I can agree with Jim on this.
Proper use of compression {emphasis on "proper} does raise the average
audio level. Excessive compression can cause a "pumping" sound.
Compression with incorrect attack and release times, largely defined by the
program content, can also make things better or worse. Compressors with
automatic variable ratio attack and release times plus variable input to
output ratios do a really nice job to hold the audio level up and do not
artificially color the sound. The Teltronics LA-2A is a good example. Also
the CBS Labs VolumeMax is another good one.

Why? Compression VERY effectively increases talk power IF done well. 10
dB of compression on peaks should be considered a practical limit with a
rig that does it well. And 10 dB is like multiplying TX power by 10.
Virtually ALL commercial broadcast audio is compressed, much of it by even
more than that.
