1600000 kHz == 1600 MHz == 1.6 GHz
uh, operator have configured wrongly neighbour transponders ?


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?
