CBS Chicago to begin OTA May 31 - Page 2  

post #31 of 298
BarryO,

WBBM is carried on cable channel 3 (OTA 2) so causing lots of interference from OTA DTV channel 3 to the cable signal would really be hurting themselves. With 65%+ cable penetration they really could not afford to wipe out several hundred thousand viewers.

Isn't the burden on them "to accept any interference eperienced, and not cause harmful interference to licensed users" (WBBM in this case)?

Some of the problem is the interconnect of the TV to the VCR and has nothing to do with AT&T. We are broadcasting in accordance with all FCC rules. But if we wipe our selves out we do no one any good.

It is a pleasant surprise to get some actual, timely information from a station for a change. Thanks.

By the way, I live in Marina City and will let the group know if I see any interference.

Hi all,

Good and bad news....

THE BAD NEWS>>>>
We will not be testing the HD transmitter tomorrow.

THE GOOD NEWS>>>>
We are preparing to test again on June 19th which, at this time, will include leaving the transmitter up at reduced power over night!

This will do several things...

1) Provide a true gauge of interference problems by transmitting during prime time when most households are watching TV. If the signal is causing harm to cable viewers, we would expect the Call Centers to see an increased call volume.

2) Will allow WBBM to compare overnight rating data and see if there is an impact on our analog signal which is on cable channel 3 in the downtown area.

We'll keep you posted.

Chuck, I was wondering if due to the untimely passing of Tim Weigel are you going to postpone the Tuesday test?

I'm sure I speak for may other WBBM views that we're very sorry that Tim lost his battle with cancer and he will be sorely missed. It was nice to see someone that really looked like he enjoyed doing his job.
post #36 of 298
Tim was as vibrant on the screen as he was off the screen. We will all miss Tim.

With that said, as of today we are still planing to move ahead with our testing on Tuesday.

Regards,
Chuck

Chuck,
I was wondering if you could tell us when the test will be starting and wrapping up so that we could program our STB
and see if we receive anything. Also would you care to speculate on the probability of programming continuing should the testing phase be a success. Any input or information would be greatly appreciated with regards to full implementation of HD signals for WBBM.

Best of luck,
Rick

Chuck,

Is CBS using a transmitter on the Hancock Bldg, or are you transmitting at a new location, as was suggested as a possibility from Mr. Ross some time ago?

BTW, I too will be anxiously awaiting a DTV signal tomorrow from CBS http://www.avsforum.com/ubb/smile.gif

Rick,

We hope to start transmitting between 9AM and 10AM at half power and continue thru the evening. The transmitter will be turned off Wednesday morning and data reviewed.
Following the analysis of the results will determine our next step.

We will know more on Wednesday.

Sclaws,

We are using the transmitter located on the Hancock. AT&T feels they have made progress in eliminating ingress issues on their Chicago systems. The tests we are conducting are to validate their success and also to identify any area that may need additional work.

The alternate site is still an option, but one that we may not need.

Like you, we can't wait to permanently turn on our HD transmitter!

Bump . .

And we are anxiously awaiting the beginning of the test here in West Aurora (60506). I will report back later with times and picture quality. Being in the far West viewing area, this info may help others not lucky enough to stay home today to test themselves . . .

Hello!

For my first AVS post I'd like to contribute my specs from the WBBM-DT testing this morning.

I live in Naperville (60565) near 87th and Modaff roads, about 45 miles southwest of downtown.

Using an E* 6000 w/OTA module and Channel Master 1162 antenna mounted outdoors on 2-story roof peak on 5' mast.(The 1162 is a BIG antenna).Also, no additional gain added to what the antenna is pulling in.

10:15 am--I was receiving a signal strength of 83%! Solid picture with no breakups.

10:40 am--signal scaled back to 72-75%...maybe power was being throttled during testing? Still a solid picture, though.

Hope this information will be of help to WBBM and other forum members! I'm looking forward to watching WBBM all day!

10:50 a.m. Still weak signal (or no signal) out in Western Aurora. I have a DTC-100 w/ new outdoor aerial.

Anyone with a DTC-100 receiving signal? What frequency is it on. I have been scanning 3, 3-1, 3-2 and 2-1. No luck yet.

Chuck, can you tell us what percentage of full power you are at now?

Here in Downers Grove, 19 miles west of the transmitter, the signal strength has been locked on 09 from 11am to 12noon. I'll be keeping the channel tuned in throughout the day and will make postings when changes are observed.
post #48 of 298
For the RCA DTC 100 type (I have the F38310 HDTV),I have the guides turned off and had to do a quick search before I could receive the signal. I am at work and instructed my son over the phone so I have no other details. I am 10 miles NW from Big John and the picture is stable.
post #49 of 298
Another no joy from Mundelein, at 11:30, (ZIP 60060-9140, far north west corner of the village). I've got a Radio Shack in the attic (about 860 feet above sea level) and using a Dish 6000 with 8VSB module. The signal strength ranges from zero to the mid 40's (receiver doesn't have any error info), never was able to get a picture but the tuner saw enough of the PSIP signal though to figure out channel 3 was really WBBM on 2-01. Using RG-6 coax, run is about 40 feet, no amplifier being used. For comparison I get the other digital channels (except PAX and WSNS, don't watch them so I don't know)in the 78% to 86% range. OH well, guess it's the NYPD Blue rerun tonight.

I watched part of the "PRICE IS RIGHT" this morning here in Naperviille. Apparently the power was fairly lowand it seemed like they tried at least 3 different levels while I was watching.
At signal strength 28-33 there was no picture and only random bursts of sound.

At signal strength 34-48 the picture was intermittent, sound fairly steady with only a few dropouts.

At signal strength 44-48 picture and sound were both steady with no dropouts.

Hi all,

Testing continues!

As of 3:45 PM we intend to keep the HD transmitter on through 9AM tomorrow at 1/3 power. If the cable call centers experience an overload of trouble calls this evening, we will shut it down.

We will keep you posted.

Chuck
