Mark, thank you for your patience and help so far. Please bare with me a little more.
Have tried multiple versions - didn't help. Got back to 4.2.5.
After that, I have got a better antenna, using w_scan tool found out that 8MHz bandwidth and 490MHz frequencies is what i need. So i manually added a MUX with these values. So far so good, it started finding services, but while searching for them it was writing weird entries to log file, like "unsubscribing" and "scan no data, failed". And when I have tried mapping them - all 58 found services have failed to map.
I am attaching log file, please see that
