BTW, analogic shut down has happened (18 may, 00:00) for the entire french region "Pays de Loire", so a lot of transmitters are affected. "fr-Laval" now uses these freqs: 714000000 570000000 770000000 762000000 650000000 786000000 -- Christophe Thommeret -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
