Hi guys... I've got a SimpleUSB full duplex system connected to a port on my controller (Arcom RC210) and I've noticed something weird with telemetry announcements, specifically connect/disconnect messages, and I've tried with both a URI and URI-X with the same results. I suspect the audio may be clipping in the controller, even though the levels appear to be adjusted correctly for 3Khz deviation @ 1Khz modulation in and out, so I want to make sure the URI(s) are not the problem. I see you can build a loopback connector ( docs.allstarlink.org/drupal/node/143), but what's the best way to test this? Is there a way to inject/monitor audio? I'd like to see if I can reproduce the choppy audio so I can eliminate this being something in my system and/or URI(s). tnx Stephen K1LNX
