[App_rpt] Node 2047 up, running usb sound fob and a question on the node operation

Steve, and the group, I now have node 2047 up. This is a Radius M10 2m link radio. Question: Once I connect node 2047 to the Repeater node, 2059, I get the echo sound and some time lose control over voice and dtmf signals. Both nodes run off the same computer. 933Mhz 512mb of memory. Any thoughts will be appreciated. Oh and running both by the usb sound fob. Will / W4WWM
