Also Check for Ground Loops between chassis connections. And look for DC riding on the audio leads as well. And like Jim said use a 1:1 transformer on the audio leads if you cannot isolate it. -- Thanks in Advance Bob Brown, WØNQX Kansas City Metro Area http://sm0kenet.net http://byrg.net http://kcdstar.byrg.net http://w0nqx.blogspot.com Quis custodiet ipsos custodes?

Hey guys,
I am running an 800mhz VIA ITX Board and a quad pci card. The board is 2004 vintage. I have a distinct noise on TX audio both through my node and remote base. I have shielded cables to both remotes, I have replace the power supply and greatly reduced the high pitch noise.
An interesting note: the tx audio port is quiet when first booting the node pc. Once asterisk is running the noise returns.
Has anyone seen this before? Do I have a bad main board or did I miss something else..
Thanks for your help!
