Adelaide Foothills DVB-T tuning

Adelaide Foothills DVB-T tuning

[Ian W Roberts]

Dear Linux Media people,

I've struggled to tune various DVB-T devices in Mitcham South Australia. 
Mitcham is in the foothills area of Adelaide without a clear line of 
sight to the main Mt Lofty transmission towers. The tuning wizards, for 
instance in me-tv, only display a single location file for Adelaide 
(au-Adelaide). There is an alternative transmitter in the Adelaide CBD 
(Grenfell Street) to cover this area.

I did quite a bit of web searching looking for information about tuning 
in this area without much success and no clear statement how to get 
DVB-T devices tuned here.

Guessing that my problem was due to the lack of tuning information for 
the Grenfell Street transmitter I created a new file 
/usr/share/dvb/dvb-t/au-AdelaideFoothills with the following data. I 
have been able to tune the 18 stations currently broadcast using the 
standard me-tv tuning wizard. :-) I'm not sure that all the data in that 
file is optimal but it works! Does anybody have any improvements to suggest.

------------------------------------------------------------------------
# Australia / Adelaide / Grenfell Street
# T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy
# ABC
T 781625000 7MHz 3/4 NONE QAM64 8k 1/16 NONE
# Seven
T 711500000 7MHz 3/4 NONE QAM64 8k 1/16 NONE
# Nine

# Ten
T 732500000 7MHz 3/4 NONE QAM64 8k 1/16 NONE
# SBS
T 760500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
------------------------------------------------------------------------

It would be good if an entry equivalent to my au-AdelaideFoothills could 
be included in the linux-tv packages so that residents in the Adelaide 
foothills would have an easier experience with DVB-T. How can that data 
be included? Who is in a position to incorporate the additional location 
entry.

bye
