Hi Jay, I had a similar problem recently. on a repeater that worked perfectly using an older motherboard... ... To check if its the same problem, is the URI green LED flashing at its normal rate, e.g. 3-4 times a second or is it a lot slower? And are you using the current ACID install????

Thank you to the guys that sent me wiring info, but i'm still not working right. The audio being transmitted from the repeater sounds like it has AC buzz in it. When I transmit with my portable, the repeater only stays keyed for 5 seconds. Does anybody actually have this working? What should my node stanza in usbradio.conf look like?
