I've had a few times lately where it taken some time to connect to AVS, but I haven't noticed any delay once I'm connected, including page 396. Wonder what's causing the problem.

[QUOTE=SFischer1;32271337]KFSF went off the air ~ 6 AM it appears.

Check Toast0's chart for outages over a hour.

Ew, does that mean they are done, over and out? Was enjoying the movies.

What is this Channel 1 you guys speak of?

Thanks again, Paul

It's unlikely KFSF is off the air for good. Channel 1 is KAXT, a low power station transmitting from Fremont.

Well, I presume that it would require the decoder to somehow handle the INFORMATION correctly, and now they don't handle basic stuff like the anamorphic flag (I assume it's a "flag") always...

And then there's the guys at the stations who don't seem to know how to set up anything correctly without trying a bunch of times at least. When KRON moved they went through about four iterations of 4-3 until they finally settled on what they wanted, but in doing so they revealed that they are actually a wide-screen channel, so they should have settled on 480i 16:9 anamorphic, but NOOOOO, they pillar-box their content. "Decades" channel 5-2 went through the same nonsense and revealed they too are actually broadcasting 16:9 content pillar-boxed to 4:3 for no good reason other than a certain number of TVs never got the memo about respecting the 16:9 anamorphic flag automatically...ALL channels should broadcast in 16:9 in this year of 2015 in my opinion, even my most brain-dead TV can be set to automatically expand anamorphic screen sizes for all 480i channels, most do it automatically anyway...

Help on Quality feedback

Hi Chuck and Larry and others,

I got some feedback from Al who is able to pick up KFTY-LD Channel 2 from Mt. St. Helena in the mountains near Yosemite. I think this is the furthest I know of anyone regularly watching an LPTV station (he is probably a few more miles away than Chuck, maybe 170 miles total). He says he picks up KFTY-LD 80% of the time, and only picks up KEMO 50 (RF 32) 30% of the time.

He said, only sub-channel 8 looked good on KFTY-LD. I'm running 2.4 Mbps on the .8 channel and the rest have been running 2.05 to 2.1 Mbps. So, I just now turned of the .9 channel on KFTY-LD and bumped up all of the rest of the channels so that everything is running 2.4 Mbps. Does everything look better to you? Granted, my .2 channel and .7 channels come from low quality feeds, but my .4 comes directly from a computer hooked into the mux / encoder, so it should look better as should the other sub-channels.

Perhaps I was too ambitious with 9 sub-channels. If so, then I'll stick with just 8 sub-channels going forward until I can afford a $130,000 encoder from Harmonic that can do 12 sub-channels. The Anywave encoder was about a tenth the price.

I did have problems with my Anywave encoder recentely where the static PSIP info disappeared. I restarted it, but now it looks like the .1 channel is saying .229. I'm asking Anywave for help.

Blessings,
Keith

Keith,

I just compared KFTY DayStar to KACA DayStar which is the only program they show. The color on KACA is over saturated. KFTY looks better in that regard. The video quality looks identical otherwise.

Maybe Al is expecting SD video to look like HD video.

I looked at the transmitter overlay in Google Earth for KFTY and there are a number of good spots on mountaintops west of Yosemite at around 170 miles. Al must be in just the right spot.

The most distant transmitter site that I can receive here is Mt. Toro at 132 miles. KMMD-LD 39 is the most reliable station from there with KION being second.
