I would start with installing Graphs1090:

> Let’s see if anything is there: ls /usr/share/graphs1090 Maybe lighty-enable-mod doesn’t work? Try this: sudo lighty-enable-mod graphs1090

Let it running for 24 hrs and see what the percentage of strong messages is.  
If it is higher then 5% reduce the gain.

Sometimes it can’t be lowered due to environment circumstances but that is totally dependant on your local environment.  
Max gain for the orange dongle is indeed 49,6.
