yes, cool tv is on comcast cable clear-QAM, londonderry NH headend.

in frightening/tragic news, a worker fell from one of the transmitter towers today, not sure which one. 1000 feet.

It was the tower on Chestnut St, mainly used for FM, but has two TV stations on it.

Anyone know what was going on last night (Dec 15th, early am) at 2/4/5/38 ? All of their transmitters went dark for about 3-4 hours, from around 12:45am until around 4:30am.

Was quite abrupt, obviously the tower did not fall over, and an electrical failure would have generator backup. Just curious as to what it was. Thought repair work, but during network programming?

Planned, once-a-year maintenance to sweep (electronically) the combiners and antennas to make sure they are still in good working order. That can only be done without power from the transmitters.

Thanks for the prompt reply and satisfying my curiosity! Since the stations now have 4:30 am newscasts, I can see why the maintenance started "early".

Over the last few months we have been having problems receiving channels 4 and 7. 5 seems OK. We live in newbury and have a high-gain UHF antenna, a VHF antenna (for 7) and a channelmaster preamp in the attic.

In general we have good reception until around 1 November except in extremely windy and rainy conditions. We would expect better performance now that the leaves have fallen, but instead it has gone the other way.

I am thinking that it is either a cable or an amplifier problem, but want to check to see if there were any other issues causing problems.

Any ideas?

There is no need for a VHF antenna for Boston stations, they're all UHF....
post #10240 of 10626
I thought that 7 was going to transition back to their VHF channel for their digital once the analog was discontinued. Did that never happen?
post #10241 of 10626
It went back to 7 for about 4 days before UHF 42 was lit up again. They made the move permanent shortly thereafter, and 7 is history.

You can aim your VHF antenna toward New Hampshire and try for WMUR-9 and WENH-11.

They did, reception was reported by many viewers to be much worse or non-existant on VHF, and they abandoned that plan and went back to UHF. It all happened within a very short time frame, if I recall.

Other stations around the country went through the same thing. Apparently the projections by their consultants and engineers about having adequate coverage on VHF didn't jive with reality.

The switch to UHF happened pretty quick. They simulcasted for a little while then shutdown RF 7.

I had no problem receiving WHDH on either RF 7 or 42 here in southern NH. Moving to UHF was great for us as all the MA stations are now on UHF and NH WMUR and WENH are on VHF. Offset the VHF antenna and now no longer need to use a rotor.

WGBH 44.1 HD continues to zoom non-16:9 ratio programs to fill the 16:9 TV frame resulting in cropped heads and half text loss on the bottom.

I have emailed them in the past (see my earlier posts), and have received a response that they retain the original artistic camera framing of the original program as a rule.

Someone is making the decision that the viewers want their widescreen HDTV filled ALL THE TIME. If the original program has not letterboxed their 4:3 ratio with custom side bars it will be butchered to fill the screen. Selecting a 1:1 pixel mapping confirms that this is the transmitted zoomed signal.

PBS OTA 44.1 has no clue. Possibly their merger with Comcast to add PBS HD to Comcast's programs required this absurd decision.
post #10245 of 10626
i just took a peek at 44.1 OTA and saw an ancient julia child "uprezzed" to HD and looking as OAR and as fuzzy as ever....
post #10246 of 10626
It appears the programs are hit or miss. Inside Washington was zoomed to fill the screen. Keeping Up Appearences has been zoomed. If Julia Child was given sidebars as a 16:9 1080i ratio there will be no zooming.

It seems when a program has an original 4:3 ratio without side bars included into a 16:9 frame it will be zoomed by default.
post #10247 of 10626
ah - yes, dent, that sounds annoying alright.
fwiw, if you have cable internet without video service, you would find lots of local TV channels on the cable, possibly including an SD version of 44.1 as wgbx or wgby. that version may have proper OAR and/or may be zoomable as you wish via your TV or tuner... (Many can zoom SD any which-way, but are stuck in "full" mode with an HD signal.)

Both WGBH and WENH maintain separate HD and SD feeds so they get to control and preserve the video image. I find it curious WGBH would take this tack on the WGBX HD feed.

