'ACID Centos6 on a 1.8G, 4G ram, 120G ssd, 64 bit computer test results.' hile injecting a 1khz tone at 3khz into node #1 receiver, the waveform on node #2 transmitter has a ripple. Configured as a simplex node with a URI, connected to a second node, receivable with a service monitor, w Reverse this test and the waveform on node #1 transmitter is clean. Using the exact hardware, conducting the same test with ACID centos5, and Xipar centos6, the waveform is remains clean. I am not experienced at this, but I took a long shot and recompiled the software with different channel drivers. The results were the same. I haven't seen much chatter about ACID Centos6, so I thought commenting on the findings may spark some interest. Comments or Criticisms accepted gracefullyJK
