Terrestrial Tuner HD problem

[db49er]

I very rarely use my terrestrial tuner and the last time was several months ago when everything worked fine. Now I have problems with HD channels, ABM and EPG.

HD disappeared and the only way I could get them back was to do a full UK rescan as opposed to my region. Have since done a full frequency scan which resulted in a message telling me to disable my current provider and run a new ABM scan. Did that and ABM all looks good but no EPG and HD signal only 40% against 100% on SD.

I seem to remember some reference to T2 in one of the recent update packages so thought I would pose the question before going down the hardware route.

There is a thread in the ABM section about Frequency finder. Please use it and upload the file it creates for you.

Sorry, I missed the above statement. Just for reference purposes, that applet has found the following frequencies

frequency="562000000" transport_stream_id="3006"
frequency="578000000" transport_stream_id="5040"
frequency="586000000" transport_stream_id="6040"
frequency="618000000" transport_stream_id="1049"
frequency="642000000" transport_stream_id="2012"
frequency="666000000" transport_stream_id="4089"


Which mast does your aerial point to?

Pontop Pike, but scan did not show any HD channels until I changed to "All UK"

Just noticed that it still does not show BBC News HD. Maybe they have changed something at the transmitter?

@db49er, can you upload the latest xml file created by frequency finder please?

Just noticed that it still does not show BBC News HD. Maybe they have changed something at the transmitter?Such as no longer broadcasting a signal in the 700MHz band, which is where the COM7 (BBC News HD) signal used to be.

EDIT: Based on old data. Finally tracked down the current data,

The 39->55 numbers are channel numbers.

39->618MHz
42->642
45->666
32->562
34->578
35->586
55->746

It's the last one which is odd. It was supposed to be shut down in Nov 2020. But then so was the same channel (for the same mux) on my transmitter, and it's still running. lamedb5 has:

t:eeee0000:a000:233a,t:746000000:0:5:5:3:2:4:4:2:0 :1:0



So you should (I expect) still be getting it.

COM7 on frequency channel 55 is usually the most difficult mux to receive due to the high frequency combined with the fact that it's a countrywide SFN.

I do apologise, only just seen this.

The only HD channel i have now is BBC News!!!!
