I have one of these units ... http://pw1.netcom.com/~t-rex/ ... A nifty
device. I purchased the complete
unit as a kit about 7 years ago for around $40 plus shipping. I have never
seen him advertise
the kit, I found out about that after I contacted him. The gentleman that
produces
this kit is also a ham, a KC7 .... in Nevada. I added a $14 radio shack
speaker/amplifier for
all to hear. I have not used it to find noise, when the rain stops I'll see
how it does. I does have
about a 150' to 200' detection range on the local bats depending as per my
gain setting.

Hi Chet:
Just add a "l" to the end

I own one of these units - it is great for finding power pole problems.

Phil, W0XI, has put a kit ultrasonic detector on the market. Well worth
looking into.

I have used one which the ARRL RF lab brought down here to address a very
serious problem. We were able to identify the BOLT on the insulators where
arcing was coming from, photograph it, attach both the audio file and the
spectral display unique to each offender and the power company still
reneged. Until FCC saw this and that was the end of the power company
resistance. Problem fixed. Those devices are not easy to aim however. You
need a steady hand and lots of patience.
