QUESTIONS

Does the Channels API need to be updated to retrieve ATSC 3.0 channels?
Is there a way to force a HDHR to tune to a channel so I can get the RF channel number and signal strength information to help diagnose why some channels will not tune? Either with the HDHR or channels API? Or is there a macOS/iOS app that will allow me to troubleshoot?

tmm1 · March 8, 2022, 8:01pm

Did you favorite the channels in the app?

elvisimprsntr · March 8, 2022, 8:06pm

I stared them on the HDHR device directly.

Do I need to do it in the Channels app too?

tmm1 · March 8, 2022, 8:06pm

Yes each app has its own favorites

elvisimprsntr · March 8, 2022, 8:08pm

Thanks.

I added my ATSC 3.0 channels to favs in Channels app. Works!

Some of my ATSC 3.0 channels are too weak to tune.

Any advice how to diagnose?

tmm1 · March 8, 2022, 8:16pm

update to latest hdhr firmware

check hdhr log on web ui

elvisimprsntr · March 8, 2022, 8:27pm

This is what I get in the log for the 5 channels that are currently broadcasting.

2 of 5 are no video data

I would check the HDHR forums for the ATSC3 details in your particular market. You can contact them there or via [email protected] as we don't have visibility or expertise in the hardware tuning aspects.

elvisimprsntr · March 8, 2022, 9:15pm

Thanks.

I removed the SD LTE filter from my antenna, which seems to help a bit

Fofer · March 8, 2022, 10:38pm

Interesting. I have the Channel Master version of the same LTE filter installed. It helped me with the signal stability of two local channels in particular, in Los Angeles. I'm using an indoor antenna though.

elvisimprsntr · March 8, 2022, 11:11pm

I currently have an un-amplified attic antenna with a ~50-75' run to a junction box, where I have a 1x8 active amplifier to distribute the OTA signal throughout the house. It doesn't help that I have a concrete tile roof. I've never had a problem with ATSC 1.0 signals, even during tropical storms or hurricanes. I might be able to relocate the antenna to a dormer window and/or add an inline amplifier at the antenna end. I'm guessing the insertion loss of the filter was just enough to weaken the signal.
