As Tom said.
The cause of the signal gain when using a tuner is really a matter of
having a badly matched situation without the tuner.
In the old days (with manual tuners!), it was easy to demonstrate how a
mismatched load seen by the RX degrades signal.
Just start with random tuner settings.
You are right about the ATU. It was my mistake comparing the ATU-ON
which had been tuned at other than 50 ohm load compared to the
ATU-OFF.
As for PRE+ATT, I just measured MDS with the PRE and ATT settings
either both on or both off. Having both PRE and ATT switched on gives
