I've read on some page from linuxtv wiki that most of transponders files needed to be added a 167k offset to work. Honnestly, it works fine with or without this offset for me. > +T 570167000 8MHz 2/3 NONE QAM16 8k 1/32 NONE > > This frequency looks very suspicious, as it is (without > the offset) in use with different parameters by a Single- > Frequency Network along the Hoch- and Oberrhein, including > a non-directional 50kW tower at the Totenkopf, Vogtsburg/ > Kaiserstuhl, and somewhat closer at Baden Baden Fremserberg, > which should blast well into much of the Alsace.

I do receive both French and German channels. So obviously, some come from Nordheim antenna while others are likely to come from Germany but I don't know how to differenciate these. I have some table frequency list here: http://www.tvnt.net/V2/pages/342/medias/pro-bo-doc-tk-frequences_tnt.pdf See the "Canal" array, page 20 for "Strasbourg". I don't know how to determine transponders frequencies from this list. Ben
