Here is another suggestion. If changing the monitor's contrast control while it's running affects the interference, then it is coming from the monitor. If not, then it is coming from the card, OR the
This has been going on in Germany for months. YEars, actually. It is big news there. I alerted the ARRL to the "Nein zu PLC" efforts German hams and SW broadcasters are taking and found a few Web pag
Bob, I drove a Taurus for a few years, and had fuel pump noise too. But the blankers on my rigs DID cut it out. Are you sure it's getting in via the antenna? Sounds as if it might be in your audio st
Buy a cordless telephone that operates on the channel their baby monitor uses. Use it a few times so they are sure to hear you. When they mention they are hearing your telephone, tell them they can p
This sounds very much as if the residence involved either had bought a "wireless" (carrier current) extension modem operating on 3515 or had one installed by the Cabe TV folks to connect the cable-bo
You need a small UHF beam and AM mode receiver. Operating at (say) 440 Mhz, you can use a beam to idetify actual sources. I used aircraft band AM to get close to a source, and zeroed in on it with 1.

Pete, Just a hunch, but look for something electrical close to the feedlines or array control lines, or array control logic power source. If you have to get close to the antennas to hear it with your
The FCC requires receivers operating between 30 and 960 MHz to comply with FCC Part 15. That's why the sticker is on it. We would be well advised to ask the FCC to make these labels made more specifi
Your 67 KHz spacing sounds like a high-resolution monitor or a switching power supply. Cortland As for the below, well, these gadgets didn't go away just because we got a promise from one manufacture
Kris, I was very impressed with Mike Tope's Reply Comments. It looks like Mike knows how to do 'em! I hope that the rest of us aren't ruled out for not copying the folks we were replying to. Cortland
Jumping in... BPL seems to be presently treated as a carrier current system for sections 15.107 (NO conducted current limit above 1.705 MHz) and 15.109 (radiated limits). BPL claims (hah) to be an un
Interesting post. However, this appears to be little threat. Power and signal coupling by induction falls off very rapidly with distance. Note that even with a "booster antenna" (probably a larger ar
I think the RF will be low-power, generated at the sensor board, and probably (to save power) only when a card or item is in place to be scanned. I do not see them adding wiring to send several watts
144 MHz plus or minus is pretty common, as a lot of devices -- even pretty rudimentary stuff, nowadays -- uses 4, 8 or 16 MHz clocks, and current technology is built around fast devices. Could be som
Van, Its Part 15, actually. What model is it? Copies of the data may be searchable on the FCC's Web site at http://www.fcc.gov/oet/fccid/ under its FCC ID number. For Amateur Radio related complaints
I believe that the presence of harmful interference outside a residence (in this case apparently 200 feet away - and to WWV) makes it possible for the FCC to act -- and for Riley Hollingsworth to app
Jeff, I suspect your friend has electronic ballasts (the "power supplies"). These are efficient but can generate RFI. Take a look at http://www.icecapinc.com/pdf/660.pdf . This ballast will run up to
re: Your Internet article "Hydro-Québec to test internet over power lines" Gentlemen! It is bad enough that RCI is under-funded almost to the point of invisibility, but that CBC staffers could
