Hello again, I search on the mysql and found where are the transponder frequency table, is "channelscan_channel". My provider frecuencys are well known: 10729, 10817, 11435, 11626, 11317, 11508, 11685, 10979, 11038, 11097, 11156, 10788, 10876. Can someone help with a script to delete all frequency but not those? Kind regards. -- Josu Lazkano
