clarkss12 296 Posted November 24, 2021 Share Posted November 24, 2021 Just noticed my favorite TV channel is missing from the Emby guide. Detroit 31.6. Link to comment Share on other sites More sharing options...
Carlo 4330 Posted November 25, 2021 Share Posted November 25, 2021 Hi, what tuner are you using? If it's an HDHomeRun try going to it's webpage and see if it's showing up there. You can also check to make sure it doesn't have an X next to it as well. If you have another app that can playback from this tuner, try that and then take a look at the stats showing for the channel in the web page. What does it show for status? If signal quality is marginal Emby might not have imported the channel. Link to comment Share on other sites More sharing options...
clarkss12 296 Posted November 25, 2021 Author Share Posted November 25, 2021 That missing channel is back now. No idea how it got back, or how it disappeared or when it disappeared. Strange!!! Link to comment Share on other sites More sharing options...

Carlo 4330 Posted November 25, 2021 Share Posted November 25, 2021 I bet it's a fringe channel that depending on signal quality can come or go. Link to comment Share on other sites More sharing options...

No, it is a major channel in my area........ I have no idea how that specific SUB channel disappeared. The other SUB channels were listed and played perfectly.

Carlo 4330 Posted November 25, 2021 Share Posted November 25, 2021 Do you have an amp inline? If not at those levels it shouldn't be dropping off due to signal quality! Keep an eye on your total number of channels (channel tab in Live TV) and if you see it change take a look at the logs or send them and we can take a look for you. Catching it in the log file is probably the only way we can figure out what is happening. Link to comment Share on other sites More sharing options...

That sub channel showed up using the HDHomerun app, and played. It only disappeared from the Emby guide. Link to comment Share on other sites More sharing options...
Carlo 4330 Posted November 25, 2021 Share Posted November 25, 2021 Don't know why but subchannels won't always be identical as electrical interference and other factors can cause issues for only certain frequencies and not others. You would normally never notice this unless the signal level is borderline to begin with. If you want to get a true reading remove the amp as right now any signal levels are mostly meaningless. Most common amps used have to high a noise dB rating which is often worse than not having the amp inline. A rating of 3 dB means 'double" so if your amp has a noise rating of 3 dB or higher it's likely causing issues. If it's one of the better amps in the 0.5-1 dB area the gain or the signal over the noise floor is still noticeable and beneficial. Link to comment Share on other sites More sharing options...

Carlo 4330 Posted November 25, 2021 Share Posted November 25, 2021 I was not saying this is something you have to do. I was just saying if you want to know the true signal quality you need to remove the amp. Just keep an eye on the channel count to see if this was just one of those strange things that happen every once in a great while or if it's an actual reoccurring problem that need more investigation. I have two channels in my lineup like this that may or may not be there but they are I think 62 and 64 miles away. Link to comment Share on other sites More sharing options...
