[App_rpt-users] URI loopback testing

[Stephen - K1LNX]

Thanks Jon :) I think what was happening was that my audio was clipping in
the controller and causing the dropouts. I am in a "transitional" period at
the moment as I have a new replacement controller coming (SCOM 7330, it's
replacing an Arcom RC210) so I will be a few weeks before I can re-visit it
all.
