For quite a while now, I've noticed that 89.5 WSOU is much quieter on the air that almost any other station on the dial. And it's not that their audio is very lightly processed, like 88.3 WBGO; their audio is very tightly modulated and limited, but is peaking 2 to 3 dB lower than most other stations. So what's up? Do they have that "European MPX power limiter" on their audio processor turned on by mistake?
