"Oregon Naturally" was supposed to be on at 10:00, so I missed at least two good HD shows yesterday. Oh well, OPB-DT is pretty good about re-running shows.

I was so pumped that just redirecting my antenna allowed me to pick up 10-1 (OPB), and then I encountered audio drop-outs and picture hiccups about every 30 seconds yesterday (Monday Jan 6 about 10PM) just after I said to my wife, "Hey, lookee here at this real nice HDTV picture". After two minutes of being bothered by the sound and picture hiccups she gave up

So maybe it wasn't my antenna? It was OPB? The signal strength meter was the same as my nice and shiny KATU-DT reception.

I sent an e-mail to OPB asking if they have problems, I'll post something when I get a response.

Did anyone watch the show on Spies last night on OPB? Was it HD? I am currently restricted to just watching off Dish till I get my antenna back up. Some scenes like the flying insects looked darn good like they could have come from an HD source. The program was also presented in widescreen format.

Thanks.

Hi,

I lived in Portland/Hillsboro area (SKyline & Cornell Rd to be specific). Looking for an antennae that would help me get HDTV signals. I'm using a TOSHIBA HD DSS. I can get weak KGW and OPB DT signals with the Channel Master Stealth antennae but looking to get KATU also.

I can't find the Radio Shack double bowtie antennae anywhere. A friend of mine showed me this antennae and I could get 90+ signal strength at my house.

I also can't locate the Allegro UHF 4149 double bowtie.

Could anyone tell me what I need? Really want to watch the superbowl in HD

thanks

HIeu

Don't know if this is what you are looking for, but.....I bought a big 'ol Channel Master VHF/UHF from Fry's in Wilsonville for $49. The prongs slope down and out from the center-shaft so I was able to mount it on the peak of my roof on a 1.5' mast and all of the off-shoots hug the slope of the roof on either side (does that make sense?). The result was a big, huge antenna on my roof that is NOT visible from the street or my backyard. You would never know its there unless you climbed onto the roof. I get very good reception of all of the local digital stations.

You're very close to the towers, which can present unique problems. First off, you're getting your signals from different directions. Also, you can get some pretty strong multipath interference.

Antennaweb shows the digital stations in red - a medium directional. I find this rather surprising, given your distance and the fact that the signals come from between 119° and 150°.

I'm a few miles further away (same zip code), and the towers are within a couple degrees of each other (according to antennaweb). I first tried that Stealthtenna; what a piece of junk. I was going to put it in the attic but I got a fairly strong signal in the house (couldn't get KATU). I replaced it with a much smaller Silver Sensor from Circuit City. The signal was much stronger, and KATU came in great.

I would recommend a Silver Sensor to just about anyone who isn't too far away and doesn't need multi-directional. CC is good about returns so there's little risk. Its a highly directional antenna, which might help some with the interference - but it makes a difference which way you point it. Best is probably between 120° & 130°, and hope for the best with KPDX & KPTV (137° & 150°). Point it out a window for best results; don't just aim it at a wall!

If you have a strong signal but dropouts, you may be experiencing multipath and need to get an attenuator.

IIRC, it wasn't HD. I've been having so many problems getting OPB-DT reliably the past few days (seems others have as well), that I haven't been watching it except to check in from time to time to see if its better.

post #338 of 8664
Oh my... KATU (ABC) 2.1's HDTV video and audio is coming in great tonight on my SIR-T150. First time I've been able to watch KATU in about a month. DD5.1 is being received great!

post #339 of 8664
Well, all was good until the Bachelorette came on. Then the audio went back to the garbled, unintelligible mess.

Oh, well.

Erik

(And yes, my OPB video is very choppy too.)
post #340 of 8664
thanks BDB & TMBUTCH,

I'll try looking at those suggested antennae's. Hopefully, I can get this resolved by Super Bowl Time.

Is anyone getting good signals from OPB-DT? Its been cutting out for several days now.

GOT SIGNALS with SILVER SENSOR ANTENNAE
OK, finally pick up the Silver Sensor Antennae from Circuit City. Good signals with KGW-DT and OBP-DT (fluctuate between 50-100 probably because of the wind? but get 100! for some moments). Even get KPTV-DT and KPDX-DT if I move it around carefully. However, I only get 60 for KATU-DT and < 20 for KOIN-DT. What can I do to increase the signals? A powered amplifier? Which one?


BTW, I had to point my antennae at about 100 degrees CCW from where I get good KGW-DT signal in order to get KATU-DT. Weird, considering the locations indicated by "antennaeweb" aren't that far apart.

Anyhow, I guess I just need to go find an signal amplifier now

Thanks ahead for any more tips

It sounds like you are buried in the trees. That would explain the wild fluctuations. You probably also don't have very good line of sight. Use UHF analog 24 and 49 as aiming aids for KOIN/KATU and KPTV/KPDX respectively. Adjust the antenna for the least amount of ghosting. KGW and KOPB should be in between the two.

Only if the analog stations are VERY snowy, indicating low signal levels, would an amplifier help, otherwise it will most likely hurt your reception.

I had to call KOIN master control this afternoon because they hadn't switched modes to give all the bandwidth to the HD feed on the football game. They got it fixed, but she was surprised that it wasn't right. Don't they have monitors to look at the different sub-channels and see for themselves that things are not right?
Thanks for giving us the best HD signal possible.
post #345 of 8664
Thanks for making that call!

I noticed the picture was lousy with pixelation at the start but then got much much better. I thought it was Lee calling in but I guess it was you, foelker.
post #346 of 8664
So how much range does one feel that a Silver Sensor is good for? 20-30miles more, less?

