Steve Zingman:  I believe the dropouts are primarily on receiver input.  I've not noticed them on Echolink inbound traffic.  The CPU load is minimal.  Generally under 2% used.  We are using USB_RADIO without DSP (I couldn't make that work initially for some reason.)

Steve Agee:  As I said, the CPU load is minimal.  There might be tiny momentary peaks, but there is no sustained load on the processor.

Neil K8it:  The wireless connectivity doesn't "seem" to be a problem.  The router to which it is connected is only about 4 ft. away.

Thank you all for the suggestions.  Would love to hear any other ideas you have!
