Yesterday I picked up a Klein Tools Digital Circuit Breaker Finder, model ET
300. In itself is is a poorly functional erratic POS at best and I will be
returning it shortly. Nothing beats flipping breakers to figure out what
they go to.
The "transmitter" plugs into and is powered by a wall receptacle. It claims
to be traceable up to 1,000'. I do not know how it operates, but it creates
a heavy buzzing signal every 60 Hz across a wide amount of spectrum. On the
equipment I used, it generated noise from 30 KHz to 30 MHz, strong to about
5 MHz, then tapered up to 30 MHz.
When I went out to test the receiver portion of the tracer, I took my LF
noise finder with me. I tured it on in the house, it was hammered by
insanely strong noise- everywhere, unplugged the transmitter, noise gone.
Went outside, no drop in signal strength within a hundred feet or so of the
house.
I made an audio recording of the signal from the tracer as heard on my HF
receiver in AM as well as a spectrogram using Argo.
Available upon request, if someone would like to put the info on their
website, that is fine too.
