What if my main go is to pick up KGAN since it's not offered through Mediacom?
post #332 of 4949
Since they're a UHF DT (51) you'd have to use a UHF antenna to pick 'em up.

Speaking of antennas:
I have had CM 4 bay antenna for many years with no problems. This summer I had many problems with KWWL OTA. Some days there; some days nothing. I think I have a problem with a neighbor's tree. I was thinking of getting a pre-amp to boost signal for this year. I have DirecTV. Can and where do I put the preamp. I have a the dishes coming into a huge splitter (provided by DTV). Any recommendations for a pre-amp and how to install. I think the problem will just get worse.
post #334 of 4949
A preamp (not amp) has a weather proof housing that mounts near the antenna. You connect the antenna to that and then your normal coax run into the house goes from there. The powered box goes inside that you run your feed into and then from there to the TV. This box is powered of course and feeds the power thru the coax to the outside unit where the amplification actually is taken place, thus called PRE-amp.

Your DirectTv stuff should not come into play unless they've ran your feed thru their splitter.

ChannelMaster is well known for their preamps. I have 2 "CM7777"s.

KCRG & KFXA via Mediacom in Iowa City are breaking up big time tonight.
post #336 of 4949
1st time getting QC locals, amazing, I have a hard enough time getting CR locals.

Picking up 4.1 and 2, 6.1 and 2, 18.1 and 2 (18.2 carrying Cards game, comes in better than 20.1!)...getting a couple analogs too.

Looks like it's time to get a CM 4228 and a pre-amp, have 2 sets of locals...

Bag - that's great!....where in NE Iowa are you exactly?
post #338 of 4949
Don't get your hopes up too high. You are experiencing the effects of the right atmospheric conditions for receiving stations faurther away. I was picking up some Des Moines stations yesterday morning for a while.

I routinely get the QC stations in the evenings, especially in the Summer, but not realiable enough that I would tell you to go out and buy all that equipment. Don't get me wrong, it's good equipment and will help, but don't think you're going to pick them up all the time just cause you got them once or twice.

P.S. You'll probably get them again this morning as I'm getting 8.1 and 18.1 on the back side off my antenna fairly well.
post #339 of 4949
Near the intersection of 380 and 30...

Got them last night as well. Nothing this morning, though, which surprised me.

I thought it might be good tropospheric conditions causing this.

It's just nice to know my Radio Shack antenna, cost me $70 about 5 years ago, VHF/UHF...the main spar is warped slightly downward (very shallow upsidedown U) on the ends because of age, is doing the job. I know I can do better with a better antenna.

Just curious...I've noticed KWWL is suddenly coming in much better lately. From about April through mid-July, it was the most tempermental station of the CR locals I've got. Now, there's a 30 degree window where it comes in rock solid no matter where I aim it at...something change up there I don't know about?

I was hoping I'd have another set of locals for football this fall, but I take it QC locals in CR would never come in here in CR during daylight no matter how good the antenna/amp combo is, right?

Last question. I gotta have VHF on an antenna because of KCRG-DT, right? It broadcasts over 9-1, not 52-1, correct? Reason I asked is I noticed all the QC locals are UHF.

Until the channel re-assignments...then WHBF goes from 58-1 to 4-1.

No, KCRG-DT is on RF channel 52. They will return to channel 9 when analog goes away, as will KWWL-DT. KGAN-DT will stay on 51 and KRIN-DT will remain on 35.

If I were going to install an antenna I would probably do a V/U antenna now rather than put up a UHF antenna now and have to swap it out in a few years.
post #342 of 4949
Boy, that 4.1 sure does come in good though...was pulling in the 90's some last night. 6.1 and 8.1 were somewhat weaker but still pretty solid. They all were more consistant than 20.1, but that's hampster power from what I remember.

Might just try the pre-amp...I got an old fashioned signal amplifier that seems to do pretty good work, but I got 75 feet of rg6 before it gets to the amp, so I know an in-line pre-amp at the antenna has got to do better. Prolly would eliminate some of the momentary lapses of signal I seem to get still.
post #343 of 4949
Weather conditions will amaze you. I've had times that the QC stations peg at 100%.

Preamp was well worth the money in my opinion. I have one on my static attic antenna and my outside rotor antenna.

I am VERY near your location. Don't count on the QC stations for football. I can usually get them in/out for a while in the Winter months, but that usually goes away about the time that games start. Certainly worth trying, but don't count on it.

Hello,

I live just north of IC on HWY1- I am able to pick up all QC and CR stations clear using a CM 4228 (8 Bow Tie) pointed to the QC and a 4224 (4 Bow Tie) pointed toward CR. Both are connected via a combiner to a CM Pre-amp. The anntenna's are both on the roof of a 2-story house with a lot of mature trees blocking line-of-sight.

