[RFI] Ultrasonic Dish

[Patrick Dyer]

In Feb 1996 I located an RFI source some 3000' n.w. of me using various 
receivers and ultimately a Radio Shack Jetstream Mini retuned to 144 MHz 
with 4-el from an 11-el Cushcraft 2-m beam.  It was a busted out street 
light (not a "safe" area to wander about in at night).  It was 
reassuring to hear the intermittent RFI match the acoustic noises coming 
from up there that I could detect with my ears alone.  I documented that 
with my 8mm camcorder (maybe I should put it my YouTube collection).
