Yes, it was the Ultraprobe 2000 made by UE Systems. I finally found a
vendor with a price quote on the Web. The hand held unit cost around
$4,500, and the parabolic clear acrylic dish by itself cost $1,750.
I told someone that for that kind of money I could afford to list my house
and move to the country!
Over the weekend I ran my transceiver off a car battery and flipped the
house main breaker to kill all the ac coming in. The noise (I now have
identified a corona hash sometimes at 10 db over in addition to the pulse)
kept right on rolling in. Now I can confidently go hunting and tell them
it's not my problem.
I think the ultrasonic receiver Ed mentioned is at that web site he gave but
under "acoustics - listening devices" and not "ultrasonics."
Under ultrasonics all I found were gadgets that make noise instead of
receiving it. See: http://www.amazing1.com/accoustics.htm
Let's hope it works, but that HT someone mentioned that goes to 330 Mhz AM
is a good deal too!

Yes, please post your findings on K2QAI's testing the unit as
well. If it makes the grade in the ARRL labs then I'd consider
budgeting one for our ham club as a loaner.
