Hi David!

First of all, thanks for your suggestions.

I'm not saying that the network can't be a problem, however, there is seldom anyone coming into the node via Echolink or ASL.  The audio dropouts are predominantly from repeater receiver audio, during local QSOs.  When I spoke of the CAT7 cable with the ferrite chokes, I was referencing the interface cable I constructed to run between the RIM Lite and the repeater itself.  The RPi3 is connected to the network via Wifi to a router that is no more than 4-5 feet away.  I've seen no evidence of the link bouncing at all.  We did not connect it via Ethernet because all the host's router's ethernet ports were full.  We have purchased a switch to expand his network so that we can connect via Ethernet instead as soon as we get approval from him to do so.

I am wondering if this might be a USB problem, however I have found no indication in any of the system or Asterisk log files of that.  The RIM Lite is the only USB device plugged into the RPi3.  I suppose it's also possible that the RIM Lite is wonky, but I have no other device with which to replace it.  I have not yet put a ferrite choke on the USB cable, but plan to do that during my next trip to the site.

I really appreciate all the ideas that are coming forward.  If I don't get this solved soon, I'm going to have to put the original CAT200 controller back in place, hang my head in shame and restart this whole project at a later time. (Oh well, it won't be the first time for that! LOL)
