I am running an RB-RIM-Maxtrac with HamVoip software. When looking at the View status in Simple USB Tune menu, I notice the COS input is staying keyed. Everything seems to work OK. Is this normal or do I have something set wrong that would cause this? I have attached a screenshot of the menu. 73 Tim Webb - KK4WH606.909.2094www.facebook.com/kentucky220
