"WinAmp" tells me it's a streaming scanner feed. Level setting is a lost art as most feed providers can't be bothered.
In the past I used the Octiv "Volume Logic" plug-in, but it's no longer actively developed so you would have to stumble across it somewhere. These days I pump up the volume with VSThost running 2 plugins: TDR Nova equalizer to cut out the needless low and high frequencies, then LoudMax to smooth out the shouters and whisperers.
I made an overly complicated document describing all this that you are welcome to refer to if you want to set up all this stuff. It will pay dividends for any audio that passes through your computer.
