Audio returned on 145.1 I imagine we have BobChase to thank for that.

112.1 Down. Pops a "TITAN" on the screen, then just random pixels.

Just wanted to second the issue with channel 12.1 (112.1) it appears to be a (ateme?) titan logo (only displaying titan so not sure which part of such suite) mixed in with the stream which I have occasionally seen such as a watermark though usually much smaller and I have seen very old hevc decoders treat the video much like this, I believe last time was a video from germany when played on pre 7th gen intel graphics and played fine on anything more recent, but though very similar results, that probably isn't the issue but only mention in case they are trying a different encoding scheme versus something just bad in the process of putting the stream together.

I called them to let them know. Interestingly, 45.1 has SAP audio but the main is silent.

They are aware of the problem with 12.1 but it is a three station link-up to get it to air. I can't go into the details but the link-up is not working at this point.

103.1, 108.1, 133.1, 135.1, 139.1, seem to be off-line, didn't show-up after being rescanned.

Univision is having intermittent issues with its IP STL (Studio to Transmitter Link) and it may have been down when you did your scan. I just checked all of the streams on 35 and they were good. I then did a rescan in case there was an issue with the signaling on 35 and they are still there in the SD GUI for me.

Why is 135.1 the best looking channel of all?

It's a crapshoot on 35 as to who looks best at any moment - that's the wonders of using Statmux (Statistical Multiplexing). The another big factor is the quality of the source material. Univision and UniMas are both in-house feeds, so if the quality coming off the bird is there and if it makes it through the delay server, then you get to watch it in all its glory. Telemondo, PBS, and KTVK are all received OTA so they are constrained by the same factors as the others and then by 1.0 compression, decompression, and finally 3.0 (HEVC) re-compression. Not the best way to showcase the wonders of 3.0.
