Ralph and Jordan, I think that you both are talking two different problems that I will need to work individually with to figure out the issues.
Ralph maybe a buffer or VAC audio setting and Jordan maybe a resource or antenna switching issue, may take several exchanges to figure what is happening with both.. So let's take these off the reflector and handle directly, no need to take up the reflector bandwidth..
