Hi. I've bought a new speakers recently, and they are pretty powerful, compared to the ones I've had. The old ones were from a market, we could say...
Anyway, I hear some sounds, not radio, it's like Morse's alphabet messenges, it sounds like that. Static, I think it's called in English. So I've tried to investigate a little, what could cause this sound:
A fridge ~3 meters away,
Antennas on the other side of the house, 2 satellites and one old (I live in kinda... undeveloped country...).
I found nothing else around, that could exceed any electromagnetical impuses, or something like that, which could possibly cause such things.
So anyway, could any of these things cause that sound?
