Transmitted audio enhancement techniques continue to grow in popularity.  More and more operators are adding audio processing hardware including equalizers, compressors, limiters and special effects units to experiment in  improving their overall sound while enhancing their modulation.

The primary station's audio system consists of a Heil Goldline Pro microphone to a Behringer MX602 mixer.  A reverb, graphic equalizer, compressor and leveler are also used to enhance audio performance.  Additionally, a second mixer and Sony Minidisk are used to record and playback incoming signals.  A computer is available for digital modes and logging, as well as audio analysis.
