The log file shows that frequency 43400 could not lock. We set the frequency, modulation type, and symbol rate, but could not get the tuner to lock. Its lock status is 0, and signal quality is 0 too.
During the scanning of the other frequency, we actually did scan NIT, which gave a number of transponders, including the one for frequency 43400. But we just could not tune to it.
Is this channel protected?
