MYSTERIOUS INTERFERENCE IN THE SAN DIEGO AM BAND


On Wednesday night, January 11, 2006, unidentified
wideband interference blanketed the AM broadcast band in San
Diego "with peaks all over the dial" according to one report.
The interference was heard from 150 kHz to over 5 MHz and
obliterated weak out-of-town AM broadcast signals. KNX was
said to be 90% covered by static and noise. These observations
were made along Highway 52.


A second report (this from an experienced broadcast engineer)
noted RFI "from 540 kHz through 5 MHz [that] came on after 6 PM,
1/11, Wed evening. In the morning the hash was gone and [the]
band was back to normal Thursday night.... The RFI could NOT be
nulled out and was as strong OUTSIDE as inside a house. This is
using battery portables with circuit breakers on the house pulled.
Also noticed on several radios and driving in [a] car. Pretty
widespread. So strong a slight hash was heard under KOGO."

I'd bet one of the local Teslamaniacs has fired up one of their toys.
A Tesla coil with a spark gap, or a home made arc furnace.

Sound like the crap my neighbor's lights put out, though. (A low voltage
halogen system on a dimmer, I think). The hash is S9 on 41 meters.
BPL doesn't stand a chance.
