Power line noise ?
Hi everyone, I have this noise that is quite annoying and when I go outside with my portable radio it's very loud when I stand under the 10Kv line going over my garden, I followed this last night on foot through a field in the dark for some distance and it's the same doesn't increase or decrease.
Tonight I went out in the car with the radio and passed a house with an incredibly noisy LED flood light.
The noise is audiable from around dark and I don't know when it stops because I'd most likely be in bed so I'm wondering if this LED noise can travel from this light through the Persons house wiring and through the transofrmer on the pole and back out on this same 10 Kv line ? this house is around 1.5-2 miles away, surely the LED light can't emit noise this far ?
Listen to it on my Kiwi here http://emeraldsdr.proxy.kiwisdr.com:8073/ and tell me if this sounds like power line noise , QTH is Ireland, so power frequency is 50 Hz. Tune to 6920 Khz and you will hear the Noise I'm talking about, it can be heard at different frequencies.
Sounds similar to the noise emitted from the LED floodlight 1.5-2 miles down the road but yet if I stand under the 10kv line it's really loud on the portable.
And why would it be only after dark ?
