The corresponding code in the demod driver which caused the last logs of
the MB86A16's activity ..
1416 dprintk(verbose, MB86A16_INFO, 1, "SWEEP Frequency = %d", swp_freq);
1417 swp_freq += delta_freq;
1418 dprintk(verbose, MB86A16_INFO, 1, "Adjusting .., DELTA Freq = %d,
SWEEP Freq=%d", delta_freq, swp_freq);
1419 if (ABS(state->frequency * 1000 - swp_freq) > 3800) {
1420 dprintk(verbose, MB86A16_INFO, 1, "NO -- SIGNAL !");
1421 } else {
Something is wrong. There is no signal at all ?
