I have still no knowledge why scanning didn't find any other freqs. If there is error in driver then most likely it is TDA18218HN tuner driver issue since thats reverse-engineered one and without modulator I cannot ran very much tests. Could you say which are missing freqs and bandwidth of those freqs? Antti -- http://palosaari.fi/
