This house is 45 years old. Any device with a speaker... keyboard, telephone, radio, cd player... during the day, from time to time... will transmit this weird sound. It sounds kinda like morse code!

Sometimes, there is a "buzz" before it starts into the morse code sound.

Any clue what this could be? I guess I should pay attention and see if has only happens when a/c is running.

It seems to be getting worse.

Could be a ham radio operator in your neighborhood. Look for a tall antenna mast on the roof or in the backyard. Walk around with a portable radio and see if the signal gets stronger.

These people are usually quite cooperative. If you tell them about the problem, they will fix it.

.

In morse it means : B B B
A ham-amateur needs more to setup a connection

Sometimes these signals come from cellphones while they let the provider know "I'm alive"

Put them in the neighbourhood of an amplifier, tv, computer or keyboard.... and voilá !

It could something more serious..a wire connection or frayed wire may be arcing under a load..Do any of your lights flicker?

I agree with Roel. I often get a random sound just like you explain. And it comes from varying sources. At work I sometimes get it from a radio/boombox thingy. At home on my pc, radio and TV also. I believe it is caused by both cellphones and cordless phones of any type that are in proximity of a reciever/amp/speaker.
I suggest perhaps asking the phone co?
good luck

Don't worry, I get this all the time, everytime a space ship goes by...Just kidding.

Check to see if the wind is blowing outside when this happens. The power connections to your home should be checked and retightened periodacally,(heat and cold causes expansion and contraction will loosen lugs) A slight breeze moving the wires will cause static, and arcing making this sound.

Call your power company for a free check and lug tightening from transformer to the meter. (most power CO.'s does this free)

meter/service intrance box should be retightened every few years also..........Cheers....Pose

I have had this from time to time, and it seems to be from cell phones placed near the equipment. Is this a possibility in your case?

Graham

I will check, I have a cell phone. No cordless phones in the house.

Bill,

Roel is correct. It is Morse code. I used to be a ham radio operator and we would send that before transmitting CQs and call signs. It sort of means attention I going on the air. You could look for a tall antenna all day and still not find the source. The ham may be using a longwire or dipole antenna.

Of course other sources of interference can find their way into your amp but this sounds like Morse code.

Tom

Tom is right! The likelyhood of finding the culprit antenna is akin to being struck by lightning on a clear, January day.

As stated earlier, living in an older home usually means most of the electrical outlet connections are no longer firm. While this takes a little time, it's well worth it to snug down the screws attaching the wires to each outlet. Over the years, in my case 35, they will become loose from repeated expansion and contraction due to temperature changes. This makes for poor grounding circuits and low voltages, conditions that can also become a fire hazard. I tightened all of my connections two years ago, and this was the 3rd time I did it. It only took a few hours, but nearly every connection was loose enough to get a slight turn on the screwdriver. While a poor connection would likely not pose a fire threat if it were just hooked up to a lightbulb, if the same connection was used for a window air conditioner or de-humidifier the potential is very real.

Play it safe and check them out,

Gary

Well, I think Roel has it figured out. This sound occurs when I have my cell phone in the room. It comes over telephone, keyboard, radio, etc. and the cellphone is within a few feet of wherever it is emitting from.

It's great you found out what is was/is !

Thanks for letting us know.
