Nashville, TN - OTA - Page 4

post #91 of 3508
I emailed FOX-17, and here was their response:

Mike, as of Monday 09/13/04, WZTV-DT channel 15 is off the air with antenna problems. It was on until Monday morning, so you should have seen it prior to that and should be able to see it when we return to the air (hopefully sometime this week).
Thanks for writing,
Gibson

I am a new HD OTA user (started Sunday), so I am glad there a thread here for Nashville OTA issues.

I live in the Percy Priest Lake area (southeast), and I can get all of the digital channels with an indoor Silver Sensor antenna.

Welcome aboard!

Write them back and ask them when they are going to increase the power I live in Hermitage and had to use an outdoor antenna (CM 4 bowtie) to get low-power 8 and 17. Full power 2 and 5 came in fine in my basement on a back-of-set single bowtie. I made a wire dipole for channel 4, since their VHF digital singal did not come in too good on my UHF antenna.

Thanks for the welcome.

I will see what I can do about your request, dwynee.

Let me also suggest that you (all of you) contact MisterDTV (the Sinclair executive) and let him know that we need more power on WZTV. It's in Sinclair's hands.

Any update as to antenna problems at WZTV?
Sunday's not far off.
Thanks to Panther for getting this thread organized.

Channel 17 has been on a couple of times this afternoon with increased power.
post #98 of 3508
Today I called WB58 (WNAB-DT) about when they'd be broadcasting OTA in HD. They said no specific date, but they were working on it and expected to be broadcasting HD OTA by end of year. That's more-or-less a technical issue.

Re when the various cable and satellite carriers provide WB in HD, that's a combination of technical (bandwidth issues) and non-technical (contractual negotiations).

It's unfortunate since 2/3 of the WBs new shows are in HD, and they're publicizing their upcoming HD broadcast Lord of the Rings in November. I guess better later than never
post #99 of 3508
Jim,
Thanks for the update on 17. Must have missed it yesterday. Can't wait for the increased power.

jdm,
Thanks for the good news on the WB. That should really be something.

I checked last night an they were off the air - or too weak for me to see anything.

They are missing out, as I tend to "try" new shows just because I can Tivo and watch them in HD. NBC's new "Hawaii" for example is an early start new show in HD. The scenery in Hawaii looks nice - the show is not that good, however. But I at least TRIED it since it was in HD.....

The Titans will be on CBS Sunday and the only local Fox game is slated to be the Seahawks at Tampa Bay in a late game. Does not sound like a big loss if we can't see that epic matchup in HD

I suspect that most of the country will see the Titans vs. Colts. That's a marquee matchup.
post #102 of 3508
I am able to get Fox-17 this morning.

But now I can't WB.
post #103 of 3508
I'm getting WZTV too and the signal appears to be much more powerful. Actual reliable daytime reception. Amazing. WNAB is off the air for me too. Must be doing all kinds of work.

Anyway, WZTV is just about perfect. Assuming the increased power stays around.

-Reagan
post #104 of 3508
I wonder if WNAB is getting ready for HD and that's why it's down.
Wouldn't that be nice.
And if that is the reason,UPN should ready to go right behind it.
Aren't all three Sinclair's on the same tower?
post #105 of 3508
Anyone else having trouble pulling in WKRN today? I have been unable to recieve a signal all day.

I didn't have any issues with it today.

Should be in HD. I saw a promo that said the Colts/Titans and Ravens/Steelers would be the early games in HD Sunday on CBS, then the Browns/Cowboys in HD for the late game.

They are. (for digital. Fox analog is on the channel 4 tower.)

I'm not too sure that would result in all three stations going HD at the same time though. The vast majority of the tower site work had to be done to get a digital signal on the air at all; the vast majority of the work to convert from SD digital to HD is done at the studio.

Interesting to see the comments about WZTV's signal improving -- from here, it's looked like they've been at higher power for several weeks.

Can ya'll please share what kind of antenna you are using to pick up WSMV? I've used a bunch and am still having some problems.
post #110 of 3508
WSMV is on the VHF spectrum (channel 10), so that's probably the cause of your problems. There are some combo antennas out there that will pick up VHF and UHF. I can pick up that station with a particular UHF antenna, but not with several others. The one that works for me is a Zenith Silver Sensor.

I can get WSMV through a Silver Sensor too. But why does it work? If it is UHF only, how can it pick up VHF signals? I am not complaining, but I am curious.

Well, antennas are really just glorified coathangers. UHF antennas are the right length and size that they pull in the whole UHF spectrum pretty well, but they also capture signals outside of that range. Apparently this design is one that pulls in signals from the high VHF range pretty well.

