Jacksonville, FL - HDTV - Page 114

the physical channel for WJXT HD that comcast is sending the signal on is RF117.
the 1-1 is virtual channel info also being transmitted by comcast. your tuner is going to RF117 WJXT HD and then displaying the virtual channel info that comcast is sending, but your tuner is actually tuned to a sub channel of RF117.

the reason we are seeing the same virtual channel numbers for multiple stations is comcast is now using the same main virtual channel number (1) for each of the four RF channels (70, 113, 114, 117) that comcast is using to transmit the local unencrypted broadcast stations. each of those RF channels has sub channels so, those subchannel numbers are the second number in the virtual channel number. so, for RF70 we see 1-1, 1-2,1-3,1-4 and 1-6: for Rf113 we see 1-1,1-2,1-3; for RF114 we see 1-1,1-2,1-3; and for RF117 we see 1-1,1-3.

your digital tuner firmware determines how this virtual channel info is displayed.

Can anyone supply a current scan of the in-the-clear QAM that is available right now?

Thanks in advance...

I called comcast and they are very aware of the ABC-HD problem.

They are blaming it on the station, or at least they are telling the CSRs to say that.

acribb, the list in post #1 is correct except for the recent switches in the local's frequencies.

I don't think that the following, listed on page 1 as HD QAM channels work, at least for me. Can anyone confirm?

71-2 DSCHD
75.1 TNT HD
102.1 ESPN HD
103.1 INHD
103.2. HD PPV

Adam,

I have ESPN at 111-5 (Not HD)
ESPN2 at 111-3 (Not HD)
TNT at 77.5

Not sure what those others are...

-Bob

Probably need someone who subscribes to something other than basic service (like me) to verify if those other stations have their HD counterparts one the channels listed.

It really doesn't matter where ESPNHD is since it's encrypted. And everybody gets the same QAM signals on the wire no matter what package you subscribe to.

Ok people, here's the scoop -

DISC HD - 101.3
TNT HD - encrypted
ESPN HD - encrypted
HGTV HD - was on 71.1, now encrypted
INHD - encrypted

Please update the front page with this current information.

If anyone finds any other unencrypted QAM channels, please let the forum know.

I think HGTV HD moved to 108-3, as per the post about a page or so ago.

Three new HD channels added on Comcast:

Channel 444 Abc Family HD
Channel 445 Disney Channel HD
Channel 446 Science Channel HD

Anyone else having problems with 47 OTA? For the last couple days it has been breaking up pretty regularly and all the signal strength meters show about a 15% reduction in signal strength. All the other channels are the same as they were. Any ideas?

So, pardon me if this has been asked 100 times already but...

If a channel is unencrypted, I should be able to tune it in with my QAM tuner as long as I have basic cable from Comcast?

In theory, yes. It doesn't matter what level of service you subscribe to.

Our QAM channels go from ch69 (495Mhz) to ch116 (747Mhz). But some tuners have problems with some frequencies.

Fox HD is no longer 1-2, does anyone know the new QAM channel?

I'm in the Arlington area and for the last couple of days almost all the local HD stations have been breaking up or temporarily disappearing. Right now I'm getting Fox on 113-2 without it automatically flipping over to 1.2 as usual and ABC is now 70.5 instead of 70.6...but this may only be temporary. I'm close to the transmitters so I also use rabbit ears for OTA and they're coming in perfect so I'm blaming Comcast.

Mine is now on 113.2

Reaper and Smallville on OTA 17-1 were in stretched SD this week. I just called the station to see what the problem was with their HD feed from the network and was told they weren't aware of any problems. She also said I was the first person to call in to inquire.

I guess we don't have many Reaper or Smallville fans here???

thanks for the help!

I am getting the following for the last few days:

1-1 TV-4 (also access from 117)
1-1 CBS TV-47 (also access from 114)
1-1 WJCT (also access from 70)
1-1 WB (also access from 113)
1-2 TV 12 NBC
1-2 WJCT Create
1-3 LATN
1-3 Weather Plus TV-12
1-3 Blank (no error just blank screen)
1-4 Florida Channel
1-6 ABC TV-25 (HD)

I cannot locate a HD channel for FOX that works for me, I am on the Westside and 113-2 doesn't work for me.

Hope i did this right. i live 25 miles from WJXX antenna. i can recieve all local digital channels through my OTA antenne except ABC 25.1. I have called the station and they say they are broadcasting it. Called Dishnetwork and they say its not their problem. I was just curious to see if anybody else cant recieve 25.1 through their OTA antenna??.

If you are getting 12.1 (NBC), you should also be getting 25.1 (ABC). Both are VHF stations (13.1 and 10.1). You might try tweaking the antenna. Sometimes the difference between receiving a digital station is as small as an inch or two (or less) one way or the other. I know that from experience.

i have tried everything, but i dont get 12.1 either. fox 30.1 is crystal clear. used antennaweb.org to find direction antenna should be etc. i live in Lake Asbury area orange park/middleburg

I'm trying to watch the Cavs game on ABC, but it's not on channel 1.6 anymore. Anyone know where it moved to?

70.6... found it

I live at the beach and get OTA through an antenna and also have Dish. They're right, it's not their problem. You can get 12 and 25 through Dish's sd locals, but the picture stinks compared to hd.

Both 12 and 25 are problems. Peter is correct, start by trying to reaim the antenna. It may also help if you use a powered/amplified antenna. If the antenna is only slightly off the perfect line, it can affect reception. Try aiming the antenna so that you get the best signal on 12 and 25 and the rest of the channels should be ok.

I also think that cabling has an effect. I run the antenna to a number of tvs and the two with the shortest cable runs don't have the problems the ones with longer runs do. I also suggest that you make sure the antenna cable is RG-6, preferably quadshield, that is rated for 2300 MHz. HD signals require a higher bandwidth than regular digital signals.

The same is true for splitters. Every splitter results in some percentage of signal loss. Use a high quality/low loss splitter. You might also try a powered splitter(Radio Shack) that has an adjustable gain.

Assuming your tv has an HD tuner and is not just a monitor, try connecting the antenna directly to the tv as an alternative, or in addition to, the connection to the satellite receiver. I have both vip622 and 211 receivers and the OTA tuners are nowhere near as good as the ones in the older 811 series. Your tv may have a better tuner.

Finally, I assume you have the antenna lead first connected to a surge protector before it goes to any equipment. Although I have no proof, I expect that there may be a difference between budget devices and more costly units in the ability to pass unaffected signals.

The overall goal is to minimize signal loss everywhere in the signal path.

I hope that something here helps. Good luck. I know this is frustrating. Ward

ward, thanks. i run the antenna (Terk) strait to my Sony Bravia XBR 46" LCD. its just so weird to pick up Fox 30.1 crystal clear when 25 and 12 are in the same direction and same distance. no matter what position i put the antenna in i barely get any reception on 25 and 12. i was hoping to find someone out my way that has same problem before i go buy a more expensive antenna

Terk antennas are junk.

Is your antenna a UHF only antenna or does it handle VHF as well? I'd think you could use the analog signal of WTLV to gauge how your signal is...

- Trip

What kind of Terk antenna is it? Indoor or outdoor? Is it that square design or one of the plastic models that is a straight bar? Sorry, I don't know model numbers. Where is it mounted?

In the middle of the night, the QAMs were remapped again.

pbs 70-1,2,3,4
abc 70-6
CW 114-1
fox 114-2
cbs 115-1
nbc 115-2

I sometimes wonder if this is all really necessary.....or just done to be annoying.
