[Doug Crompton]

LaRoy,

 I didn't read through this but if it works for IRLP it will work for Allstar. Maybe see what this guy did if anything...

> I have a GR1225 repeater that I acquired.  It was a functioning 
> standalone repeater.
> I now have it connected to a Pi and working.
> 
> The audio from the radio sounds great but the issue is with the amount 
> of volume I am getting from the reciever.
> I still peak over 5kc in simpleusb-tune-menu on loud voice peaks, and 
> that is with a Bofeng ht.
> 
> I have rxboost set to 0 in simpleusb.conf.  I am down to 10 on the 
> receiver adjustment of simpleusb-tune-menu.
> All this and the audio is still a little hot.
> 
> This is the first gr1225 I have played with.  I am not sure about the 
> settings in the radio.
> The Rx Audio Output is set to flat.
> Operation Mode is set to Repeater w/Ext Controller.
> Repeater Audio Mode is set to EIA.
> 
> There is a setting on the service menu, some type of gain setting (don't 
> remember exactly what it was called) that went from 0-31. This was set to 4.
> 
> Is there any other setting I am missing that would turn down the volume?
> Is there any pot adjustment in the radio?
> 
> Do I need to add a resistor or pot in the audio line to adjust the level?
