Intermittent Static

[ThomasB3131]

Hello

I have a uniden grant XL, paired with a a solarcon A99, connected with 50ft of RG8X coax.

Every so often I get a very harsh static noise that will persist for about a week and then stop.

I have tried to locate the origin of the noise by taking my handheld CB and walking around the house to try and locate it, but have only been able to narrow it down to one end of the house.

I have been trying to figure it out for a while now.

Anyone have any ideas?

maybe power lines?

 

[ThomasB3131]

Could be, but when I get close to the power lines with my handheld it gets weaker. If it were the power lines would'nt it be a constant noise?

 

[ThomasB3131]

I have an audio clip of it but it won't let me put it in a post.

are you sure it's not a connection issue? Does it happen after rain or wind or heat or cold?
I had a connection that had been 'water proofed'; but 3 days after it rain, I would get crackling after I keyed up for a few days. Turns out some water got into it and would short just a bit.

No it's just at random. It does not happen after it rains or anything, it just comes and stays for about a week and then goes away. It has only happened 3 times so far.

And I have had it set up for about 6 months and we have had plenty of rain here in Arkansas lately.

I also forgot to mention that I can hear it just a little bit on my 2 meter radio as well, and I have my 2 meter antenna set up in the house.

Use a handheld with AM receive. Easier to track source, but you have to get close to the source. I use an HT with airband an a handheld 4 element Yagi.

Well that's sort of what I did with the handheld CB, but the noise is covering a large area. I did narrow it down yesterday to one of two things; one it might be the power lines coming into the house or the smart meter for our electricity that uses the Internet to transmit the data to our power company.

But that meter would'nt transmit a week at a time would it?

Tracking down RFI can be a challenge. The first thing, is to rule out a source within your house. Trip each breaker one by one to see if it vanishes. If that fails, then shut off the main breaker and hook the rig to battery power. If noise is present, then the source is outside the house.

Hearing this noise on VHF, means the source is very close. I'd like to hear a recording if you can post it.

 

[ThomasB3131]

I do have a recording but it won't let me attach it.

What file extension will the thread take? I have tried m4a and mp3 but it won't take either of those.
