Need help

[Shawn Smith]

why can't i get ABC and I been trying all morning

[nmongrain]

Shawn, the landing page clearly states, "ABC remains unstable or unavailable."

This means the local broadcast signal is too weak. In my market,  some of the local broadcast channels have been reducing signal strength to "encourage" viewers to subscribe to streaming services or cable, where they receive higher advertising revenue. 

If you live in the Bay Area,  complain to that station.

Can you at least put a notice for everyone on the Puffer homepage about ABC's status? Is it ever coming back?

[Francis Y. Yan]

Just put up a notice. We are still testing KQEH but given ABC has been unstable for more than a year, having any other channel will probably be better!

Best,

Francis

How to solve the KGO reception problem:

Step #1: Use the ATSC 3.0 KGO feed being broadcast on KRON's ATSC 3.0 lighthouse. https://en.wikipedia.org/wiki/KRON-TV#ATSC_3.0 The feed is not encrypted, and reception with ATSC 3.0 is way better. This should fix the problem.

Would you be able to do that?

"Puffer uses a Blonder Tongue 8-channel 8VSB-to-UDP demodulator and a lot of software we wrote (back in 2017 when this project began) to process the MPEG-2 TS from an ATSC A/53 signal and keep the audio/video in sync through dropouts (which sometimes affect the different streams differently). It would be a lot of work to implement all this for ATSC 3.0, not counting the new demodulator, and it's probably not that valuable from the point of view of getting better data from the studies we run on the different bitrate-selection or congestion-control schemes. If you know somebody interested in funding this work, happy to talk, but otherwise I doubt we can justify the software engineering (or procurement) for it."

In other words it would take some money, and a lot of time to accomplish.

I'm in Houston Texas and just Don't understand what's the issue when I'm assuming it's y'all connection

Okay. I looked into the signal strength of KGO. I put the coordinates of the computer science building into RabbitEars assuming that is where the antenna is.

https://www.rabbitears.info/searchmap.php?request=result&study_id=2682129

The report indicates the signal strength of KGO should be good, so what is going on?

I don't have the measurement of the height of the antenna above the ground, I could get a more accurate report if I had that.

I did take a look at the terrain path profile. The green line represents the terrain and the red dotted line shows the line of sight path. On the profile, the line of sight path looks like it gets very close to the terrain. Maybe the issue has to do with the antenna height? This is just a guess though.

Wait a minute! Are you trying to get the KGO signal on VHF channel 12, or the KGO signal on UHF channel 35? If you are trying to use the VHF one, that would explain your problems and I would switch to the UHF one.

Hi Shawn, 

The issue is with the signal strength. You know, the same reason you don't get KTRK in your home.
