Hi everyone:
Has anyone had any experience using an ultrasonic receiver of some sort to
find an arc?
American Science and Surplus sells an ultrasonic receiver kit for 18 or 19
bucks. I have not tried it but the blurb about it mentions hearing
electricity arcing among other things. I've read that one method the pros
have for finding the exact arc qth is through the use of ultrasonic
receivers (except theirs are positioned at the focal points of clear plastic
dishes they can aim). Anyway for the money it might be worth a try. See:

I was thinking maybe I could get the kit and kludge something together with
a big plastic dish, like a giant salad bowl? do they have to be parabolic
or just something that gathers the sound? Okay, it's a little crazy but I'm
not called a ham for nothing, hi.
Anyone know of a source(s) for something better? How much do these things
cost? Thanks,
73,
Rob Atkinson
