Have you looked at the new LimeSDR as the core of such a device?

The APS RFI guys have the RADAR ENGINEERING ultrasonic receivers and
they are very marginally better than my homebrew.
They have a receiver now that is very effective - They can record the
waveform of the noise you hear - (they prefer to record from your
antenna ) then go in search of that matching waveform. If I was going
to spend any serious dollars on finding powerline arcing - I would do
someting that duplicates that ability .
I have tuned loops - and an ICOM R10 rx which is pretty effective but
nowhere near as good as the APS receiver . Have you looked at W0IVJ's
VDSL recording with a SDR -- that plus some way to record the waveform
would be great .
