It would be cool to have a few db of AGC. On Mon, Mar 7, 2016 at 8:19 PM, John Griffith <john@qso.com> wrote:
Haven’t found much on this, but I remember a while back I read something about one of the codecs for Asterisk that had an internal option to enable ALC (automatic level control). Not sure if this was a compression codec or not, but it would be nice to use a compressionless one (like ULAW) for use in my repeater output. Right now I’m using an analog ALC unit between the URI and radio, but it’s introducing AC hum into the repeater output. The noise is originating in the poorly shielded ALC unit.
Does anyone have ALC working within Asterisk? If so is it hard to make it work in App_Rpt for the
repeater output? I need to keep the input constant because I’m using DSP and CTCSS for squelch, so output is all I’m looking for.
Thank you.
