UDRC - setting audio levels

Richard Bates <richard@...>

Help please setting the audio levels on the UDRC.

In the notes on setting up the card with the Direwolf Packet Modem, there's a script given at
which sets up some defaults levels.

My question - how do I get a larger Tx output level?

The script mentions a high-power DAC and gain settings?
What does it take to get a 2v pk-pk audio output?

Thanks for any advice on this.
