I have noticed, just within the past several weeks, that I am now having a very similar issue on many (but not all) shows on the Investigation Discovery channel. The difference is these programs don't have background music/sound effects that have the reverb echo distortion like a cave thing. I can rewind the show and have verified the level of the center channel dialog is in the file (it's not my surround system faltering).
I have the same issue. All of the background sound are too loud and very distorted. I've watched the same shows On Demand and can confirm the On Demand sounds perfect while the signal from KXTV are incredibly distorted. It's been this way for years and I thought it was a problem with my system. I finally compared against On Demand it the difference is night and day.

I've never watched on demand (because I use WMC PC). All I can say is, the audio on KXTV (ABC primetime shows) BITES. It sounds like everything is in an echo chamber or run through a reverb processor.

The audio almost sounds like it's encoded at a very low bit rate. The first time I noticed it was during Revenge. I thought it was deliberate to match the dissonance of the show.

Now I want to watch the series over again to hear what I was missing.

The engineer at KXTV must think that on shows like Castle the background music is more important than the spoken dialog. During these moments I try my best at employing dog ears.

I only have stereo for my TV audio and I haven't had a chance to perform this test on an evening network program, but today on the football game I was able to switch rapidly between KXTV, KGO and KSBW. The audio on KGO and KSBW sounded identical but the KXTV audio sounds like the high frequency response is slightly rolled off. It doesn't have the crispness heard on the other two stations.

I suppose this doesn't mean anything but KXTV is a few seconds ahead in time compared to KGO which is a few seconds ahead of KSBW.

It's gonna be tough doing any kind of test/comparison just using stereo speakers.

I've heard the KXTV audio problems on these prime time shows - Castle, 20/20, Motive, Revenge, What Would You Do, Forever, Agents of Shield.

Never heard problems on local news, Jimmy Kimmel, Good Morning America, (nightly) ABC World News. In fact the Jimmy Kimmel musical acts sound really great.

Only prime time show that doesn't seem to have the audio problem is How to Get Away with Murder.

I've tried bringing this up in a National ABC topic but it always gets dismissed or ignored...

What happened?

Edit: Back to the main antenna at 8:30 am.
Chuck,

We lost two of our three amplifiers at the main site. Switched to the backup. Sorry, late in reading this.

I have a DirecTV HR20-700, and I can no longer pick up the ABC and CBS affiliates in my bedroom TV. I kept getting 721...792 errors.


When I reinstalled the guide these two stations do not know appear in the guide. I still get all the OTA stations in my living room HR20-700.


I know the ABC affiliate must be weak because I often cannot pick it up on my PC's Media Center.


Anyone else have this problem? Recommendations? Thanks!

Hauppauge WinTV-HVR-1265 Tuner Card Provides the Best Fringe Reception

I have been playing with my new Hauppauge WinTV-HVR-1265 single tuner card which has the best tuner sensitivity of any PC ATSC tuner on the market! I have now found its sensitivity is even better than my LG M237WD 23" HDTV/monitor which has been my gold standard for tuner sensitivity....until NOW! The WinTV-HVR-1265 is able to lock onto marginal KCRA signals that my LG M237WD cannot. So now I will be able to watch some KCRA programs at times I would not have been able to due to temperature inversions. It's not a solution for KCRA's overly narrow broadcast antenna beam, but a definite improvement!

The WinTV-HVR-1265 tuner sensitivity beats my LG M237WD HDTV which beats my Hauppauge Aero-m USB tuner which beats the new Hauppauge WinTV-HVR-2255 dual tuner card, in that order. The new WinTV-HVR-1265 replaces the old WinTV-HVR-1250 tuner card. The new WinTV-HVR-2255 replaces the old WinTV-HVR-2250 dual tuner card. They have the latest LG3306A demodulator chip. The WinTV-HVR-2255 has a built-in antenna splitter for the dual tuners which apparently very significantly degrades the tuner sensitivity compared to the WinTV-HVR-1265 single tuner card which has no splitter. If you are looking for a dual PC tuner card and want the best tuner sensitivity, get two WinTV-HVR-1265 cards instead. The difference is BIG! (I bought and quickly returned a WinTV-HVR-2255 dual tuner card after finding its tuner sensitivity unacceptable.)

Are you talking about sensitivity or multipath handling? Tuner sensitivity is pretty much set by its noise figure. If you have a mast mounted preamp tuner noise figure is mostly irrelevant. OTOH, an increase in multipath handling would be a welcome improvement.

No one answered you so I thought I'd at least say something. You're having an OTA issue? Channel 10 is not weak. More information about your antenna and location might be helpful. TV Fool report too.

We are talking about being able to lock onto a lower level signal given the same noise background, i.e. the demodulator of the more sensitive tuner is able decode a signal in a low signal to noise ratio situation while the demodulator of the less sensitive tuner is unable decode the same signal. Multipath may or may not be a part of the "noise". It's just one form of interference.

Regardless, just accept the fact that a tuner that locks onto a signal that another tuner is unable to lock on is considered to be more sensitive by just about any normal person.

Retro TV/Heartland and Jewelery TV coming to Sac again.

Within 2-3 weeks KBTV-CD is adding Retro TV and Heartland TV along with Jewelry TV. We will have 7 streams soon. Wizebuys (infomercials on 8.5 is making an exit.) Jewelry TV may be delayed as we need to install a 3.7m C band dish to pick up that network.


Mako, LLC has a mux on G19 for some of the networks that we carry. Luken is providing their networks on the G19 KU mux for us.

Well, things change.. 8.2 is a no go for Jewelry TV because we cannot install a 3.7m dish at our transmitter location.


BUT 8.5 and 8.7 will be RETRO and HEARTLAND soon. We have some test video up on 8.7 now (SBN feed) no audio right now. 8.2 will disappear sometime this week.

Since switching to RF 27 KBTV has had a reliable signal even though it only runs about SNR 20 dB. It's rare for me to point over there and not see it.