I recently watched a couple of movies on 7.2 (This TV) and noticed that when I watch the signal with 1:1 pixel mapping, I can see the dotted lines at the top few pixels of the screen. I think this is digital data for closed captioning. Is this something that the network needs to fix? Is anyone else seeing this?
post #10250 of 10626
I have noticed recently, especially on Channel 4, WBZ-TV that most of the Avidia Bank commercials appear to have a much higher sound output level than other commercials. I have a Sony Dolby 5.1 sound system on my TV and after doing some interesting checks, came up with this observation:

Using my portable sound pressure level meter at a distance of 6 inches from each speaker, I put my sound volume at 25% on the stereo amplifier. I measured the output level in front of each of the 5 speakers at between 97 & 104 dB SPL.

I waited about another 30 minutes and sure enough, another Avidia Bank Commercial came on. This time I switched to 2 channel stereo only. When I measured the level at the same distance from the 2 speakers, I obtained between 98 & 103 dB SPL readings.

The interesting conclusion: It looks like a sneaky way to up the commercial volume for some folks surround sound systems, because you have 5 speakers to produce the louder appearing sound as opposed to folks with just 2 channel stereos. In reality it gives you a
2 ½ times louder volume by using all 5 speakers as opposed to just 2 speakers.

Anyone else notice this?

I see it lots of places. Technically it is something the network should fix, but I see it on lots of SD programming on HD stations and all the .2 channels in this area.

What you are seeing is signal within the "vertical blanking interval". The VBI signal is a data signal contained within the regions of Line 21 & 22 analog.
A lot of times, when a program is "upconverted" from an older analog tape, the device which does the upconversion, won't mask this, and with the higher resolution, it's much more obvious. Typically what i've seen isn't CC data (Line 21 field 1), but rather time code. Back in the ancient days of analog broadcasting, (wait that was only a couple years ago, right?), anyways, we used to stuff other things in the VBI too, including color bars, test pulses, etc., in the lines below 21.

Only Channel 42 & 30 are providing PSIP info to do mapping to the Analog equivalent (7 & 4, respectively) channels. ABC 20 & FOX 32 never have. If the Panasonic does mapping of non-PSIP channels (like the newer Hughes/Tosh/Mits does) then it sounds like something giot reset in the advanced programming guide.

Do you mean WCVB on channel 20 and WFXT on channel 31? (not 32)

Hi All,
Been looking at ditching Comcast and going with Antennas Direct DB4e antenna. I understand this is a UHF antenna only, but it appears there are not many VHF channels to really have to worry about it.
It comes highly recommended from some of the members over at the TVFool forum.

Here is my TVFool report and was wondering if anyone here might recommend something else or has any experience with this antenna.
Ill be trying to locate it inside the house in an unoccupied 3rd floor room with slanted ceilings. If the need requires, i may locate it outside.
TVFool Report

Im going to feed a Homerun HDHR3-US tuner that im itching to pull the trigger on.
post #10256 of 10626
too-loud-laugher, you have a good plan there. i am at similar azimuth plus 20 miles from the needham xmitters and use uhf antenna inside attic, plus a winegard uhf preamp. i'm looking for another sort of 8VSB & clear-QAM tuner too, like some sortof hd-homerun...

Well, someone at WBZ must be either watching here or they noticed the Avidia Bank commercials were running the surround sound at full bore! The last couple days, they sound normal and only using 2 channel sound for the Avidia Bank commercials, the same level as all others. The spots are the same ones that used to use all 5 surround channels.

I usually listen to the early morning newscast while preparing breakfast between 5:00 and 7:00am from the kitchen which is next to my living room where I have the TV running. When all 5 channels came on, you could easily hear the increase in volume form anywhere in the house, not just adjacent rooms.

Well, I must have spoken too soon. This morning, the first Adidia Bank commercial was the loudest I've heard in some time. It actually caused a picture to vibrate on the wall in the next room. UNREAL!

Anybody know what's up with channel 56, the CW tonight? It appears to be out on both my FIOS feed and my antenna feed.
post #10260 of 10626
The Ch 56 OTA signal is down at 10 PM, however they are up on Comcast cable in Boston, which most likely has a direct feed.
