Suspected Intentional Home Audio Interference

How is this relevant in the least. Nothing has been mentioned about satellite or cable, or stealing of service.

Do you have any idea of what is going on here?

THE WHOLE THING IS BIT OFF THE WALL.........REALLY!


RIVER.

Honestly? I think you are just in a bad spot and are in a location where all your electronics are just going goofy on ya. You should find a 1-800 number for Roswell and have them come and look at your property.
I also agree with bearvp though. I don't think that puting the fear of God in someone is a crime. (If you do it right )

Usually if I have a neighbor that is pissing me off lately I'll decide to pack up my assault rifle and pistol to go shooting when they are outside so they can see my hardware. Usually they stop bothering me when they see the heat.

notions of militaristic violence. My city certainly has banned any civilian use of firearms within the city limits & we encompass well over 100 square miles of mostly empty desert. Deeply creased arroyos provide easy safety of aim as to ricochets, but the law is the law.

I'd suggest some knowledgeable survey of the premises by an electrician who knows well the consequences of oscilloscope examination. If your residence has particularly poor grounding, youy could be generating an enormous mass of elecrtrical "fuzz."

Shouldn't that sort of analysis be done before planning & plotting dire consequences which are way over the line?

this is all in good fun. No ones serious. Except for the intial poster that can't enjoy his home entertainment. That sucks and is a very serious matter.

Right, except for the police, courts and lawyers. The threat of physical violence to someone is for the braindead and not a way to a successful resolution

This is how bad things can get sometimes between neighbors.... not for little kids

If my neighbor is in fact using a low power FM transmitter to overwhelm my FM reception, would I be seeing a high amplitude signal at the frequency I am trying to listen to (96.1 mhz) as I monitor with my spectrum analyzer and a scanner antenna, or would this jamming signal be appearing at some other frequency I need to look for? Again, I don't actually hear any other radio transmissions over my systems, just repetitious minor sound level reductions and returns to normal, sometimes most distressingly, extended total cut off, or occasionally a rapid spike in volume of the music I was listening to. These don't occur all day but only at select times coinciding with my neighbor's presence. Any further thoughts to help me zero-in on the most likely way my reception is being "attacked" - RF transmission, electrical power, other? Thanks.

Well there will be a spike at the frequency where the radio station is broadcasting, from the station itself. What you want to look for is, when you experience fading or total signal loss, if the spike at this frequency gets larger, or another spike occurs somewhere on the spectrum analyzer that coincides with the interference, then you can be fairly sure that it is an outside source which is causing the problem.

One thing before everyone gets too far, just because your neighbor may have something that is causing interference does not mean that it is intentional or that he is even aware of it. Plenty of devices are made with poor shielding these days and leak RF energy. Don't be too quick to condemn the guy. I know you mentioned haveing a "history" with him, but making accusations of intentional jamming won't help your relationship, especially if they aren't true.

I remember reading about problems with CD playback too. It seems unlikely that there would be much RF interference could do to that. Could it be some IR interference? Do the receivers have wireless remotes? I've had trouble with this in the past - in my case poorly designed "dim-able" (pulsing) CFL fixtures causing some previously well behaved electronics to "go nuts" with symptoms similar to trailuser's Not only would volume levels change - sometimes my TV would turn itself on ...at maximum volume! Covering the IR sensor stopped the seemingly spontaneous behavior - and of course made nothing controllable (grin) but at least it helped pinpoint the trouble.
I don't want to sidetrack the RFI discussion. I just want to be sure the IR remote issue is off the table before we gradually turn trailuser's home into a giant Faraday cage

How exactly is this guy being cocky? He saw your antenna and not only informed you that he was a ham radio operator but said that he hopes he doesn't cause you any interference. As far as having antennas in his yard, it is a requirement of the hobby. Would he also be cocky if he enjoyed motorcycles and had one or two in the yard?

One of the biggest problems with neighbors who are experiencing interference is that in many cases they will not say anything or do anything except get mad and talk behind the back of the person who is causing it. Your new neighbor already expressed his concern that he might cause interference for you, so go tell him what is happening. You can't expect it to stop if he doesn't know its occuring.

I am a ham and I have had the circuit breaker plugs like the one on your blow dryer buzz and trip when I transmit. I have not heard of the motion lights coming on, but it is certainly possible. The only thing that would run your electric bill up is if the lights are on all night.

Again, tell him. You don't need to assume he will be defensive or resistive to doing anything about it. You don't need to build a case against him. Just explain the problem to him and in all likelyhood he will be more than happy to work with you to fix the problems. Sometimes small filters can be put on appliances that experience problems, or simple things can be done which will make both people happy, for instance: You unplug your hair dryer when you aren't using it and he agrees not to transmit between 7 and 8am when you dry your hair. Sometimes reducing the power output of his radios or moving an antenna can solve the problems too.

If you have any questions, please post them. Also let us know how you make out with this problem.

Hi my neighbor has been around here longer than I. We are good friends in the past and I should have no problems talking to him. But I don't even know if it's his ham or my radio's. He has a huge tower and it used to interfere with the cable a long time ago, not now.I have 3 cars on a ford 95 aerostar(reception is perfect on am/fm), a 95 gmc safari(new radio bad reception on am)(seems to be coinciding with the engine and increases with the gas pedal being pushed) and my new car a 2003 hyuandi (am has interference and dosen't seem to coincide with the gas/ignition). I think I have three differnet situations here but can anyone point the cause/solution to me? thank you

Remember, a tower in and of itself can't cause interference. It is the RF emitted from an antenna when your neighbor transmits which could potentially cause problems. This means that interference from your neighbor would occur for several seconds at a time separated by breaks where he would be listening to someone talking back to him. If your interference is constant and occurs almost all the time then its not your neighbor. (He won't be on the radio all the time)

The interference you hear with the Safari is definitely from the vehicle, probably electrical noise from the ignition coil and spark plug wires.

The Hundai could be from something in the vehicle but could be something external too. It could be something in your house causing the problem. I get terrible interference with a Belkin switch and its not even wireless.

Since very few people listen to AM radio anymore, car manufacturers may have gotten lax in the shielding which is required to keep interference out since it would only effect very few people.

Remember, unless it sounds like your listening to half of a conversation, it won't be someone on a ham radio.

Hope this helps.

for the 95 gmc safari w/ the new system, could be the battery is not big enough to power the car + the new system, the alternator could just be starting to go or the battery is just needs to be replaced (check the date on the battery they are normaly good for about 5-7 years). It could also be feedback from the cars electrical system, if it is that, you would have to talk to the installer.

for the 2003 hyuandi, mostliky just needs a better antenna

I checked a few things on the hyuandi. The battery reads 12.8v dc checked with a digital multimeter. and with the car running reads 13.5v dc. now I did some more detective work and there is one channel that comes in real clear. It is the one that is local. all other channels are interfierd with by something because the further away I get from my county the better am comes in. Any ideas?

Farther away from your county? Thats probably a long way. This sounds less like interference and more like you are in a location that is for geographic reasons, not good for receiving broadcast radio stations. When you drive beyond your county, you are probably in a better location. This can be elevation and/or position relative to hills and mountains.

This may be the case. But also another car I have with a ford stock radio has not interference at all. Boy this is like an Algebra equation. lol

Get all the evidences and report him to the police. People with ray gun is dangerous...and I bet he's loaded too.
By the way, how did you found out he also have invisible light as well?
