Sound card line-in level

How do know you have the corrct input level for WSPR?
When using JT65A the waterfall gets bluer with increasing level and the there is a noise level indicator as well. There is nothing like this in WSPR.
I have found that JT65A needs a much greter level than MixW.
If I hadnt used JT65A I would have used my MixW setting which gives 5db less than the level I have to use with JT65A. I would be losing a lot of stations if I hadnt become aware of this difference.
So how do you set the correct level?