I struggled with solid QC reception untill the installation of the pre-amp. I have the benifit of being 40 miles from the CR towers and 50 miles from the QC but most people in CR should be able to pick up the QC with this setup. Also, I shortened the cable run from 125 to 75' which also helped a great deal.

Question: I have the Antennas back-to-back on a single mast? Is this a problem?

Not if it's working! Combining 2 antennas like that usually doesn't work as they tend to somewhat cancel each other out. Hey... Congrats if it works for you.

Could it be something as simple as not changing their inputs, and running what used to be HD, but is now SD?

Different topic - getting HD over QAM in cf, over CFU. Has anyone else been getting wholesale breakups? Has been virtually unwatchable - OTA is fine on other receiver, but getting freezes, breakups, and macroblocking, as well as "insufficient signal" thru what used to be perfectly good QAM cable.

I may be out of my league here (and forgive me if I am) - but when you say you swtiched from 28-2 to 28-1, what exactly do you mean? I am with MediaCom and have a Motorola DCT6200 HD DVR STB. I only have channel 828 for KFXA-DT - am I missing something here?
post #348 of 4949
KFXA is only on 828 on Mediacom and it is the HD feed.

KFXA-HD is on RF 27.2 & 27.1 is SD.

KFXA-HD is mapped to 28.1 virtual channel and 28.2 for SD. The HD has never been on virtual 28.2 that I have seen since they came up to power with HD.

I guess I really am out of my league - because I don't understand what your answer means!

Are 27.2 and 27.1 only attainable when receiving OTA broadcasts? or do I have to reprogram my Motorola set-top box?

Yes. On Mediacom, there is only one KFXA HD channel (828 in CR) and it is there HD feed. There is nothing to program on a Mediacom box as I understand since they are not capable of receiving OTA signals.

For OTA, KFXA operates on RF channel 27. They send 2 subchannels on this channel..... 27-1 is there 480i SD feed, and 27-2 is the 720p HD feed. The PSIP data contained in these streams SHOULD virtually map them on OTA boxes to the appropriate 28-1 for HD and 28-2 for the SD feeds

Noticed the new look to KCRGs' 9.2 weather subchannel tonight.

Nice look and nothing but local! Blows WeatherPlus away IMO......
post #352 of 4949
gaack - would beg to differ - at least, when I popped in, the radar was in a tiny window. Liked it before - the way it was. With the storms, I wanted to see RADAR. Not Liz Mathis. Very dissappointed to see it go the way of 7-2.
post #353 of 4949
The smaller windowed radar stills beats the heck out of that crappy KWWL radar display.

I notice now that they are replaying the news. Still better than KWWL WeatherPlus, which is a mini Weather Channel to me. Anytime you want to see something, their talking about the weather on the East coast. At least 9.2 is local content.
post #354 of 4949
hd - now that I know you are around again, , are you or anyone else still having audio problems with KGAN-DT? Folks get it thru CFU - qam - the other night, all that came out was a digital hash, would have probably blown out the tweeters if the ht had been on. I admit, I don't watch much of KGAN (the lipsynch drives me buggy), but even that is better than pink noise.

And I WILL be watching again, once football season returns.

Thank you very much for the well-needed explanation - I can now read the rest of the posts here without tilting an eyebrow.

If you ever need cardiac defibrillation explained to you, I'm your man!

I haven't really had any audio problems with OTA KGAN. I did notice the "digital hash" you mentioned a few days ago in the AM timeframe. It was ONLY on 2-1 & not 2-2 and I sent an email to the CE to alert him but I never hear back from him anymore.

Oh BTW.... I've been here the whole time! Just quite around here. I had forgotten about the July 06' deadline for the other stations to be up to full power. I wonder whats happening with KWKB??? Anyone heard?

Well, it was there in the late afternoon - early evening a few days ago also - you are right, it was on 2-1 - I didn't even check 2-2. And it IS quiet. Guess that is good.
post #358 of 4949
If I remember correctly, it seems that Jerry said that you folks had some kind of dynamic bandwidth balancing going on, between 7-1 and your subs. If so, I was only wondering, , is there any chance you could bump up the bandwidth on 7-3 during the times that you only had SD being broadcast on the main channel?

Or is it a case that the Tube feed is of such a low data rate that extra bandwidth wouldn't help? Which I think you and Jerry also mentioned, back when 7-3 was first introduced. I was just watching it the other night, and thought of this - if all you have on is something SD, you probably don't need all the bandwidth for 7-1, and wouldn't it be nice to see 7-3 looking as good? That's all. Thanks for the Tube, even in it's present form. At least one view appreciates it.

(The application is here.)

This is just to get the 1 MW DT signal on the air and has nothing to do with whether it will be HD or not.
