[RFI] Raucous ruckus...

[KD7JYK DM09]

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.
