Chicago, IL - OTA - Page 394

post #11791 of 12035
So far, 20.2 is carrying FNX (PSIP name is "FNX") with correct guide info, 23.2 still is carrying Bounce with correct guide info, and 9.3 is airing ThisTV with correct guide info.  But 26.5 still has "THIS" as its PSIP name though it is showing Bounce programming; its guide info was still ThisTV's as of a couple of hours ago but now it's Bounce's guide info but an hour late as if the PSIP generator were already using CST.

On Comcast, we are screwed on ThisTV until December 4, when WGN 9.3 is added as channel 354. Now I have two copies of Bounce on the original and former ThisTV channels. We also don't get FNX until December 12. (Comcast seems to like to do channel changes Tue-Thu.)

windows media center tv OTA question

while adding the new channels to the WMC , something baffled me -
the WMC sees 48.1, U Too just fine and with 5 bars of signal
but the WMC does not see 48.2 TOUCH-TV at all and no bars of signal

any other WMC user for OTA encounter this?

any ideas why?

yeah i know i am not missing anything but it piqued my curiosity

As of Friday afternoon, 26.5 had Bounce's guide info with no time error any more, identical to 23.2's.
post #11796 of 12035
26.5's PSIP name changed to Bounce some time over the weekend.

RF39's programming is completely redundant for anyone who can receive RF27.  I wonder if Weigel has something else planned for 23.2 or 23.3 now.

Also, has anyone mentioned that WPVN has added Peace TV (PSIP name PEACETV) at 24.3?  Seems to be all Islamic-related programming.
post #11797 of 12035
I noticed it a few days ago when re-arranging a few things and hooking the RF input of my main TV to the antenna now that Comcast has gone 99.9% encryption (just the EAS details and OnDemand Preview are left.) I did update the Wikipedia page for WPVN.

I wonder why somebody edited the Chicago TV template there to put PeaceTV on 20.9?!? I guess I need to fix that.

i cant comment on your WMC problem but from what i've seen so far, 48.2 TOUCH TV may be a decent channel....its hard to explain but its kind of a strange mix of news, feature stories, commentaries, strange visuals, etc etc....

thanks for the update....i've also been wondering what happened to GET TV but i couldnt find anything about it....thats a long delay....i hope it happens...

The only thing I can suggest is to go into Edit Channels/Edit Sources for 48.2 and see if there are some sources listed that shouldnt be there. It should be behaving exactly like 48.1 does.

Receiving a station labeled WOCH-1 on 41.1 now over RF channel 49; as I can rarely pull in WOCK, I've no idea whether its programming matches that of the WOCK subchannel that carries WOCH.
post #11802 of 12035
Tuff tv 24.1 etc is now in 20.3 Thur 20.9 but still have pbs 20.3
post #11803 of 12035
That may be a PSIP problem, Ryadoggy, because WPVN's physical RF channel number is 20.  Right now I am receiving all WPVN channels as their normal virtual channels 24.1 through 24.7, but on other low-power stations I've often seen PSIP channel translation fail and what weak signal I could receive come in as the actual physical RF channel and stream number.

Meanwhile, how long has WCHU been airing Azteca America in 720p on 61.1?  I can't often pull WCHU in and just noticed that a few days ago.

Able to pick up 41.1 (clear picture) and 10.1-4? (snowy picture in darien il western suburbs
post #11805 of 12035
10.1-5 might be WWTO without enough PSIP info to read the virtual channel numbers (35.1 through 35.5); WWTO's physical channel is RF10.
post #11806 of 12035
But why would it be snowy? Unless there's some issue with some analog equipment at that station, a digital image shouldn't be snowy. Blocky and stuttering, yes, but not snowy.
post #11807 of 12035
Good point; something is funny if *any* ATSC channel has a snowy picture.

Dattier,

post #11809 of 12035
I've never studied engineering, just watched television, and therefore cannot guess how an NTSC picture, snowy or clear, would show up on a channel with a minor channel component.  Just saying it baffles me.

From the FCC Paperwork tonight. It appears that WOCK-CD wants to move from RF 4 to RF 41, that was WOCH-CA's former analog allotment.

The proposed contour shows a great null of almost the entire northwest suburban region.
post #11811 of 12035
I wonder if they'll be required to put a null in their signal to the south to protect WICD in Champaign, already on RF 41.
post #11812 of 12035
Providing there are no interference issues, should they be able to go to RF 41, it might be possible I could get this station better. I get them ok on RF 4, since I have an antenna optimized for RF 4. In the summer time at only 300 watts, it can't stay in with a steady signal. If they get their wish to vacate RF 4, that will make my Antennacraft CS600 antenna sort of obsolete, as it may leave just WBBM-TV on VHF (I bought the Antennacraft CS600 specifically for WOCK-CD). I might move the UHF antenna to the top of the pole, in order to get the other LPTV stations in better. I can get WBBM-TV with no problems, with my VHF antenna at a lower height (I also had no problems with WLS-TV when they were on RF 7 & my VHF antenna at a lower height).

Now looking at why WOCK-CD would have to null their signal to the NW, it's because of WIFR Rockford.

The filed paperwork already addresses it, and the answer is no.

... and a good chunk of the city; I'm barely inside the boundary and not confident about receiving such a signal.  Does the contour really need to be that severe to protect a signal that never reaches this far?

On another note, it means yet another clash of virtual vs. physical channel numbers, which bother many tuners.  We already have six of them in this DMA.  Two of our ATSC TVs don't handle that well; two do, but I had to figure out how to make them, since it's not covered in their manuals.

Yes.



The attached image shows the WIFR coverage area. Causing interference to any one of the red cells would be enough to make it ungrantable. Similarly, causing interference to any two of the orange ones would also make it ungrantable.

post #11816 of 12035
How much empty distance does there have to be between contours of stations on the same RF frequency, then, Trip?  The circle on the map you attached doesn't come within twenty miles (I'd estimate) of the null to the northwest on the proposed contour for WOCK on RF41.
post #11817 of 12035
The contour only bounds the coverage area. Contours are allowed to overlap as much or as little as anyone wants, as long as interference remains below 0.5% of the population.

The Longley-Rice interference is computed for any station within 300 km of each cell. So as long as, in this case, WOCK-CD 41 is within 300 km of the cells on the right, the interference will be computed for those cells. This is a simplification of the process, but if WIFR has, say, 50 dBu of signal at a given point, and WOCK-CD has 34 dBu, then it passes because the 15 dB ratio is met. But if WOCK-CD has 36 dBu, then it fails because 14 dB is less than the 15 dB minimum signal-noise level. If WOCK-CD was to put a fair amount of signal toward WIFR, regardless of where the respective contours are, it would most likely cause interference to at least some of those cells.

You never know what you'll see on the broadcast TV. I've seen DVD screensavers playing where the station obviously used a DVD player to broadcast a movie and just the other day, I noticed the Roku home screen on one of Chicago station's subchannels. Using a Roku and an internet stream as source material? eek.gif

OK, then treat my previous post as if I'd said "coverage area" instead of "contour."  I just don't see why the nulls have to be so (geographically) deep.  Surely a signal from downtown Chicago can go beyond Dakin Street before interfering with a station in Milwaukee and past Sauganash without clashing with one in Rockford.

The Roku thing is one of the WRJK (WJRK?) shopping channels if I remember. I posted about it a few weeks ago. I guess it's been that way for a very long time, or it keeps failing, but nobody is monitoring it.
