Let's have more granularity with the audio level controls in the TX window.

Maybe a right or left click to magnify and sticky bars that will hold a peak for "xxxx" number of ms. More level number indices on the graphs would be nice too! Also the compression graph IMHO, should read 0+10? db instead of -40 to 0. Same with the downward expansion, say -60-0. Different colors for each. The downward expansion bars run from right to left, while the tx audio level bars run left to right. I don't see a need for a top end +20dbm if the max is 0 dbm for the ADC. Please opine!

Downward expansion should be in db. It appears to me that PSDR uses percent but I am far from certain.

I would think everything is referenced to the ADC input of 0dbfs
