answer is that the station is using the old Dolby Specs published from 1999. The last spec re-write (2005) increased the dial norm (actually decresed it but thats a different explaination) to bring it closer in line. If the station would revisit the ABC audio doc's, they would be much closer...HOWEVER...ABC as well as the other networks all have published specs for the station to use a a starting point. The station (or the systems integerator) should be monitoring the other stations and make the adjustment to bring them closer in line with the average in your area.

The biggest problem right now is that none of the networks can agree on a single setting. Each has their own idea of what the dialnorm level should be. Unless the local stations can get together and agree on a local level, it may never match. But at least it will be closer.

He has a suprise for you, but it has nothing to do with a subchannel. Our operators are busy enough with 3 stations let alone a 4th. Unless it will produce vast amounts of pure gold then we may add a subchannel.
