Going further on the scanning for DVB-T ... / 2008-12-24

Going further on the scanning for DVB-T channels I found w_scan, an automatic full-band scanner for DVB-T and DVB-C. The page is in German, but the application itself speaks enough English. This program finds all active DVB-T transmitters and fetches their network information table. On a test run in Utrecht I get:

# T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy
T 498000000 8MHz AUTO AUTO AUTO AUTO AUTO AUTO
T 522000000 8MHz 2/3 1/2 QPSK 8k 1/4 NONE
T 618000000 8MHz AUTO AUTO AUTO AUTO AUTO AUTO
T 706000000 8MHz AUTO AUTO AUTO AUTO AUTO AUTO
T 762000000 8MHz AUTO AUTO AUTO AUTO AUTO AUTO
T 818000000 8MHz AUTO AUTO AUTO AUTO AUTO AUTO

During frequency scanning it even finds a transmitter at 618 MHz (UHF channel 39) but it can't find any valid data there. At 522 MHz (UHF channel 27) is the DVB-H service marketed as 'Mobile TV' in the Netherlands.
