[RFI] FCC Complaint Filing

[Cortland Richmond]

For some years now, I've had good results chasing down interference with 
an Icom R-7000/7100,etc' , handheld wideband scanners, and even a 
Kenwood HT with wideband coverage. A remarkably simple – considering the 
effort and primitive construction – loop antenna made of  coax (semi 
rigid or even RG-58) with the end of the center conductor  terminated on 
the shield near the BNC, simply plugged into the scanner's or HT's input 
connection, let me track down the infamous 3.52 MHz AT&T "wireless" 
signals;  and that configuration even let me find some 2m powerline 
interference N0rth of Petaluma.  Its location, next to the local 
airports control tower, got *immediate* attention.

I even got a laugh out of tracking down the AT&T stuff. I'll begin by 
explaining that I junked my television set in 1997.

I had an EMCO-6511 loop antenna mag-mounted on the car roof and would 
drive around until I heard more 80m noise, and then I would go from 
house to house with my AR-8000 and the little loop, sometimes 
pinpointing the room where the "powerline modem" was plugged in.

The laugh? I noticed, as I drove around, people running out of front 
doors into  back yards, which – if steak on a barbecue needed looking at 
– might have been the reason. However, I realized it was people who 
thought it was from AT&T, tracking down unauthorized cable sharing 
during the Super Bowl.
