Has anyone noticed that KFLA has shifted the programming on its sub channels? MBN HD is on 8.1 and RTV is on 8.2 now.

Yeah, 8.1 is now broadcasting a Korean network. They are not actually in HD though. KFLA 10.5 station's website is havastv.com which I think is Arabic.

Dur...feel dumb now. Thank you. haha

havastv.com is Persian not Arabic.

KFLA is a mess. They need to sort out their issues before DVR enthusiasts can get a dependable guide for recording.

My Tivo shows the programming info for 8-1 on the old frequency (52?). But that's useless as there is no signal. I did a channel scan and got duplicate channels for KFLA (using the current frequency, 8). No guide info, but there is a signal.

True, I don't get any guide info on KFLA when I bypass my tivo (and hook the antenna directly to my tv), but I thought maybe that was due to a weak signal. Dunno. As for the Tivo, since they still have the programming info on the old frequency, there's no reason they don't have it for the current frequency KFLA is using.

So I'm thinking it's Tivo's fault. I'm thinking we're just waiting for them to notice the frequency change and to make the necessary mapping fixes or whatever.

Well yesterday I hear a 1KHZ tone on 18.10. Any idea
what this will be? Also, wasn't KCOP supposed to be
running BounceTV by now?

Has anyone else experienced reception problems since the beginning of the new year.

Now when I scan I can barely get 25-30 channels. Before the new year I could get 50-80 channels.

Also, now I get multiply listings for the same channel. For example, I'll get 7.1,7.1,7.1 listed 5 times. And I can't even get channel 50.1(socal pbs), 44.1, and 18.1 or any of the sub-channels.

I could never get channels 7.1,8.1,9.1,11.1,13.1 but I was fine with that. Now I'm having problems with the UHF channels to.

Can someone please explain to me what's going on? All I have on my tv is an antenna and that's it. No tivo or anything else.

Thanks

Does it happen with other TVs/tuners?

The signal for channel 25 has been strong here for the past week or so. Previously I could pick up a weeak signal, but never lock in a picture. Looks like HSN & duplicate subchannels.

Same here as of last week.

No, I only have one tv in the house.

Oh, and I forgot to add channels keep disappearing.

Sigh!!

Maybe it is broken. Try another one with a borrowed tuner/TV.

I concur. shoogy: This definitely seems to be a malfunction, and you should get your TV checked out. Hopefully it is still under warranty. Also, your inability to receive the VHF channels may be due to your antenna being inadequate for picking up VHF frequencies. You may need to obtain a more suitable antenna, or at least to try a new antenna location.

I did a rescan recently on my Pioneer set, and am now am able to pick up KFLA, although only intermittently. I find that it usually either comes in pirfectly, or else not at all. The breakdown seems to be about 40% of the time the former, and 60% the latter. This is evidently due to changing weather conditions. The RTV and TUFF-TV subchannels do seem to have some interesting programming, at times. But they definitely need to improve their signal, either by increasing transmitter power, improving their antenna, its location or all of the above.

I just ran a new TVFool signal analysis, and found that KFLA is blocked by terrain ("1Edge"). This is likely to be the problem with its signal here. However, I also get this same designation for KTTV 11.1 and KCOP 13.1, and yet I never have any problem with their signals; they are always very strong here. In any case, KFLA needs either to get its antenna out of the hole, or else substantially increase its power if they want to have reliable coverage to the west.

KFLA is LOS for me, but it does break up periodically.
For some reason it seems stronger in the evenings, then in the daytime.

I have noticed that KFMB channel 8 from San Diego has been a lot worse then usual since KFLA went back to RF8. I pick it up on a different antenna & don't really watch it much anyways, since most of the shows are the same as channel 2 CBS.

Does your TvFool results for KFLA show an 'a' next to it? If so, KFLA may be affected by adjacent channel interferences from KABC and KCAL which are very strong relative to KFLA. TvFool explains what this interference is all about.

Already maxed out.


Pattern is as permissive as would be permitted by the FCC.


It's on the KCBS (TV-2/DT-60/FM, not DT-43) tower on Mount Wilson.

