[RFI] A fun and educational RFI toy.

: Be careful with LISNs and preamps.  Turning on and off the DUT (device
: under test) will create significant transients to the receiver.  I have
: never hurt a receiver or spectrum analyzer but have killed a couple of
: preamps.

I have not experienced this with my unit (hopefully won't).  The output is 
very low, I can
only make an educated guess at the moment without equipment set up to test 
it, but based on the sensitivity of my receiver and the "S" meter reading 
equating to
about -120 dB and looking at a conversion chart for 50 Ohms I would say 
around 225nV.

I have an idea for simple device similar to a LISN box that most anyone can
build, trying to figure out how to sample the AC lines safely, thinking a
torroid and only a turn or two of wire on the receiver side to keep voltages
low and provide adequate signal strength, I'll play around.