AS I posted in the CBS AFC Playoff thread... The button was pushed, but the switch-over didn't happen due to a software problem.

The monitoring Master Control has is two NTSC monitors fed by DTC-100s with 6-1 and 6-2 and a larger HD professional monitor (out of line of sight) on 6-1 or previewing the incoming network feed. When transmission modes are switched sometimes the DTC-100's drop back to 6-1 (which is what the standard says should happen) or the 6-2 tuner will just freeze up. None of this is 100% effective, but it is the 'best' technology available.

The ATSC Encoder control software isn't much better. It is two year old 'beta' software that cannot be upgraded because they have changed the hardware and it would be a six-figure cost to upgrade our hardware (original cost $350,000) so we could use newer software. So we are pretty much stuck with what we have for some time. Once Master Control got a hold of me (I was not at home for the start of the game) we walked through re-starting the control program several times until the mode switch took.

This is difficult to answer because it depends a lot on what the antenna is shooting through. Since it is an indoor antenna it has the signal loss of at least one wall, maybe more, at roughly 10 db per wall, more walls, more dbs lost. Then it is likely to be below nearby obstructions that roof-top antennas would see over. Under 'normal' indoor circumstances I would expect the Silver Sensor to work very well from 2 to 10 miles out, dependant on obstruction attenuation from 10 to 20 miles out, and in need of a good amplifier beyond 20 miles unless it is high up with clear line of sight. Your results WILL vary.

Hey Lee, caught the end of the Sat game (so I missed the bandwidth snafu) and all of yesterday's game. Just wanted to say thanks for all the work you guys do holding the patchwork equipment set up together for us. I for one, really appreciate it. It would be nice if you guys could swing for a new set up but understand the economic realities of the situation. Raiders/Jets yesterday was truely a thing of beauty.

Now for the bad part (not you Lee ). Is everyone else still seeing the horrible strobing on the Fox widescreen games? After reading the Fox thread in the HD forum it seems that it must be way worse here than in other places since many said their feed was good. It's so bad for me I just have to watch the SD feed. It's a drag having to go to 4:3 but at least it's solid and it's not like the PQ is a huge drop off from the ED. I was thinking of getting ahold of Ed but wanted to check with others to make sure it's not just me before bugging him. On my set up it's terrible... What are you guys seeing?

Hello all,

I'm new to the area and just got my HD200 and 50" plasma up and running a couple of weeks ago.

I watched all the playoff games over the weekend with my girlfriend and have to say that the CBS feeds were TREMENDOUS - especially the Raider game as the light changed and you could the stadium lights take effect on the players/field.

I didn't see any significant strobing on the Fox feeds, but my girlfriend (completely unaware of the differences) commented that the Raider game "looked so much clearer" than the 49er game.

I'm very impressed that Lee pays attention to this thread...I'm even more of a loyal fan of KOIN as a result.

Thank you all for a great thread with valuable reading!

OPB seems to be behaving better, at least last night during the Antarctica Ice program. Anyone see this? It was incredible. There were still a few breakups but all in all pretty solid. It shows again 8PM Thursday.

Also, does anyone know if the "River of Iron" show Tuesday night is in HD?

Thanks.
post #352 of 8664
R11 -

Yes, the strobing on FOX widescreen is still just as apparent for me - makes it unwatchable. I have to switch to 30-1 and stretch it. It must be a local issue. Also, seems to me that at the beginning of this season, it wasn't there. I thought I can recall watching a FOX widescreen game earlier this year and noting that the PQ was relatively nice (yet still garbage next to CBS HD).
post #353 of 8664
I have to agree, that Antarctica (Nature) program was awesome! I remember thinking to myself how glad I was that OPB was working during that (most of the time). I did notice a few dropouts, and I noticed that the OBP logo didn't go away during the dropouts - kind of rules out a reception problem!

The Fox games looked OK to me also. I get Fox really well over here in the Bethany area. I know the station's only a couple of miles away, but the transmitters are on the same towers are other channels, so I dunno.

post #354 of 8664
R11, FOX is so bad, I watch it on my 27" TV downconverted NTSC. I can't stand crappy looking TV. I did the same thing for the CBS game on Saturday because the pixelation was so bad. I must not have noticed it got better or I would have switched back to the big screen.

Oh, well, Sunday was much better.
post #355 of 8664
Hmmmm, now I'm not sure what to think then. I wonder if it may be compatibility issues with certain setups making it look even worse maybe? If anybody had to watch what I've been seeing (and TMBUTCH as well from the sound of it), there's no way they'd call it "OK". It's worse than crappy . I think I will drop Ed a line and see if he's got any feedback from others in the area.

post #356 of 8664
When I can tune in FOX, it looks fine. My problem is I suffer from severe video and audio drop outs which make it unwatchable. My signal strength with FOX is as strong as all other stations but will just drop to 0 and then come right back and be perfect. Couldn't watch either football game. CBS was GREAT. Thnx Lee!
post #357 of 8664
Has anyone else had problems timeshifting KOIN HD programming. I was unable to record either AFC playoff game this weekend and last night my recorder showed an error message relating to copy protection. I am using a Samsung T165 and a Mits HS-HD2000U connected via firewire. I am aware of several issues with the T165 but, I don't seem to have the same problems recording other OTA network programming.

I think you're probably right about an equipment related problem. I have a Toshiba receiver and I haven't EVER noticed a problem with FOX. Last weekend's games were definitely better than SD with sharp details.
post #359 of 8664
R11 - we may have discussed this earlier, but I am getting HD through a Dish 6000. FOX is the ONLY channel that has this strobing/bleeding effect. It must have something to do with their "enhanced definition" signal and how my hardward converts it.