KTTV amd KCOP are full power stations with over 100,000 watts. KFLA is a low power station with only 3,000 watts. That should explain why KTTV and KCOP are much easier to receive.

I noticed better signals from them. Did KABC also get full power recently like a couple months ago?

Thank you for the clarifications.

By "maxed out" I assume you mean that it is running the maximum power currently granted to them by the FCC.

What in the world is a "permissive" radiation pattern?

If their antenna is mounted on the KCBS tower, it must be awfully far down on the tower, because TVFool shows KCBS as LOS (line-of-sight) whereas KFLA is not (1Edge).

Yes, there is an "a" next to it, as well as other "problem" stations, like KTBN and KLCS. But I doubt that this is the main problem, since none of these stations is line-of-sight at my location.

Don't know why you say it's not LOS so it doesn't affect me. It's the relative received signal strengths. Here is TVFools explanation:

Adjacent channel interference has more to do with your receiver. Some tuners are built with very poor adjacent channel rejection. That means that if you are trying to watch a weak channel with a very strong signal on an adjacent channel, the tuner can't pick out the weaker channel because the strong one is drowning it out. Most receivers have good adjacent channel rejection and are not very susceptible to this kind of problem, but in case you do have this problem, a warning indicator is placed next to channels at risk of having this kind of interference.

It has been my experience also that KFLA is stronger in the evenings. Interestingly though, it has been coming in nearly perfectly nonstop for the last couple of days, day and night.

KFMB often puts in a strong signal during the summer here, but I seldom see it during the winter. But I am much farther away here (124.2 miles), and need the right atmospheric conditions for long distance propagation. It will be interesting to see what will happen next summer when both stations are coming in.

The FCC limit is 3 kW for any low-power digital VHF station. KFLA is at 3 kW. Hence, "maxed out."


KFLA is required to protect KFMB in San Diego. They are using the antenna that allows them as much signal toward KFMB as possible, which is virtually zero.


As I said, it's the former KCBS-TV/DT and current KCBS-FM tower, not the current KCBS-TV/KCAL tower. That said, it is about a third of the way up the tower. I suspect going any higher would require a further reduction in power to protect KFMB.

Thank you for all of the clarifications.

I believe I may still have some old TVFool data for my location taken before the transition, when KCBS was transmitting on ch. 60. In any case, I am pretty sure it was LOS then as well. But if KFLA's antenna was only about a third of the way up the tower, the signal probably would be blocked by terrain in this direction, just as I was saying earlier.

That is not what I said. I said, "I doubt that this is the main problem, since none of these stations is line-of-sight at my location." In other words, the signals from these stations are attenuated, sometimes severely, by terrain obstructions. This, I believe, is the main problem.

Also note in your quotation from TVFool:


With high quality equipment and receivers, adjacent channel interference is probably of somewhat secondary importance, but you are perfectly right in raising this as an issue. This is indeed something we need to keep in mind. And this may explain why I do seem at times to see some reception differences between different receivers here in the case of KFLA.

Yeah I've notice since January 1 2012 all these new bizarre stations poping up with redundant programing a possible same ownership and then also flat out most bizarre channel is the Persian 10.5. 10.5 is one of the weirdest channels running very very grainy black and white persian programs from the 1950 to 1970's with vhs tape slp video quality ? With a Persian script ticker running across the top and some English script running along the bottom talking about free advertising quite bizarre. Yes 8.1 (now korean) and 8.2 (new rtv) are still mixed up with my tivo guide. In the past I've gone to the RTV website and email to Roy Mayhugh RTV's trouble shooter and get a eta on when they would get the crossup fixed but so far no word from Roy . It's amazing how many new channels have pop up since January 1. Whats wierd too is how 10.1 and 30.2 are showing almost the same kids programing and 10.4 and 56.3 show similar retro tv shows? LOL . It blows every time I try to update my tivo guide it's addition five minutes on the channel skip screen to delete all the new nonsense channels it just discovered LOL.

Retro shows on 10.4?

I don't get why I can receive 10.5 just fine, but none of the others (10.1 or 10.4 etc)...