I'm about 2 mi S of Franklin, and I use a Channel Master 4221 4-bay bow tie UHF antenna mounted in my attic. Feed line is RG-59 and I use a mast-mounted Channel Master Spartan preamp, model 0064DSB. Receiver is a DirecTV HR10-250. I get all local UHF digital channels perfectly, also WSMV-DT, which is VHF high band, channel 10 frequency.

A UHF antenna is certainly not optimal for VHF, but often will work mediocre on VHF high band. For VHF low (channels 2-6) a UHF antenna typically doesn't work very well.

If you have trouble with VHF reception of WSMV-DT and outside mounting is OK, try a larger UHF/VHF combo antenna like a Radio Shack VU-120.

According to www.antennaweb.org, at your location and zip code a medium directional VHF antenna is required for WSMV-DT at your location. However that assumes no major obstructions or other problems.

There are USGS topographic maps you can view on line at www.topozone.com. Find your location and determine your approximate elevation. Scroll S toward Nashville and see if there are any tall hills between you and the station.
post #114 of 3508
I just got a response from the engineer at WZTV. As of last week, they've been broadcasting their digital channel (15) at 1,000kw. So that's a move to HD and full power all in the same week. Not too shabby.

I seldom watch any OTA anymore, but honestly, an old set of rabbit ears that would sell for $10 at Walmart pulls in 2,4,5,8,17,28,30,39,44 and 58 at my place near Hermitage. Funny thing is that the same antenna performs like crap on analog signals....ghosts, snow, interference. It looks very 1950's sitting next to the HD box, but I will hang onto it until Comcast and Sinclair work out their differences.

This is an interesting web site and basically confirmed to me what I already knew. Nashville is at about 444 ft above see level and my house in Bellevue is at about 700-740 ft above sea level. But there is a 800 ft hill in my neighborhood 1/4 mile from my house right on the 29 degree axis between me and CBS, NBC, FOX, UPN and WB. There are 800-900 ft hills near 1-40 and Old Hickory Blvd on or near the same vector.

The first hill I mentioned and nearby hills also are responsible for the terrible cell phone reception we get in this area. Regardless, I hope that something like a 4 or 8 bay Channelmaster can solve this problem. I'd like it to be in the attic, but I think I'm going to need all the gain I can get.

Any piece of electrically conductive material (metal) will pick up TV signals, on any channel. I work for WSMV; when testing a DTV set-top box recently, we just stuffed a paper clip in the antenna jack - and received our own signal just fine. Of course, we were 1500 feet from the transmitting antenna! (though we did pick up three competitors from as far as five miles away...)

The idea of the Silver Sensor (and indeed pretty much every worthwhile UHF antenna) is to connect several antennas together. By carefully arranging the size of these antennas and the connection arrangement, it's possible to cancel out unwanted signals and noise coming in off the sides and back, and reinforce signals coming from the desired direction.

The Silver Sensor is a "log-periodic" design. This means that it works as intended across a range of frequencies, roughly a 2:1 range. This is enough to cover the UHF TV channels, which lie between 470 and 890MHz. (OK, that includes obsolete channels 70-83) Larger log-periodic antennas are used by hams to cover the 14-30MHz shortwave spectrum.

VHF TV is much lower in the spectrum. Channels 2-6 are 54-88MHz; channels 7-13 are 174-216MHz. These frequencies fall well outside the 470-890 range where the Sensor is designed to operate. In fact, no single log-periodic antenna would behave as a log-periodic in any two of these channel ranges.

The Silver Sensor *does* still pick up VHF signals - after all, it *is* a chunk of metal. It just doesn't exhibit the predictable cancellation & reinforcement properties it does for UHF. It will likely pick up interference and noise from other directions. It's also too small to be really efficient at picking up the longer waves of VHF stations. (the length of a radio wave grows with decreasing frequency/channel number; channel 10/200MHz signals are about 1.5m/5' long, while channel 17/500MHz signals are more like 2' long)

w9wi,

Since you work for WSMV, I have a question for you. I was wondering something when WSMV airs HD shows with Dolby Digital 5.1, such as LAX or Las Vegas. Why is it that the dialog of the shows seem to come out of all three of the front speakers and slighty in the rear. It seems that the DD5.1 mix isn't right or something. I noticed this also when the olympics were on. This was not the case when I switched to the Directv NBC-HD feed during the olympics. The dialog came out of the center channel and the other sound effects such as music came out of the left and right channels. The sound is fine when WSMV switches back to Dolby Digital 2.0. It's only on the 5.1 when the dialog of programs doesn't seem to be in the correct channels. I wasn't sure if you could do anything about this or not.

Thanks, w9wi! That was a great explanation.
