Open DRM-Free Unencrypted DVB-T2 Tv and Radio in Austria

Most things in Austria terestical TV got encrypted since DVB-T got shut down, but there are still three TV channels and three Radio Channels unencrypted. I had some hard time to find out how to get it working using linux... and non existing documentation of the sender did not help. Howerver... if you have use for detailed channel setup arround vienna, take a look: Tvheadend seems to lack channel search support using DVB-T2, but puzzeling every value together works fine: Mux A-WNB Channel Frequency: 498000000 Bandwitdh: 8MHz Constellation; QAM/16 Mux B2 Channel Frequency: 578000000 Bandwitdh: 8MHz Constellation; QAM/16 Unstable Twin Tuner I am using some twin tuner. That was not supported on older kernel version, but is now supported on current versions. Great? nope. The system/tvheadend gets unstable if two tuner are enabled running for weeks. After disabling one tuner, tvheadend runs reliable for months. List of unencrypted streams Example stream info tv channel   Surround sound Too

if you get a cad plan in pdf format you have a problem: Pdf can not be loaded in most cad programs. I used pstoedit to solve this problem. Pstoedit is a free tool to convert pdfs to dxf. What you have to do: Install pstoedit Install ghostscript shot at your pdfs: pstoedit.exe <pdfSource> <dxfOutput> -f dxf thanks to the author of pstoedit! Here is the pstoedit.exe -help output: No output format specified (-f option) and format could not be uniquely deduced from suffix .dxf of output file Available formats :     psf:            .fps:    Flattened PostScript (no curves)     (built-in) -------------------------------------------     ps:            .spsc:    Simplified PostScript with curves     (built-in) -------------------------------------------     debug:
