On our local EDACS PST clear voice audio from the switch receives ALC and
minor compression before going to the dispatch consoles or being repeated.
This helps maintain reasonably constant loudness to the dispatcher's
headsets, and makes for more uniform system
The ALC cards process both repeated audio and console audio unless the
system is in bypass. I can scan the block and level diagrams if you
like. PST is Public Safety Trunk - Ssb
I'm assuming when you say clear voice, you mean analog, (VOICE APPLIED

In other words, simply adjusting the output of the controller to

Mathew,
This is a common problem, especially when users with multiband/multimode
radios use them on FM repeaters, not realizing that they are
overdeviating. I guess it's a mixed blessing that some kind and gentle
listeners will advise a repeater user that his/her signal is loud and
clear when
