KB7WOX calls what he has been doing since 2012 (!) "selective pattern analysis".

A better description would be obsessive-compulsive behaviour, fixated behaviour or ritualistic behaviour. The detailed and repetitive monitoring of disruptive transmissions has replaced the original goal of actually finding and eliminating those transmissions.

“We all have our routines," he said softly."But they must have a purpose and provide an outcome that we can see and take some comfort from, or else they have no use at all. Without that, they are like the endless pacings of a caged animal. If they are not madness itself, then they are a prelude to it.”
― John Connolly, The Book of Lost Things

At one time I had the slightest hope that the op would actually go track down the problem. Now I realize that they seem to be happier posting inane information. No longer following, just putting him on 'ignore'

Device is simple. It is an older second TV output channel of a dual receiver converter as used by satellite and cable TV. The other is a digital to analog TV converter for the old analog TVs, some people still use them with the converters. If the converter is left on and the TV is switched off the thing could run for days without it being noticed.
