[Bryan Taylor]

I think you just hit the nail on the head, this is the only radio taking audio through the mic connector, I will post my results after I try it out tonight

If you are feeding a radio that applies the pre-emphasis as part of the hardware, then don't add pre-emphasis in the configuration file.

The audio it sends out over the network is really nice. Just wondering if there are different settings for different style audio
