This advice is free, so remember that you get what you pay for. Since Yaesu's advertising has already made the good points known, I'll concentrate on the warts and shortcomings. I assume that dual in band receive is done with the opposite band's receiver. This would explain the poor sensitivity, but it sure raises some questions about how the duplexer works. This swaps the left and right displays.
Manual control is the best solution.
There is no SCAN button on the front panel. Scan is initiated by holding the up or down button of the mike down for two seconds. The scan is blindingly fast when compared to the Alinco 590 that I used to have. Only one bank can be active for each receiver. I consider this an advantage, but you may not.
