Who: JH3VFI Masanori Yamane, JL1GJE Kensuke Sawada, JA1NVF Katsumi Yoshinuma, JA1BNW Takayuki Hiroshima, JI3OPT Michiharu Nakamura, AD6ZY Paul Gill What: find the source of THE NOISE
Where: Yokosuka Research Park, Yokosuka, Japan When: 2004-03-06
Why: we're just like the Grinch, WE HATE NOISE!
How: hooked spectrum analyzer to rig end of coax line to measure the noise coming in from the antenna and coax run. Made chart of antenna orientation versus noise level.
Northwest is low noise (which means antenna and coax run from the antenna down through the building to the rig is not the cause of the noise),
Southeast is high noise. Use portable radios to find the noise "hot spots" up on the roof, most likely suspect is a water pump.
