occasional audio drops and pixelation. I personally think the PQ and Audio overall has been MOST EXCELLENT.

HiDef Dave,

I have consistently noticed the audio level on WPEC during HD broadcasts is very low compared to other channels such as WFOR and WPBF. Have you noticed this?

Guys,

We suddenly went off the air yesterday afternoon. Our Chief Engineer, George Danner and Engineer Keith Betts went out to the transmitter site and restored service.

I, too, have observed ocassional pixelation and dropouts since this episode, along with low audio.

By the way, just to confirm, we are only sending Dolby Surround via DD 2/0 for the Grammys show. WFOR-DT is sending DD 5.1, seemingly, except that the center (dialog) channel is on all three front channels along with what's supposed to be there.

We'll have a pow-wow about all this in the morning.

Could anyone tell me if the Grammies were broadcast in DD 5.1?

Thanks in advance,

Yes, they were, but only in some markets.

I live on Embassy Drive (off Palm Beach Lakes/Congress)
I can get WPBF most of the time without any problem, Channel 29 most of the time (so long as I dont bump the bowtie ), and Channel 34 some of the time.

What do I need to do to get WPEC and some of the others? I live in a townhousem. Do I need a huge antenna outside or something?

I have an old Panasonic HDTV receiver box (the one with the firewire). Would switching to one of those newer samsung units pull in a better signal?

Thanks,

Ed

The broad center channel was quite noticeable and annoying, but can anyone confirm WFOR was really sending 5.1?

My Yamaha amp almost always had the Dolby Digital light on for both channels 12 and 4. Some commercials seemed to switch the DolbyDigital word off and just show Digital.

WFOR was sending Dolby Digital 5.1. During the musical numbers I heard sound coming from all five speakers, and the channel indicators on my AV receiver confirmed this.

Thanks.

Looks like its time to check my cabling. I took the HD receiver out to help someone else get set up and must have messed up putting it back in the cabinet.

Just because your DD decoder indicates "AC-3", "Dolby Digital 5.1" or "3/2" when you're tuned to a DTV station doesn't mean you're actually getting DD 5.1 audio. I know, because my station and many, many others are sending audio streams that are masquerading as DD 5.1 when it's really not.

WFOR-DT was sending an AC-3 DD 5.1 flag last night during the Grammys but it wasn't correctly encoded...as a result we got dialog across all three front channels mixed with discrete front left and right and discrete rear left and right plus the LFE channel. (HDNet has done this, too.) My station, WPEC-DT, decodes the DD 2/0 Dolby surround feed from CBS HD and encodes it as DD 5.1. Neither of the two stations is supposed to be doing these things and they'll be eventually rectified. But be aware that you're not yet getting what you're supposed to be getting.

The "growing pains" continue.

David - any update on the current drop out and pixelization problems? Saturday night I tried watching "The Agency" and finally gave up due to the video-audio problems. It was during that storm front coming through, but my digital signal strength was still showing 86 - 93. Last night the Grammy's were better, but still many more pixelization problems than previously.

Len,

I'm informed that our encoder has developed a problem. We are in contact with our DTV equipment vendor in search of a remedy.

Once again WFLX-DT was off the air last night. I guess that I'm going to have to arrange my antennas to try for WSVN-DT.

Good luck is right. I can occasionally get them due to tropo conditions but even with the 4228 25ft in the air and a CM Spartan3 pre-amp I still only pull a 15-20 signal on them normally.

Thanks. I guess I won't even try then. Dave, I know that WFLX uses some of your news resources. Do you know why they have so many problems with their DT?

From 60-70 miles away, my usual WFLX-DT reception is in the 70s with a basic RS UHF/VHF antenna (no pre-amp) at 25 feet aimed at the Hallandale towers. (All of the Miami channels come in at 100 from about 25 miles.)

At the same time, my usual WPEC-DT reading is in the teens. David?

Actually, no, I don't know. We produce all of Fox 29's newscasts here at our studio and just send them to the WFLX studio live over a microwave link. So, we're just "one more source" of programming for them.

Bighitter,
The WSVN-DT signal is on VHF Ch. 8, and the 4228 is UHF only antenna, so it has no gain on VHF signal, as a matter of fact, it's very inefficient at that frequency. When I lived in Boca, I had one, and at the beginning I tried to use it for both, but didn't work for WSVN and WPLG, since both are on VHF, and you are farther north. I had to add a VHF-Hi antenna in order to get those stations. Just check your analog signal on WSVN and WPLG, and you'll probably get a weak signal. Check for some of my older postings (about a year ago) explaining what antenna set-up I used and where I obtained them.

Best viewing,

Jose

Good Point W2JD,

I should have thought about that before posting the reply. I guess I had the thought of the RS DBT in my head still from when I sold it to ElectricPickle and was thinking UHF only. Indeed someone with a decent VHF antenna should be able to pick it up. Thanks for correcting me on that as I would hate to lead others astray.

My Pre-AMP is a VHF/UHF pre-amp so it is not filtering out the VHF frequencies which is why I still get decent signals from them just not enough to lock in a picture most of the time. However last nite I was pulling 75%+ signals on both channels.

I have my antenna in the attic so there is no chance of getting WSVN. I may have to eventually put up a mast, but only if I have to. I guess I'm hoping that WFLX will get their stuff together.

WLRN 17.1 (20.1) is finally broadcasting the HD Demo Loop and it looks terrible. I am no expert but, I am willing to bet they are allocating to much bandwidth to the sub-channel and it is cause poor picture quality on the main channel.

Does anyone have an updated "go-live" date for WPTV-D, W. Palm Beach NBC HD? For such a brand new progressive, "state-of-the-art" facility, they sure seem behind the curve about broadcasting in HD ;-( Thanks.

I sent an email to Bill Peterson and WPTV a few weeks ago and this is his reply:
Feb 6, 2003

Quote:


We are just completing construction on a new tower, which was needed to
accommodate the additional antennas. Our antennas were lifted to the top of
the tower last week. The transmission lines have been installed. Now, we
have to test the transmission lines and connect them to the transmitters.
Our digital transmitter, on Channel 55, has been installed and tested, but
is having a minor problem that the manufacturer is remedying. That's
probably more than you want to know.


The bottom line is we anticipate having Channel 55 broadcasting in early
March.


Sincerely,


Bill Peterson
WPTV

Everything I see says Mar 21.

Sorry I don't have the model number as it has been a year since the install but I have an all in one antenna in the attic that also does FM and I am in the Coral Springs area. I am having a lot of trouble with channel 10 and channel 7. On 10 it is all static and I get the alternate audio message every time I change the channel and go back to it. Anyone else get this? I do not receive any channel 10 digital channel at all. I don't believe I get one on 7 but I can pick up all the other Fox's in the area. I am not using a booster as I tried one from RS and it made no difference.

I have a DTC-100 so I can put a second antenna on the "B" side if that will help. Please advise what I can do while keeping the antenna in the attic. I thought it was a UHF problem but from reading it seems it is actually a VHF problem is this correct? TIA

I get everything in Coral Springs with a little trouble from 25.1 WPBF in stuart. It's in and out. I use two RS UHF Yagi's at 65', one N and one S split with the pre amp on th N yagi to help WPBF.

Yes, WSVN-DT is on channel 8 and WPLG-DT is on channnel 9, both of which are VHF. Maybe you need to re-aim your antenna toward those stations?

Go to www.antennaweb.org for a radial map of station directions relative to your house.

They are looking at a mid-April launch. The delay is due to tower issues.

What kind of tower issues? The other posting from this week seemed to indicate their only problem was from the transmission equipment.
