Batboard

I have a repeater running with a GM340 and a CDM750, and have bought a original HLN3333B RICK.
The repeater was running with a other interface cable and the audio was good, but now with the RICK is lower than before.

About a year ago i read a topic on this board about a resistor next to de R23 trim, that can be removed and then solder a bridge instead.
But i do not remember witch one it was and can't find that topic again, can someone help me? I want to use the original RICK but with higher audio if possible.

I have used the search function on the board but found noting about it.

I have received a mail with the wright resistor name, and today i removed it and placed a bridge/jumper instead of it.
Now the audio is fine and as it supposed to be, so thanks for the support. This item can be locked or removed.

Btw. The resistor that has to be removed is de R25, just under the R23 trimpot.(or lower the value from 1,5k to 0k)
