Re: Updated tuning file for Crystal Palace transmitter, UK

I'm surprised that it is providing you with AUTO values, if you look at most other entries for tuning files, everything is clearly marked and there are (virtually?) no AUTO parameters in use. The whole point being that we remove the guessing.

I'll update it next time I'm in the London area and have some time to generate the output.

Cheers,
Thomas

that more "precise" information might do more harm than good; more DVB
tuners seem to understand AUTO than QAM256, for example.

Any chance we can get more specific parameters for the T2 transmissions
than AUTO/AUTO/AUTO/AUTO/AUTO/AUTO?

It should be using UK Freeview Mode 6:
QAM256, 32K, FEC=2/3, guard= 1/128

Chris can you confirm that is what you are seeing?

I seem to recall that some time ago we tired to enforce using the
specific tuning parameters for all the options.

Cheers,
Thomas
