Actually it's not the repeater that is causing the interference, but rather
a user of the system, and was measured with my CE-6030 monitor. Was hoping
to avoid a war, as he is an older gentleman whom can be stubborn, and I
would rather solve than fight. I'm getting ready to try the 10db pad and
see if that helps any.
